The incentives are real. So are the appraisal games, the first-year tax trick, and the fight you face when you sell against the builder’s next phase. Sometimes a new build is the right call. A lot of times it isn’t. The difference is never luck: it is who is in your corner and whether the numbers work.
Buy a new build only when the math works at market value, not builder value. That means comps from established neighborhoods nearby, an independent Loan Estimate, the real tax bill at full assessment, and a plan to stay at least seven years. In San Antonio, Redfin found 10% of listings in 2025 were at risk of selling for less than the owner paid, versus 6% nationally, and 30% of homes bought after the pandemic. Many of those were new builds in fast-growing outer suburbs.
The appraisal confirmed the price and the comps all matched. So why are so many San Antonio new-build owners struggling to sell two or three years later?
| Problem | What happens |
|---|---|
| Circular appraisals | The appraiser uses comps from the same subdivision: same floor plan, same builder, same incentive-inflated prices. Every comp confirms the last one. The price looks real, but it is builder value, not market value. |
| The next phase undercuts you | When you sell in year two or three, the builder opens the next phase: the same house, brand new, with fresh incentives and a lower effective price. You are selling a used version against their new one. |
| Slow inventory | New homes in the San Antonio area averaged about 104 days on market in May 2026. That is the market those buyers walked into without running the numbers first. |
A good agent pulls real resale comps, meaning non-builder sales in established neighborhoods nearby, before you sign anything. That number is your true market anchor. If there is a big gap, you need to know it before closing, not after.
Every free incentive is money moving from one of the builder’s pockets to another. You have the right to choose your own lender, your own title company, and your own inspector.
| Builder pocket | What to know |
|---|---|
| Their mortgage company | Can earn origination fees and rate markup on your loan. A "free" rate buydown may be priced back in somewhere else. Ask an independent loan officer to compare. |
| Their title company | "We’ll cover closing costs" sometimes means paying more for your title and escrow through their affiliate. In Texas you can shop title. |
| Their warranty | The builder warranty is a product with limits. Read what it actually covers and for how long. |
| Their incentive package | Rate buydowns, free upgrades, and covered closing costs are all designed to make the deal feel special. They are budgeted into the price you pay. |
| Agent bonuses | Some builders pay buyer’s agents well above the usual commission to move slow inventory. A good agent will tell you up front how they are being paid on the home. |
Builders often quote your property taxes based on the value of the lot, before the house is finished. That makes the payment look great. Then the appraisal district values the completed home, and the tax bill can jump $3,000 to $5,000 or more per year. Your escrow comes up short and your payment goes up.
A good lender calculates the projected tax at full assessment, using the real rate for that subdivision including any PID, SID, or MUD, and sets escrow on that number before you close. Ask for it in writing. See the rates by area in our San Antonio area guide.
| Builder’s side | Your side |
|---|---|
| Sales rep: works for the builder, owes you no fiduciary duty, cannot negotiate against their employer, and verbal promises do not count. | Your licensed Realtor: legal fiduciary duty to you, negotiates price and incentives, shows comps before you tour, and will tell you to walk away. |
| Preferred lender: affiliated with the builder, may not offer the best rate or fees, may quote taxes on land value only, and the builder controls the relationship. | Independent licensed loan officer: every fee disclosed in writing, can often still receive builder incentives, projects real tax at full assessment, and is legally accountable to you. |
| 1. Push for a real price drop first. Builders resist cutting price because it lowers appraisal comps for the whole neighborhood. On slow-moving inventory, it is possible. Push hard. |
| 2. If the price will not move, negotiate incentives, and ask whether they work with an outside lender. Builders will sometimes pass the incentive credit to an independent loan officer if it still closes the deal. Alberto has done it. |
| 3. Use your own licensed lender when you can. Run the comparison. If the builder’s lender wins on total cost, fine. You will never know unless you have an independent Loan Estimate in hand. Send the builder’s quote here. |
| 4. Pull comps from established neighborhoods, confirm the real tax, and plan for 7+ years. If you might sell in under five years, run the full exit math first. |
| New build | Existing home | |
|---|---|---|
| Price and value | Builder sets the comps; incentives can inflate price | Priced against real resale comps |
| Negotiation | Incentives easier than price cuts | Price, repairs, and seller credits all on the table |
| Taxes | Year-one bill can be lot-only; watch for PIDs and MUDs | Full tax history is visible up front |
| Condition | New systems and warranty; punch-list issues | Needs a thorough inspection; may need updates |
| Resale | Competes with the builder’s next phase | Competes with similar resales |
| Location | Mostly outer suburbs: Far West, Schertz, Cibolo, Brooks | Closer-in, established neighborhoods |
| Financing | Builder lender pushes incentives | Any lender; assumable VA and FHA loans possible |
Skip the builder’s package entirely. Build what you want, where you want, with your own team. A one-time close (OTC) loan covers the land, construction, and permanent mortgage in one loan and one closing, with the rate locked before ground breaks.
For VA buyers: $0 down, no PMI, and no payments during construction on eligible programs. It is one of the best products in San Antonio, and most veterans here do not know it exists. FHA and conventional OTC versions are available too.
He’ll pull the real tax rate, check for special districts, and text you the estimated monthly payment. No credit pull.
Send Alberto the builder’s Loan Estimate and the address. He’ll compare the financing, project the real tax bill, and tell you straight whether the deal makes sense. No builder deals. No affiliate kickbacks. Just your best loan.
