FHA vs conventional is the most common loan decision San Antonio first-time buyers face — and the right answer depends on four specific variables that most buyers don’t evaluate in the right order. Credit score. Down payment amount. How long you plan to own the home. And whether the property qualifies under each loan type’s condition requirements. Get those four variables right and the comparison resolves clearly in almost every case. Get them wrong and buyers end up paying thousands more over their ownership period than necessary, or locked into a loan structure they can’t exit without refinancing. San Antonio’s current buyer-favorable market — with real seller concessions available across most communities — adds a fifth variable: how much closing cost assistance you can negotiate changes the FHA vs conventional calculation meaningfully at current price points. This guide walks through the full comparison at San Antonio’s actual price points so buyers can make the right call before they’re pre-approved for the wrong loan.

The Core Difference — What Each Loan Is Actually For
FHA and conventional loans both provide 30-year fixed-rate financing for primary residences — but they’re designed for different buyer profiles:
- FHA loans are government-backed (Federal Housing Administration) and designed for buyers with lower credit scores and smaller down payments. Lower credit minimum (580 for 3.5% down), more flexible debt-to-income qualification, and more forgiving on recent credit events (short sale, bankruptcy, collections). The trade-off is mortgage insurance that stays for the life of the loan regardless of equity — making FHA more expensive over time for buyers who build equity
- Conventional loans are not government-backed — they follow Fannie Mae and Freddie Mac guidelines. Higher credit requirements (typically 620+ for 3% down, better rates at 740+) but private mortgage insurance that cancels automatically at 20% equity and can be removed by request at 20% LTV. More cost-effective over time for buyers with good credit who build equity
The Four Variables That Decide FHA vs Conventional
Variable 1 — Credit score
Credit score is the primary sorting variable for most San Antonio first-time buyers:
| Credit score range | FHA position | Conventional position | Decision |
| Below 580 | Available at 10% down | Not available at most lenders | FHA only option |
| 580–619 | 3.5% down, fully available | Limited availability, higher rates | FHA wins |
| 620–639 | 3.5% down, competitive | 3% down available but higher PMI rates | FHA usually wins — run both scenarios |
| 640–679 | Available but MI costs rising | 3% down, PMI cancellable at 20% | Run both — conventional often winning by year 7+ |
| 680–739 | Available but expensive long-term | 3% down, competitive PMI rates | Conventional wins at most price points |
| 740+ | Available but rarely optimal | Best rates, lowest PMI or avoid with 20% down | Conventional wins clearly |
The crossover point for most SA buyers is approximately 640–660: below this, FHA typically produces better approval odds and comparable costs; above this, conventional’s cancellable PMI makes it less expensive over a 5–10 year ownership period.
Variable 2 — Down payment amount
- 3.5% (FHA minimum): On a $270,000 SA-area home, that’s $9,450 — fully coverable with a TSAHC grant. FHA is the natural pairing for buyers using DPA programs targeting the 3.5% threshold
- 3% (conventional minimum — HomeReady/Home Possible): On a $270,000 home, $8,100 — slightly less than FHA. At 620+ credit, conventional 3% with a TSAHC grant produces a lower long-term cost than FHA 3.5% with a TSAHC grant because conventional PMI cancels at 20% equity and FHA MI runs for the life of the loan
- 5%–9.9% (conventional sweet spot): At 5% down with 640+ credit, conventional PMI rates improve meaningfully over the 3% entry. This is the tier where conventional’s long-term cost advantage over FHA becomes most pronounced
