Watching mortgage rates tick up and wondering if buying in San Marcos still makes sense? You are not alone. When rates rise, your monthly payment and price range can shift quickly, and it can feel hard to know what to do next. In this guide, you will see how rate moves affect payments and buying power, how local San Marcos and Hays County trends shape your options, and practical strategies to keep your purchase on track. Let’s dive in.
How higher rates change payments
When you take out a mortgage, your monthly principal and interest payment is determined by the loan amount, the interest rate, and the term. If the rate rises, the monthly payment for the same loan amount goes up. Most buyers set a monthly budget first, so higher rates usually mean you qualify for a smaller loan.
The simple payment math
- Mortgage pros often use a quick guide called a “payment per $1,000.” For a 30-year fixed loan, the approximate principal and interest per $1,000 borrowed is:
- 4.00% → about $4.774 per $1,000
- 5.00% → about $5.368 per $1,000
- 6.00% → about $5.996 per $1,000
- 7.00% → about $6.653 per $1,000
- Multiply the factor by your loan amount in thousands to estimate monthly principal and interest.
- Remember, your full monthly housing cost also includes property taxes, homeowners insurance, any HOA fees, and mortgage insurance if applicable.
Why small changes matter
Even a 1 percentage point change in rate can raise monthly principal and interest by roughly 10 to 13 percent on the same loan size. If you are making a smaller down payment, your loan is larger, so the dollar impact is bigger. That shift can move you down a price band or out of certain neighborhoods you were considering.
What rising rates mean in San Marcos
San Marcos sits between Austin and San Antonio and is shaped by several demand drivers. You will see owner-occupants, student rental investors, and commuters all in the mix. These different buyer types react to rising rates in different ways.
Demand drivers you will see locally
- A strong university presence supports steady rental demand near campus and along key corridors.
- Commuters moving between Austin and San Antonio look to San Marcos for relative value and access to both metros.
- Population and employment growth in Hays County have supported housing demand over time.
Supply and inventory patterns
- Inventory can be tight in certain neighborhoods, which slows down price adjustments when rates rise. In those pockets, sellers may keep some pricing power.
- Where inventory is more ample, buyers may gain leverage and see more room for negotiation.
- New construction adds options, and builders sometimes use incentives to keep monthly costs competitive.
How financing choices affect you
- Conventional loans are common in Texas, with FHA and VA also used by first-time buyers and veterans.
- A larger down payment reduces your loan size and rate sensitivity.
- Cash buyers and investors are less affected by higher rates and can remain active even when financed buyers pull back.

Monthly P&I examples
$300,000 purchase price (loan about $240,000)
- 4.0% → about $1,146 per month
- 5.0% → about $1,288 per month
- 6.0% → about $1,439 per month
- 7.0% → about $1,597 per month
$450,000 purchase price (loan about $360,000)
- 4.0% → about $1,719 per month
- 5.0% → about $1,933 per month
- 6.0% → about $2,158 per month
- 7.0% → about $2,395 per month
$650,000 purchase price (loan about $520,000)
- 4.0% → about $2,483 per month
- 5.0% → about $2,792 per month
- 6.0% → about $3,118 per month
- 7.0% → about $3,460 per month
Buying power with a fixed budget
Here is another way to see it. Say you cap principal and interest at about $1,800 per month. At roughly 4.0 percent, that supports a loan around $377,000. At roughly 6.0 percent, the same monthly budget supports about $300,000. That is a decrease of about $77,000 in loan capacity, or about 20 percent less buying power.
Negotiation and strategy in today’s market
When rates rise, some buyers pause, which can open doors for those who are prepared. Your strategy should reflect the submarket you are targeting in San Marcos.
Concessions sellers may offer
- Seller-paid closing cost credits to help you cover upfront costs.
- Temporary or permanent rate buydowns, where the seller pays points to lower your interest rate for a period or for the life of the loan.
- Flexible timing, repair allowances, or a home warranty to reduce friction and perceived risk.
Smart buyer moves now
- Get preapproved and, if possible, lock a rate. This shows strength and protects you from near-term rate moves while you shop.
- Consider a larger down payment if you can. A smaller loan reduces your monthly sensitivity to rates.
- Ask for a rate buydown or seller credit instead of a list-price cut in segments where sellers want to keep headline pricing intact.
- Compare lender quotes on points versus payment. Paying points can make sense if you plan to stay in the home long term.
- Move quickly on well-priced listings, and use inspection and appraisal contingencies thoughtfully where inventory allows.
Local nuances that shape your options
- Areas near campus and along transit corridors often see steady investor interest. Even when rates rise, that segment can stay active.
- Submarkets favored by commuters may shift as regional affordability changes, especially if conditions in the Austin area tighten or loosen.
- Builders sometimes offer rate buydowns or closing credits that can make new construction competitive with resale options.
Steps to stay on track in Hays County
- Clarify your monthly comfort zone, including taxes, insurance, HOA fees, and utilities. Do not look at principal and interest alone.
- Map your must-haves to two or three price bands so you can pivot if rates change.
- Ask your lender for two quotes: one without points and one with a buydown, plus any temporary buydown options.
- In your target neighborhoods, watch days on market and price reductions. Longer days on market can signal room for concessions.
- If you are on a tight timeline, focus on homes with recent updates and clean inspection histories to reduce surprises during escrow.
Should you wait or buy now?
There is no one-size-fits-all answer. Rates are only one part of the equation. Inventory, your timeline, and the right home all matter. A clear plan that compares a few realistic scenarios can help you decide. The key is to control what you can: your budget, your financing options, and your negotiation strategy.
