Renting vs Buying in DFW: The Real Math (2026)

Most rent versus buy advice is a rule of thumb pretending to be arithmetic. The real calculation has about nine inputs, four of them are specific to Texas, and two of them are the ones people leave out.

This post is the metro-wide version. If you are looking specifically at Plano, the older and narrower Plano rent versus buy post goes into that submarket in more depth. Everything here applies to both.

Month One: Renting Wins, and by More Than It Used To

Start by conceding the obvious. In almost every North Texas submarket right now, the monthly cash cost of renting a comparable home is lower than the monthly cash cost of owning it. Not slightly lower. Often several hundred dollars lower.

That gap comes from four places, and the third one is the local specialty:

• Mortgage rates well above the 2020 to 2021 floor
• Prices that rose sharply and did not give it back
• A property tax burden that is high by national standards, because Texas funds government without an income tax
• Homeowners insurance in one of the most hail-exposed regions in the country

Anyone telling you owning is cheaper on day one, in this market, is comparing a mortgage payment to a rent payment and quietly dropping the tax and insurance lines. It is not cheaper on day one. That is not the argument for buying.

Why It Flips

Three forces work in the owner’s favour and all three take time to matter:

1. Rent rises and principal and interest does not. This is the big one. Your P and I on a thirty-year fixed loan is the same number in year fifteen as in year one. Rent is not. Even modest annual increases compound into a large gap over a decade, and the gap widens every year.
2. Amortisation.Early payments are mostly interest, which is why short holds lose. But the principal share climbs every month, and by year seven a meaningful slice of each payment is going into your own balance sheet rather than someone else’s.
3. Leverage on appreciation. You control the whole asset with a fraction down, so a modest percentage gain on the house is a large percentage gain on your equity. This cuts both ways and should be assumed conservatively, not optimistically.

The Four Texas-Specific Terms

A national rent versus buy calculator will get this wrong, in both directions, because it does not know about these.

The cap in particular changes the shape of the curve rather than just its level. In a fast-appreciating suburb, an owner’s tax bill grows in capped steps while a renter’s landlord is passing through the uncapped market value. Details are in the appraisal cap explainer and the homestead exemption guide.

There is a fifth term in some neighborhoods that will wreck the comparison if you miss it: a MUD or PID assessment on top of the ordinary tax rate, common in newer master-planned developments. Check for it before you model anything.

The Cost of Exit Is the Whole Ballgame

Here is the input most people leave out entirely, and it is the reason short holds lose so decisively.

Buying costs a few percent of the price in closing costs. Selling costs several percent more once commissions, title, and the repairs a buyer negotiates are counted. Together that is a meaningful fraction of the purchase price that must be earned back before you are even.

Which means: the equity you build in the first two or three years is not yours in any usable sense. It is pre-spent on the transaction. Any honest comparison has to run the full cycle, buy and sell, not just the monthly payment. The seller side of it is itemised in what it costs to sell a house in Texas and can be run in the net proceeds calculator.

What Actually Sets Your Break-Even

Ranked by how much they move the answer, based on running this for clients rather than on theory:

1. How long you stay. Nothing else is close. Every other input is a rounding error against the difference between a three-year hold and a ten-year one.
2. Your rent trajectory, not your rent today. A renter facing five percent annual increases has a completely different answer from one whose landlord has held flat for three years.
3. The effective tax rate on the specific house. The spread across North Texas cities is large enough on its own to move break-even by more than a year. See property taxes by city.
4. Your down payment and rate. Which is to say your credit and your loan program, both of which you control more than you think.
5. Appreciation. Last, deliberately. It is the input everyone wants to argue about and the one nobody can forecast. Assume something modest and see whether the decision still holds. If it only works at aggressive appreciation, it does not work.

When Renting Is Simply Correct

I tell people to keep renting fairly often. The clear cases:

• You might move again within three years, for any reason.
• You are new to the metro and have not lived in the city you think you want. North Texas suburbs differ more from each other than newcomers expect. A year of renting is cheap tuition, and the neighborhood matcher plus a lease beats a guess plus a deed.
• Buying would leave you with no cash reserve. In a region where roofs and foundations are ordinary expenses rather than rare ones, that is not a small risk.
• Your income is variable or your job is unsettled. Rent is the flexible obligation. That flexibility has real value and the model above does not price it.

How to Run It on Your Own Numbers

The rent versus buy calculator on this site models the full cycle rather than just a payment comparison, including the sale at the end and the opportunity cost of the down payment. Four notes on using it honestly:

• Use your real renewal history for rent growth, not a national average. Pull your last three lease renewals.
• Use the tax rate for the exact city and district, not a metro average. The difference between two suburbs twenty minutes apart is large.
• Get an actual insurance quote on a real address before you close, not after. It is free and it takes a phone call.
• Test the decision at a conservative appreciation rate. If it only works at an optimistic one, you have found the answer.

One closing thought that no calculator produces. Buying is partly a financial decision and partly a decision about wanting to stay put, paint a wall, and stop asking permission. Those are real and they are worth something. They are just not worth ignoring the arithmetic for.
