How to Buy a Home in San Antonio With a Conventional Loan: A Step-by-Step Playbook

How do you use a conventional loan to buy a home in San Antonio, Texas—step by step?
A conventional loan can be a great fit when you want flexible terms and a competitive offer—especially in a market where timing, appraisal strategy, and documentation can make or break your closing.

Why conventional loans matter in today’s San Antonio market

San Antonio has been moving at a more measured pace, which is good news for buyers who show up prepared. Zillow’s market snapshot for San Antonio showed a median sale price around $274,917 (Nov 2025) and 61 median days to pending (Dec 2025), with 63.9% of sales closing under list price and a 0.982 median sale-to-list ratio. (Zillow)

Redfin’s San Antonio market data also pointed to a slower cadence, reporting a December 2025 median sale price of about $264,590 and 82 days on market on average. (Redfin)

SABOR’s November 2025 press release echoed that trend locally, noting homes spending an average of 86 days on market. (Sabor)

What this means for you: a conventional loan isn’t just a loan type—it’s a way to write a cleaner offer, reduce surprises in underwriting, and negotiate from a position of strength.

Step 1: Get pre-approved the right way (and understand your timelines)

Pre-approval is where your lender reviews your credit, income, assets, and debt to estimate what you can borrow—and more importantly, what you can close. This is different from pre-qualification, which is usually a lighter, less documented estimate.

Two timing rules are especially helpful to know upfront:

• Loan Estimate: Once you apply, the lender must send a Loan Estimate within three business days. (Consumer Financial Protection Bureau)
• Closing Disclosure: You must receive a Closing Disclosure at least three business days before closing, giving you time to review final numbers. (Consumer Financial Protection Bureau)

How I help here: As your Realtor, I’m looking ahead to the contract timeline you’ll need to hit—so your pre-approval isn’t just “good enough,” it’s built to withstand underwriting and appraisal.

Step 2: Know the three approval drivers underwriters focus on

Credit

Many lenders commonly look for a 620+ credit score for conventional financing, though approval can vary by lender and overall file strength. (Experian)

Also worth noting: Fannie Mae has updated Desktop Underwriter so that, for certain submissions, DU no longer applies a minimum credit score requirement and instead evaluates risk using a broader assessment. (Fannie Mae)
(That doesn’t mean “score doesn’t matter”—it means your full profile and documentation quality matter even more.)

Down payment and PMI strategy

Some conventional programs allow as low as 3% down for eligible buyers (including certain first-time-buyer options). (Fannie Mae)

If you’re under 20% down, you’ll typically see private mortgage insurance (PMI). The good news: you have the right to request PMI cancellation when your balance is scheduled to reach 80% of the home’s original value (if you meet the requirements). (Consumer Financial Protection Bureau)

A practical strategy is to treat PMI as a temporary tool—use it to buy sooner, then plan how you’ll eliminate it (extra principal payments, value growth, or a future refinance if rates allow).

Debt-to-income and documentation

Underwriting is basically the lender verifying that your story matches your paperwork. Expect to provide pay stubs, W-2s (or tax returns if self-employed), bank statements, and explanations for any big deposits.

One of the simplest ways to keep underwriting smooth is to avoid major changes mid-transaction—new credit cards, big purchases, job changes, or moving large sums without documentation.

Step 3: Build your home search around payment reality, not just purchase price

It’s easy to shop based on what you’re approved for. It’s smarter to shop based on what feels comfortable month-to-month.

A conventional payment usually includes:

• Principal + interest
• Property taxes
• Homeowners insurance
• (Possibly) HOA dues
• (Possibly) PMI

In Texas, property taxes can be a meaningful part of your monthly payment, so planning early matters. Texas’ homestead exemption rules can also impact your taxable value; the Texas Comptroller explains the $140,000 mandatory homestead exemption for school district taxes for eligible homeowners. (Texas Comptroller)

How I help here: I’ll help you compare neighborhoods and price points through the lens of monthly payment, not just list price—so you don’t fall in love with a home that stretches your budget in a way you’ll feel later.

Step 4: Write an offer that fits today’s San Antonio leverage points

Because a large share of San Antonio homes have been closing under list price, you may have room to negotiate—especially if your offer is clean and well-supported. (Zillow)

That doesn’t mean you always go low. It means your offer should match the home’s leverage profile: days on market, seller motivation, and how likely the appraisal is to support the price.

Here are a few offer terms that often matter with conventional financing:

• A strong pre-approval letter with updated documentation
• Clear (and realistic) closing timeline
• A thoughtful appraisal plan (especially if competing)
• Inspection terms that protect you without creating chaos

This is where strategy beats guesswork. The goal is to get accepted and get to the finish line.

Step 5: Appraisal and underwriting—where most deals feel stressful

Appraisal

The appraisal is the lender’s value check. If the appraisal comes in low, you generally have a few paths: renegotiate the price, adjust terms, bring additional cash to cover a gap, or dispute with better comparable sales (sometimes worth trying, sometimes not).

The best time to think about appraisal risk is before you write the offer—not after the report arrives.

Underwriting

Underwriting is the “verify everything” stage: employment verification, bank/asset review, title work, appraisal review, and any lender conditions.

If you want fewer last-minute issues, aim for:

1. clean documentation early, and
2. fast responses when the lender asks for clarification.

Step 6: Texas disclosures and what you should actually read

In Texas, sellers of many previously occupied single-family residences use the Seller’s Disclosure Notice, which aligns with requirements in Section 5.008 of the Texas Property Code and the TREC form guidance. (TREC)

This isn’t “just paperwork.” It’s a roadmap for what to investigate during your inspection period. If something is disclosed, it doesn’t always mean “don’t buy”—but it does mean “verify and understand.”

Step 7: Rate context—why preparation can beat waiting

Rates move, and headlines can be noisy. The practical takeaway is that you can’t control the market, but you can control readiness.

Recent reporting has shown 30-year fixed rates hovering around the low 6% range in early 2026, depending on the week and source. (Wall Street Journal)
Even small rate shifts can change purchasing power, which is why a strong pre-approval and flexible home search criteria can keep you in control.

Final takeaway

Buying in San Antonio with a conventional loan gets dramatically easier when you treat it like a process, not a leap of faith. The market has been moving at a steadier pace—with longer days on market and a meaningful share of homes closing under list—so your advantage comes from being prepared, strategic, and responsive from pre-approval through closing.
