A new-construction escrow payment can increase significantly in year two when the first-year estimate was based on vacant land, partially completed construction, or incomplete property-tax information rather than the finished home. Once the completed property is appraised and the mortgage servicer conducts an escrow analysis, the homeowner may have to fund both a higher future tax bill and an existing escrow shortage.
A buyer closes on a newly built home in Cibolo, New Braunfels, Converse, or another growing San Antonio-area community. The interest rate is fixed, the loan amount has not changed, and every payment has been made on time.
Then an escrow-analysis letter arrives.
The monthly mortgage payment is increasing—sometimes by several hundred dollars.
For many homeowners, this feels like a surprise tax increase or a mistake by the mortgage company. In reality, it is often the delayed result of how new construction is appraised, how property taxes are estimated at closing, and how escrow accounts are recalculated after the home is completed.
This does not happen to every new-home buyer, and the size of the increase varies considerably. However, it is common enough that buyers should understand the risk before choosing a home based solely on the initial payment shown by a builder, lender, or online calculator.
Why can a new-construction mortgage payment increase after the first year?
The most common reason is that the first escrow estimate did not reflect the finished home’s full taxable value.
Texas appraisal districts generally value taxable property based on its condition and market value as of January 1. If a home was incomplete on that date, the appraisal may reflect only the land and the percentage of construction completed. If the house did not yet exist on January 1, it generally will not be identified as a completed improvement for that tax year.
After the home is completed and appears on a later appraisal roll at its full market value, the property-tax obligation can be much higher than the amount used to establish the original escrow payment.
The homeowner’s principal-and-interest payment may remain unchanged. The escrow portion of the payment is what increases.
What is included in an escrow payment?
A typical monthly mortgage payment may contain four primary components:
Principal
Interest
Property taxes
Homeowners insurance
Principal and interest are determined by the loan terms. On a fixed-rate mortgage, that portion generally stays consistent.
Property taxes and homeowners insurance can change. When those costs are paid through escrow, the servicer collects a monthly amount and uses the account to pay the bills when they become due.
The Consumer Financial Protection Bureau notes that monthly mortgage payments can rise when property taxes or homeowners insurance premiums increase.
That distinction matters because a buyer may hear that a fixed-rate mortgage provides a “fixed payment.” The principal-and-interest payment may be fixed, but the total monthly amount is not necessarily fixed when taxes and insurance are escrowed.
Why are first-year property taxes sometimes unusually low on a new build?
The appraisal may have reflected only the lot
Consider a home completed in August.
On January 1 of that same year, the property may have been:
A vacant lot
In an early construction phase
Partially framed
Missing major completed improvements
Still recorded under a builder or development account
Because Texas property is generally appraised according to its January 1 condition, that year’s tax value may be substantially below the eventual value of the finished house.
A lender may use the available tax record when preparing a preliminary payment estimate. If that record reflects primarily land value, the tax portion of the payment can look deceptively low.
The home may have been only partially complete
Texas law provides that property under construction on January 1 is valued according to the percentage of construction completed as of that date.
For example, a home that was only 30% complete on January 1 may receive an appraisal that is far below the value of the completed home.
When the appraisal district later values the fully completed property, the taxable value may rise sharply even if local tax rates do not increase.
The original estimate may not have included every taxing jurisdiction
A Texas tax bill can include several local taxing units, depending on the property’s location:
County
City
School district
Hospital district
Emergency services district
Municipal utility district, or MUD
Other special-purpose districts
Texas does not impose a state property tax. Local governments and other taxing units adopt rates and apply them to taxable property values.
That means two similarly priced new homes can have meaningfully different tax obligations depending on the city, school district, county, MUD, or other jurisdictions serving the property.
A home in Garden Ridge may have a different combination of taxing entities than a new subdivision in Cibolo, Schertz, Converse, New Braunfels, or Seguin. Buyers should verify the tax jurisdictions attached to the specific property rather than applying a general citywide estimate.
What happens during the year-two escrow analysis?
Mortgage servicers periodically review escrow accounts to compare:
The amount collected from the homeowner
The actual taxes and insurance paid
The amount expected to be needed during the next escrow year
If the actual bills were higher than projected, the account may have an escrow shortage.
