If there’s one belief keeping more qualified San Antonio renters out of homeownership than anything else, it’s this: the idea that you need 20% down to buy a house. It’s not true, and it hasn’t been true for a long time — but it’s still the first thing almost every first-time buyer tells me when we sit down for a consult.
Where the 20% Number Actually Comes From
The 20% figure isn’t a rule — it’s a threshold for avoiding private mortgage insurance (PMI) on a conventional loan. That’s it. It was never a minimum requirement to buy, and for most first-time buyers in San Antonio, it’s not even the most realistic path.
What You Actually Need, Program by Program
- Conventional: as low as 3% down
- FHA: as low as 3.5% down
- USDA: 0% down in eligible areas just outside San Antonio’s urban core
- VA: 0% down for active duty, veterans, and eligible spouses
And that’s before layering in San Antonio-specific down payment assistance — TSAHC, TDHCA, SAHA, HIP 80, HIP 120, and MCC programs can cover some or all of what’s left. Most of my first-time buyer clients close with far less cash out of pocket than they expected walking in.
Why This Myth Persists
Part of it is outdated advice passed down from relatives who bought decades ago under different lending standards. Part of it is that no one ever sits first-time buyers down and walks through the actual math for their specific situation. That’s the gap I built my business around closing.
What This Means for Your Monthly Payment
A smaller down payment does mean a larger loan amount, which affects your monthly principal and interest — a real tradeoff worth understanding, not a reason to rule yourself out. The right program balances what you have today against a payment you’re comfortable with long-term.
Frequently Asked Questions
Correct. Most first-time buyers close with 3% down or less once down payment assistance is applied — some VA buyers close with $0 down.
Not inherently. Approval depends on your full financial picture — credit, income, and debt — not just your down payment size.