- 10%+ down: Conventional wins clearly — PMI rates are competitive and cancellation timeline is accelerated by the larger equity position
- 20% down: No PMI on conventional — FHA is never the right answer at 20% down
Variable 3 — How long you plan to own
This is the variable most buyers skip — and it’s decisive for buyers in the 620–679 credit range:
- FHA mortgage insurance premium: 0.55% annually for the life of a 30-year loan with less than 10% down. On a $270,000 loan, that’s approximately $1,485/year ($124/month) — every year, until you refinance or sell
- Conventional PMI at 640 credit, 3% down: Approximately 1.0%–1.3% annually initially — higher than FHA in year one — but cancels automatically at 78% LTV (approximately year 9 on normal amortization at San Antonio’s price point) or can be removed by request at 80% LTV
- The break-even point: For most SA buyers at 640–679 credit with 3%–5% down, conventional’s cumulative MI cost crosses below FHA’s cumulative MI cost somewhere between years 7 and 10. Buyers who plan to own fewer than 7 years may find FHA’s lower initial PMI rate more cost-effective. Buyers who plan to own 10+ years almost always pay less with conventional over the full period
Variable 4 — Property condition
FHA appraisers apply Minimum Property Requirements (MPRs) that conventional appraisers do not:
- Peeling paint on pre-1978 homes requires remediation before FHA loan approval
- Missing handrails, exposed wiring, inoperable windows, and health/safety concerns must be corrected before FHA closing
- Roof with less than 2 years remaining useful life may require repair or replacement before FHA approval
- Water quality testing required on well-water properties
The Leon Valley and older-stock Bexar County implication: In Leon Valley’s 1960s–1990s housing stock, FHA’s MPRs create a real constraint. Federal Pacific and Zinsco panels, deferred maintenance, and aging roofs that a conventional appraiser would note but not require repaired before closing become pre-condition requirements under FHA. Buyers targeting Leon Valley, older San Antonio sections, and pre-1980 construction should specifically discuss this with their agent and lender before defaulting to FHA. Conventional financing gives the buyer more leverage to negotiate repairs as credits rather than pre-closing requirements.
Side-by-Side Cost Comparison at San Antonio Price Points
$265,000 purchase — 640 credit score — 3.5% FHA vs 3% conventional
| Cost item | FHA 3.5% down | Conventional 3% down |
| Down payment | $9,275 | $7,950 |
| Upfront MIP / none | $4,394 (1.75%, financeable) | None |
| Loan amount | $260,119 (with financed MIP) | $257,050 |
| P&I at 6.5% (30yr) | ~$1,644/month | ~$1,624/month |
| Monthly MI | ~$119/month (0.55%, life of loan) | ~$215/month (1.0% initial, cancels ~yr 9) |
| Total monthly payment | ~$1,763/month | ~$1,839/month |
| Year 1 total cost | ~$21,156 + $9,275 down | ~$22,068 + $7,950 down |
| Year 10 cumulative MI paid | ~$14,280 (still paying) | ~$13,760 (likely cancelled by yr 9) |
| Year 15 cumulative MI paid | ~$21,420 (still paying) | ~$13,760 (no change — cancelled) |
Reading this table: Conventional costs more per month in the early years (higher PMI rate at 640 credit + 3% down). FHA costs more in aggregate over the life of ownership because the MI never cancels. The break-even is approximately year 9–10 for this specific scenario — buyers planning to own fewer than 9 years may find FHA’s early-year savings more relevant than the long-term conventional advantage.
$265,000 purchase — 700 credit score — same comparison
At 700 credit, conventional PMI drops to approximately 0.5%–0.7% annually — conventional wins in monthly cost AND long-term cost from year one. At 700+ credit, FHA is rarely the optimal loan product. A TSAHC grant covering the 3% conventional down payment at 700 credit produces the best available outcome for most non-VA, non-USDA San Antonio buyers.