The servicer may then increase the payment for two separate reasons:
1. The future monthly escrow amount increases
The servicer must collect enough each month to cover the newly projected property taxes and insurance premiums.
2. The existing shortage must be repaid
If the servicer already paid a tax or insurance bill that exceeded the balance in the escrow account, the account may be negative or below its required balance.
Depending on the amount and applicable servicing rules, the shortage may be spread across at least 12 monthly payments or handled through other permitted repayment options.
This double adjustment is why the increase can feel so dramatic. The homeowner is not only beginning to fund the higher ongoing expense; the homeowner may also be repaying the prior shortage.
A simplified example of a year-two escrow increase
Suppose the initial escrow estimate assumed annual property taxes of $3,600:
Initial tax escrow: $300 per month
After the completed home is fully appraised, the actual annual tax obligation is $7,800:
Updated tax escrow: $650 per month
Increase needed for future taxes: $350 per month
Now suppose the servicer also identifies a $2,400 shortage from the prior escrow year:
Shortage repayment over 12 months: $200 per month
The temporary payment increase could be:
$350 for the higher ongoing tax obligation
$200 for shortage repayment
Total temporary increase: $550 per month
After the shortage is repaid, part of that increase may drop away. However, the payment would not necessarily return to the original amount because the ongoing tax estimate remains higher.
This is only an illustration. Actual payments depend on the home’s taxable value, exemptions, tax jurisdictions, insurance premium, escrow balance, servicer calculation, and loan terms.
Is the increase always caused by property taxes?
No. Homeowners insurance can also contribute.
Insurance premiums may change because of:
Updated replacement-cost estimates
Changes in insurer pricing
Roof age or construction characteristics
Coverage selections
Deductible changes
Claims history
Weather and catastrophe exposure
Marketwide insurance-cost changes
A buyer reviewing an escrow increase should separate the tax change from the insurance change. The annual escrow statement should show the projected disbursements for each category.
The servicer’s estimate should also be compared with the actual county tax records, appraisal-district records, current insurance declaration page, and any applicable exemption approval.
Does a homestead exemption prevent the year-two jump?
Not necessarily.
A residence homestead exemption can reduce taxable value for qualifying homeowners, but it does not erase the difference between a land-only appraisal and the value of a finished home.
Texas allows qualifying property owners who acquire and occupy a home after January 1 to apply for the general residence homestead exemption during the year rather than waiting until the following January. The precise benefit depends on eligibility and the taxing units involved.
The homestead appraisal cap is also frequently misunderstood. It generally does not immediately limit the first appraisal of a newly completed home to a 10% increase over the lot value.
Bexar Central Appraisal District explains that the homestead cap begins January 1 of the tax year after the first year the homeowner qualifies for the homestead exemption.
In practical terms, a buyer should not assume:
“My homestead exemption means the property value can only go up 10% next year.”
The initial transition from vacant land or partial construction to a completed residence can work differently from later annual capped-value calculations.
Why does this matter in Garden Ridge and the San Antonio–New Braunfels area?
New construction continues across portions of Bexar, Comal, and Guadalupe counties, including communities near Schertz, Cibolo, Converse, New Braunfels, Seguin, Bulverde, and the I-35 corridor.
In these areas, a property’s total tax obligation can vary based not only on its price but also on its exact taxing jurisdictions and exemptions.
For example:
Garden Ridge properties are generally located in Comal County.
Some New Braunfels-area properties may be in Comal County, while others are in Guadalupe County.
Schertz and Cibolo properties may fall within different county, city, school, and special-district combinations.
New subdivisions may include MUD or other district taxes that are not reflected in a nearby resale home’s tax rate.
Comal Appraisal District currently notes that qualifying homeowners receive at least a $140,000 school-district homestead exemption, while Comal County provides a 20% local-option homestead exemption. Those exemptions do not necessarily apply in the same way to every taxing unit, and eligibility must be confirmed.
The correct question is not simply, “What is the tax rate in this city?”
A more useful question is:
“What taxing entities apply to this specific property, what exemptions may apply to me, and what might the completed home’s taxable value be?”
