Down payment options for San Antonio buyers: 3.5%, 10%, and 20% compared
The down payment is the biggest hurdle for most first-time buyers in San Antonio. You do not need 20% to buy — but the percentage you put down directly determines your monthly payment, whether you pay PMI, and your loan options. Here is how the three most common down payment levels compare on San Antonio's $275,000 median home at a 6.5% rate.
| Down payment | Cash needed | Loan amount | Monthly P&I | Est. PMI/mo |
|---|---|---|---|---|
| 3.5% (FHA minimum) | $9,625 | $265,375 | $1,677/mo | $199/mo |
| 10% | $27,500 | $247,500 | $1,564/mo | $186/mo |
| 20% (no PMI) | $55,000 | $220,000 | $1,391/mo | — |
P&I at 6.5% 30-year. PMI estimated at 0.9% of loan amount annually — actual rate varies by lender and credit score. Tax and insurance not included in this table.
FHA loans (insured by the Federal Housing Administration) allow down payments as low as 3.5% with credit scores of 580+. The trade-off: FHA loans require both an upfront mortgage insurance premium (1.75% of the loan amount, typically rolled into the loan) and an annual MIP of approximately 0.55–0.85% of the loan balance — which does not automatically cancel when you reach 20% equity, unlike conventional PMI. For buyers who can manage a 10% down payment, a conventional loan with cancellable PMI is usually more cost-effective long-term than an FHA loan.
Closing the affordability gap in San Antonio
If the numbers above show that San Antonio's median home is currently out of reach, there are several strategies that can close the gap without waiting years to save. Down payment assistance (DPA) programs — offered through state housing finance agencies, local governments, and select lenders — can provide grants or low-interest second loans of $5,000–$30,000+ toward the down payment and closing costs. Most DPA programs require the buyer to be a first-time purchaser (or not have owned in the past 3 years), meet income limits (typically 80–120% of area median income), and complete a HUD-approved homebuyer education course.
A less expensive home in a nearby neighbourhood or suburb can dramatically change the numbers. Buying at $220,000 — 20% below the city median — reduces the required income from $82,286/year to approximately $65,829/year and cuts the down payment by $11,000. Expanding the search radius is often the most practical path to homeownership in high-cost metros.
Improving your debt-to-income ratio (DTI) is the other primary lever. Every $500/month you eliminate in existing debt payments (student loans, car loans, credit cards) increases your maximum qualifying home price by approximately $71,615. Paying off a car loan or consolidating student debt before applying can meaningfully expand your buying power without changing your income.
San Antonio housing market 2026
San Antonio has been one of the more consistently affordable major Texas metros, though prices have risen meaningfully since 2020. Military installations — Fort Sam Houston and Joint Base San Antonio — provide stable employment that buffers the market against economic cycles. The Pearl District and King William area command premiums; suburban expansion to the north and west offers continued affordability.

How to Calculate Home Affordability: The 4 Rules Lenders Use
Home affordability is calculated using four ratios: the 28% front-end rule, the 36% back-end rule, the 43% DTI ceiling, and the 3x–5x income rule. Most buyers are constrained by their back-end DTI, not their income. A worked example shows exactly what you can borrow at $90,000 gross income with $500/month in existing debt.
How to Remove PMI: When It Cancels Automatically and How to Request It Early
PMI cancels automatically at 78% LTV but you can request removal at 80%. With appreciation, a new appraisal can eliminate PMI years earlier. At $1,200/year per $200,000 borrowed, removing PMI 5 years early saves $6,000. Here is the exact process, the lender rules, and when refinancing beats an appraisal.