The TSAHC + Loan Type Interaction
TSAHC’s grant programs work with both FHA and conventional — but the interaction matters:
- TSAHC + FHA: Grant covers the 3.5% FHA down payment entirely on most SA price points. Natural pairing for buyers with 580–639 credit who need FHA for approval. Long-term MI cost still applies — the grant eliminates the upfront barrier but not the ongoing expense
- TSAHC + Conventional (620+ credit): Grant covers the 3% conventional down payment. At 620+ credit, this combination produces lower long-term costs than TSAHC + FHA because conventional PMI cancels. For buyers with 620+ credit who want down payment assistance, TSAHC + conventional is typically the better long-term structure
- The TSAHC rate consideration: TSAHC loans carry program-specific interest rates that may be slightly above market rate for the strongest conventional borrowers. Compare TSAHC program rates against market conventional rates before choosing — some 740+ credit buyers with 5%+ down payment savings may find a market-rate conventional loan with no DPA produces lower total cost than a TSAHC program loan. Your TSAHC-approved lender runs this comparison as a standard step

When FHA Wins — Specific San Antonio Scenarios
- Credit score 580–619 with stable income and need to purchase in the next 6 months — FHA is often the only viable path
- Recent credit event (short sale, bankruptcy, job loss) within the past 2–3 years where conventional has waiting period requirements FHA doesn’t impose
- High debt-to-income ratio (43%–50% DTI range) where conventional’s stricter DTI limits don’t accommodate the payment — FHA’s manual underwrite path up to 50% DTI with compensating factors may qualify where conventional doesn’t
- Buyers planning to own fewer than 7 years in a market where appreciation will build equity faster than normal amortization — in that scenario, the lifetime MI concern is less relevant because the loan is being paid off or refinanced before the conventional break-even anyway
When Conventional Wins — Specific San Antonio Scenarios
- Credit score 640+ with any down payment amount — conventional’s cancellable PMI produces lower lifetime cost in almost every scenario above 7 years of ownership
- Older housing stock (Leon Valley, established Bexar County neighborhoods) where FHA’s MPR requirements create pre-closing repair obligations that reduce negotiating leverage
- Buyers targeting move-up communities (Stone Oak, Helotes, Alamo Ranch) where FHA’s loan limits may approach or be exceeded by the purchase price — verify current FHA loan limits for Bexar County before assuming FHA is available at your target price
- Buyers with 10%+ down payment savings — conventional’s PMI rates at 10%+ down are significantly lower than FHA’s flat 0.55%, and the cancellation timeline is much faster
- Investment-oriented buyers who will build equity aggressively (extra payments, fast appreciation) — conventional PMI can be removed by request at 80% LTV, potentially years ahead of normal amortization
Frequently Asked Questions: FHA vs Conventional in San Antonio
What credit score do I need for a conventional loan in San Antonio?
Most conventional lenders require a minimum 620 credit score for 3%–5% down payment conventional financing. Better rates begin at 680 and improve significantly at 720 and 740. Fannie Mae’s HomeReady program (3% down, 80% AMI income limit) and Freddie Mac’s Home Possible (3% down) are available at 620. For buyers at 580–619, FHA is typically the only viable path. Improving your score from 619 to 620 before applying can meaningfully change your loan options — ask your lender for a specific improvement plan if you’re close to a threshold.
Does FHA or conventional work better with TSAHC assistance in San Antonio?
At 580–619 credit, TSAHC + FHA is the most common viable path — FHA’s lower credit minimum is the deciding factor. At 620+ credit, TSAHC + conventional typically produces lower long-term cost because conventional PMI cancels at 20% equity and FHA MI runs for the life of the loan. The TSAHC grant covers either loan type’s minimum down payment. For buyers with 620+ credit, run both TSAHC + FHA and TSAHC + conventional scenarios with your lender before choosing. See our TSAHC Home Sweet Texas guide.
Can I get an FHA loan on older homes in Leon Valley or established San Antonio neighborhoods?
Yes — but FHA’s Minimum Property Requirements create pre-closing repair obligations on properties with certain condition issues. Federal Pacific and Zinsco panels, peeling paint on pre-1978 construction, roof with limited remaining life, and health/safety deficiencies must be remediated before FHA loan approval. This reduces your negotiating leverage — instead of requesting a repair credit from the seller, you’re often requiring the seller to complete the repair before closing. In Leon Valley’s older housing stock, this is a real constraint. Buyers targeting older properties should discuss FHA MPR implications with their agent before submitting an offer. See our Leon Valley buying guide.
Is FHA or conventional better for San Antonio first-time buyers in 2026?
In the current buyer-favorable market with 2%–3% seller concessions available across most communities, the question is less about which loan type and more about which credit score tier you’re in. At 580–619: FHA. At 620–639: run both scenarios — FHA typically wins in the near term, conventional in the long term. At 640+: conventional with a TSAHC grant covering the down payment produces the most cost-effective first-time buyer outcome at most SA price points. At 700+: conventional clearly wins. The seller concession availability in 2026 means closing costs are often covered regardless of loan type — removing that variable and leaving the ongoing MI cost comparison as the primary differentiator.