How can buyers estimate a more realistic future payment?
Start with the expected completed-home value
Do not base the estimate solely on the current tax bill if the tax record still reflects land or partial construction.
A reasonable planning estimate may begin with:
Contract price
Expected market value upon completion
Appraisal-district treatment of comparable completed homes
Builder and lender tax estimates
Current tax rates for the property’s exact jurisdictions
The contract price and appraisal value are not automatically the same as taxable value, but they can provide a more realistic planning reference than a vacant-lot assessment.
Identify every taxing unit
Review the appraisal-district or tax-office record for the property.
Confirm whether the home is subject to:
County taxes
City taxes
School-district taxes
MUD taxes
Emergency-services-district taxes
Hospital-district taxes
Other special assessments or fees
The tax assessor-collector generally calculates and collects taxes using values certified by the appraisal district and rates adopted by the taxing jurisdictions.
Estimate taxes using taxable value—not just the sales price
A simplified property-tax calculation is:
Taxable value × tax rate ÷ 100
Each taxing unit may apply its own rate and exemptions. The calculations are then combined to determine the total bill.
Because exemption structures differ, a blanket calculation using the purchase price and one combined percentage should be treated as a planning estimate rather than a guaranteed bill.
Ask whether the lender used land-only taxes
Before closing, ask the lender directly:
Is the tax estimate based on the completed home or the current tax record?
Does the current tax record include the finished improvement?
Which taxing jurisdictions are included?
Does the estimate assume a homestead exemption?
How would the payment change if the completed value is close to the purchase price?
Is the initial escrow deposit expected to be sufficient under that scenario?
These questions can reveal whether the attractive initial payment is likely to remain realistic.
Build a monthly reserve
When the current tax bill reflects an incomplete home, consider saving the difference between:
The lender’s initial escrow estimate, and
A conservative estimate based on the completed property
That reserve may help absorb an escrow shortage or payment adjustment later.
Keeping the money in a separate savings account also makes it easier to distinguish a future housing-cost adjustment from normal spending.
What should homeowners do when the escrow letter arrives?
Do not assume the calculation is correct, but do not ignore it either.
Review the following:
Current appraisal-district value: Does it reflect the correct property and completed improvements?
Taxable value: Are approved exemptions shown?
Actual tax bill: Did the servicer use the correct amount?
Insurance premium: Does it match the current policy?
Escrow balance: Were all deposits and disbursements properly recorded?
Shortage amount: How much is being recovered, and over what period?
New projected payment: How much is permanent and how much is temporary shortage repayment?
If the servicer failed to pay a bill or used incorrect information, contact the servicer promptly. The CFPB advises homeowners with an escrow account to contact the servicer immediately if a tax bill indicates that required taxes were not paid. A written notice of error may provide additional protections when a servicing error is suspected.
Can you protest the new appraised value?
Texas property owners may generally protest an appraisal they believe is incorrect or above market value, subject to applicable deadlines and procedures.
The question is not whether the appraisal increased substantially from the prior land-only value. The more important issue is whether the completed home’s January 1 market value and property characteristics are accurate.
Review:
Square footage
Construction status as of January 1
Lot size
Improvements
Property classification
Comparable sales
Exemptions
Ownership and mailing information
The Texas Comptroller advises property owners who disagree with an appraised value to use the protest process described in the notice of appraised value.
A large percentage increase by itself does not prove that the appraisal is incorrect when the prior value represented only land or incomplete construction.
When should buyers start planning for the higher payment?
Ideally, before signing the purchase contract—or at least before the financing contingency and closing process are complete.
New-construction buyers should evaluate both:
The payment shown at closing
A projected payment after the home is fully assessed
This is especially important when:
The current tax record shows vacant land
The subdivision is newly developed
The home was completed after January 1
The lender’s estimate appears unusually low
The community includes special taxing districts
The buyer’s budget has little room for payment changes
The builder is advertising a temporary rate buydown
A temporary interest-rate buydown and an underestimated escrow account can create two separate future increases. Buyers should understand the timing of both before deciding whether the long-term payment fits comfortably.
The bottom line
A year-two escrow increase on a Texas new-construction home is often caused by timing rather than a sudden change in the mortgage itself.
