Your mother paid about $1,900 a year on that house. The first bill that came to you was $6,400.
Nothing was done to the house. Nobody added a room. The county didn’t make a mistake. Three separate protections came off the property at once when she died, and what you’re looking at is what the house would always have cost somebody who wasn’t her.
This post takes that bill apart. I’ve sat at a lot of kitchen tables with a tax statement between us and a family trying to understand how a number could do that.
The Three Things She Had That You Don’t
The homestead exemption. Texas knocks a chunk off the taxable value of a home somebody actually lives in. It applied to her. The day the house stopped being her residence, it stopped applying.
The over-65 exemption. On top of the regular homestead exemption, Texas gives homeowners 65 and older an additional school-district exemption. School taxes are the biggest line on a Bexar County bill, so this one does a lot of work. It also came off.
The appraisal cap — and this is the one nobody knows about. On a homesteaded property, Texas limits how much the appraisal district can raise the taxable value in a year to ten percent, no matter what the market does. Your mother may have owned that house for thirty years. Every year the market went up more than ten percent, the gap between what the house was worth and what she was taxed on got wider.
That gap doesn’t close gradually when the homestead protection ends. It closes all at once.
So the house that was taxed at a capped value well below market is now taxed at market. On a long-held house in a neighborhood that appreciated — anywhere near the Pearl, Alamo Heights, Olmos Park, parts of the near North Side — that one change can be most of the jump by itself.
The Part That’s Hiding Underneath
Now the one that genuinely blindsides families.
Texas lets homeowners 65 and older file an affidavit to defer their property taxes. Not reduce them. Postpone them. While she owned and lived in the house, the taxes stopped being collectible. Interest accrued quietly in the background.
Thousands of Bexar County seniors do this. It’s legal, it’s sensible, and it’s often the thing that let a widow stay in her house. The deferral ends on sale, transfer, move-out, or death — and then the whole accumulated balance plus interest comes due, the same way back taxes on the property would.
Bexar County’s guidance describes that balance coming due on the 181st day after the qualifying event, with penalties and interest attaching to anything still unpaid after that.
Two things worth knowing.
A surviving spouse aged 55 or older may be able to continue the deferral. Heirs generally cannot.
And here’s the tip almost nobody gets told: you can make partial payments against a deferral in anticipation of inheriting. You don’t have to stand there and watch it compound while probate grinds along. If you know the deferral exists and you have some cash, you can start knocking it down now.
Put It on One Page
Do this with your own numbers rather than mine.
Write down the last tax bill your parent actually paid. Then go to the Bexar Appraisal District, look up the property, and find the current market value — not the capped assessed value she was paying on, the market value.
Call the Bexar County Tax Assessor-Collector and ask two questions: what’s the current effective tax rate for that property’s location, and is there a deferral on the account.
Multiply the market value by the rate. That’s roughly your new annual number, before any deferral balance. Divide by twelve. That’s what the house costs the estate every month it sits.
Then add insurance — and if the house is empty, call the carrier, because a vacant property is usually a different and more expensive policy than the one that’s on it. Add utilities you’re keeping on. Add the mortgage if there is one.
That monthly figure is the real clock. Everything else in the decision is a reaction to it — including whether it’s worth finding out what the house would bring as-is today.
Aaron’s Place on Avalon
Aaron inherited a house on Avalon, up in 78213, from his father.
What he needed wasn’t complicated and it wasn’t dramatic. He wanted to move quickly, because the money from his father’s house was what let him buy the house he actually wanted for himself. Every month the estate held the property was a month he wasn’t where he was trying to get to.
That’s the version of this most people are in. Not a crisis — just a carrying cost running against a plan.
You Don’t Have to Sell
I want to be clear about this because I’m the guy who buys houses and I’d rather you hear the alternatives from me.
If one of the heirs moves into the house and makes it their primary residence, they can file their own homestead exemption and start the clock over on their own cap. That resets most of what you just read.
If there’s a deferral, it can be paid off and the house kept. The balance is a number, not a verdict.
And if the appraised value genuinely looks wrong — not high, wrong — you can protest it. There’s a deadline each spring and the appraisal district publishes the process.
Selling makes sense when the carrying cost outruns what the family gains by holding, or when nobody wants the house and everybody wants the chapter closed. It doesn’t make sense just because the bill was a shock.
I’m not an attorney or a CPA. Before you make a decision with this much money attached, talk to one.
What Families Ask Me About This
Q: How long can we keep Mom’s homestead exemption after she passes? A: Not long, and don’t plan around it. The exemption belongs to the person who lived there. Contact the Bexar Appraisal District and tell them what happened rather than waiting for them to find out — a surprise correction later is worse than a known number now.
Q: What is the 10% cap and does it survive inheritance? A: It limits how much the taxable value of a homesteaded property can rise in a year. It’s tied to the homestead status, so it generally does not survive when the house stops being the owner’s residence.
Q: Do deferred taxes disappear when the owner dies? A: No. They become payable. Bexar County describes the balance coming due on the 181st day after the qualifying event, with penalties and interest attaching after that.
Q: Can we pay a deferral off in installments? A: Heirs can make partial payments against a deferral in anticipation of inheriting. Call the tax office and ask how to apply payments to that account specifically.
Q: Can I protest the new appraised value? A: Yes, through the Bexar Appraisal District’s protest process, which has a deadline each spring. Protest when you think the value is wrong, not simply when it’s higher than last year’s capped number.
Q: What if one sibling lives there and the others don’t? A: The sibling living there may be able to claim a homestead exemption on their interest. How that interacts with the other heirs’ shares is an attorney question, and it’s worth asking before anybody files anything.
A tax bill that triples isn’t a sign something went wrong. It’s the house being taxed the way it would have been taxed for anyone other than your mother.
Knowing that doesn’t make it cheaper. It does let you plan instead of panic — figure out the monthly number, decide whether the family wants to carry it, and move deliberately. The mechanics of selling an inherited home are a separate question you can take up once the number is in front of you.
If the carrying cost is the problem and nobody in the family wants the house, we’ll give you a number on it as it stands, or call (210) 201-6644. And if the deed still isn’t in anyone’s name yet, start there instead — that comes first.
