📞 About to Close? Let's Make Sure You're Ready for What Comes Next.
Buying a home is one of the most significant financial decisions you'll make. The closing table gets a lot of attention — but the months that follow are where most first-time buyers get surprised.
I walk every buyer I work with through this conversation before we close. If you have questions — about this process, or about buying in San Antonio — I'm here.

No pressure. No pitch. Just real answers from someone who knows this market.
You closed. You have the keys. You're officially a homeowner.
And then the letters start arriving.
Some are expected. Some are not. And a handful of them — if you weren't prepared — will make you wonder whether something went wrong.
Nothing went wrong. But nobody fully explained what was coming.
This guide fixes that.
Your First Payment Isn't Due When You Think
Your first mortgage payment is typically not due the month you close.
Mortgages are paid in arrears — the payment in Month 2 covers Month 1. Close April 15th → first payment not due until June 1st. That's not a grace period. That's just how mortgages work.
What you do pay at closing is prepaid interest — a line item on your Closing Disclosure covering the partial month from your close date to month's end. It's already been collected. You're current.
Pro tip: Ask your lender to walk through your Closing Disclosure line by line before closing day. It should never be the first time you see those numbers.
Your Monthly Payment May Not Match What You Were Quoted
When your lender gave you a payment estimate, they used projected figures for property taxes and homeowners insurance — both real numbers, but estimates.
In Texas, where property tax rates rank among the highest in the country, the gap between estimate and reality can be meaningful.
Your escrow account collects monthly installments toward both bills. If either estimate was off — or if taxes are reassessed upward after closing — your monthly payment adjusts at your next annual escrow review.
Your payment in Month 14 may be different from Month 1. Plan for it rather than be surprised by it.
If there's a shortage, you'll typically have two options: lump sum or spread over 12 months. Call your lender and ask — don't assume it must be paid all at once.
The Supplemental Tax Bill: Texas-Specific and Frequently Missed
This catches new buyers off guard every single year — and I make sure every client understands it before closing.
In Texas, property taxes are assessed based on value as of January 1st. When you buy mid-year, the existing bill was calculated using the previous owner's assessment — and often their homestead exemption.
Once the property transfers, the county may issue a supplemental tax bill for the difference. This is completely separate from your mortgage escrow. It arrives as its own statement, months after closing — sometimes well into the following year. If you're not expecting it, it looks like an error. It isn't.
New construction buyers: your first-year taxes are often based on land value only — before the structure is assessed. When the completed home hits the tax roll, your annual bill adjusts. Sometimes significantly.

Homeowners Insurance: The Annual Renewal Surprise
Your premium is locked in when you close. But it renews every year — and in Texas, premiums have been climbing due to weather exposure.
At renewal, your escrow recalculates and your lender sends a new monthly payment letter. Review it when it arrives. If the increase is significant, shop around. I'm happy to refer you to trusted local insurance professionals who know the San Antonio market.
HOA Dues: The Bill That Lives Outside Your Mortgage
If your home has an HOA, those dues are almost never collected through your mortgage escrow. They're a completely separate bill — monthly, quarterly, or annually — and entirely your responsibility to track and pay directly.
Missing HOA payments in Texas can result in late fees, liens, and in extreme cases, collection actions.
The day you close: set up auto-pay. Put a calendar reminder. Treat it exactly like a utility bill.
Home Maintenance: The Number That Catches Everyone
Standard guidance: budget 1–2% of your home's value annually for maintenance and repairs.
On a $300,000 home — that's $3,000–$6,000 per year. On a $400,000 home — $4,000–$8,000.
That number feels abstract until the HVAC needs a service call, a fence blows over in a Texas storm, or the garbage disposal quits. None are crises individually. But they arrive without warning and they add up.
The smartest financial move the month you close: open a dedicated home maintenance savings account and contribute monthly — even $150–$250 per month changes the entire emotional experience of year-one homeownership.
One More Thing: File Your Texas Homestead Exemption
After you close, file your Texas Homestead Exemption with your county appraisal district — no later than April 30th of the following year.
This reduces your taxable home value by $100,000 for school district purposes. Depending on your county and school district, that's $1,000–$2,500+ in tax savings every single year.
It's free. It takes 10 minutes. File directly with Bexar CAD (or your county's appraisal district). Most first-time buyers miss it because nobody told them. Now you know.
What PITI Actually Means
P — Principal: Reduces your loan balance. Builds equity directly.
I — Interest: What you pay to borrow the money. Early years: most of your payment goes here.
T — Taxes: Property taxes collected monthly into escrow, paid by your lender when due.
I — Insurance: Homeowners premium escrowed and paid at renewal.
Your lender quoted P&I during pre-approval. Your actual payment is PITI — always higher. In Texas, the T is significant. Always ask for the full PITI estimate before making an offer.
Quick Takeaways
✅ First payment due one full month after closing — not immediately
✅ Monthly payment based on estimated escrow that adjusts annually
✅ Texas supplemental tax bills are real, separate from escrow, arrive months later
✅ HOA dues are never in your mortgage — set up auto-pay at closing
✅ Budget 1–2% of home value for maintenance annually from Day 1
✅ File Texas Homestead Exemption by April 30th — saves $1,000–$2,500+/year
✅ Always ask for full PITI — not just P&I
Frequently Asked Questions
What if I can't afford my new escrow payment after an adjustment?
Contact your lender right away. Shortages can typically be spread over 12 months rather than paid in a lump sum. Options vary — but you have to call and ask.
How do I know if I'll receive a supplemental tax bill?
Ask your agent and title company at closing. New construction buyers in San Antonio should always plan for one.
What's the difference between P&I and my total monthly payment?
P&I is the base loan repayment quoted at pre-approval. PITI adds taxes, insurance, and sometimes PMI. PITI is always higher. Confirm the full PITI with your lender before making any offer.
Can my interest rate change after I close?
With a fixed-rate mortgage, no. Only your escrow portion can fluctuate. With an ARM, the rate itself can adjust — confirm your loan type if you're uncertain.
When should I file the Texas Homestead Exemption?
As soon as possible after closing, no later than April 30th of the following year. File directly with your county appraisal district. Free. 10 minutes. $1,000–$2,500+ in annual tax savings. Do not skip it.
What's the smartest financial move to make the month I close?
Three things: (1) File your homestead exemption. (2) Set up HOA auto-pay if applicable. (3) Open a dedicated home maintenance savings account and start contributing monthly.