The first payment may have been calculated using a property-tax record that reflected only the lot or partially completed construction. After the finished home is appraised, the servicer may need to collect more for future taxes while also recovering an escrow shortage from the prior year.
The best protection is not trying to predict the bill to the exact dollar. It is recognizing when the initial estimate may be incomplete, verifying the property’s taxing jurisdictions, estimating taxes using the completed home, and leaving room in the household budget for adjustment.

Frequently Asked Questions
Why do escrow payments increase on new-construction homes?
Escrow payments often increase because the first estimate was based on a tax record that did not include the completed home. In Texas, property is generally valued according to its condition on January 1. If the home was vacant land or only partially built on that date, the first tax obligation may be much lower than the eventual bill. When the servicer updates the account, it may collect both the higher future amount and repayment of an existing shortage.
How much can a new-build mortgage payment increase in year two?
There is no standard increase because the amount depends on the difference between the original estimate and the actual taxes and insurance. A payment could change modestly or by several hundred dollars per month. The largest adjustments often occur when the original tax estimate reflected primarily land value. Buyers should calculate a planning range using the completed home’s expected value, exact taxing jurisdictions, likely exemptions, and current insurance premium.
Are first-year property taxes lower on every new-construction home?
No. First-year taxes are not automatically lower on every new home. The result depends on when construction began, how complete the home was on January 1, when the buyer closed, and whether the lender estimated taxes using the completed value. A lender may establish escrow using a conservative projection even when the current tax bill is low. Buyers should ask what value and tax rate were used rather than assuming the first-year payment will be artificially low.
Can a homestead exemption prevent an escrow shortage?
A homestead exemption may reduce the taxable value, but it does not guarantee that an escrow shortage will be avoided. The original estimate may still have been based on vacant land or partial construction. The homeowner must also apply, qualify, and confirm that the exemption appears on the appraisal record. Some exemptions apply differently across school, county, city, and special-district taxes, so the total benefit varies by property.
Why did my Garden Ridge new-construction payment increase?
A Garden Ridge payment may increase when a completed home in Comal County replaces a prior land-only or partial-construction appraisal. The servicer may also be adjusting for insurance or recovering a shortage. Review the Comal Appraisal District record, the tax bill, approved homestead exemptions, insurance declaration page, and escrow statement. Because Garden Ridge properties may have different taxing entities than homes in nearby Schertz or New Braunfels, use the specific property record rather than a regional average.
What should San Antonio-area buyers ask before closing on a new build?
Ask whether the lender’s tax estimate is based on the completed home, the vacant lot, or a partially built improvement. Buyers should also request the full list of taxing jurisdictions, determine whether a MUD or other special district applies, confirm whether the estimate assumes a homestead exemption, and ask for a projected payment using the finished home’s expected value. These questions are particularly important in developing areas of Bexar, Comal, and Guadalupe counties.
When should I apply for a Texas homestead exemption after buying a new home?
Apply after you own and occupy the property as your principal residence and meet the eligibility requirements. Texas permits qualifying homeowners who acquire a residence after January 1 to apply during the year. Confirm current requirements with the appropriate appraisal district and verify that the approved exemption appears on the property account. Filing the application does not automatically correct a lender’s escrow estimate, so provide updated tax information to the mortgage servicer when appropriate.
Should I pay an escrow shortage in full or spread it over monthly payments?
The better option depends on your cash reserves, the shortage amount, and whether paying it immediately would meaningfully reduce the new monthly payment. Paying the shortage does not eliminate the ongoing increase caused by higher taxes or insurance. Before making a lump-sum payment, ask the servicer to show the payment both with and without the shortage repayment. Avoid using emergency savings if doing so would leave the household financially exposed.
When should I seek professional guidance about a new-construction payment estimate?
Seek guidance before closing when the current tax record reflects land, unfinished construction, unfamiliar special districts, or a payment that seems unusually low for the home’s price. A knowledgeable local real estate professional can help identify property-specific questions and comparable tax records. A lender or servicer should explain escrow calculations, an appraisal district can address value and exemptions, and a qualified tax professional or attorney can answer legal or tax-specific questions.
