Buying a Home in San Marcos

Buying in San Marcos means the same statewide Texas closing-cost and process rules as anywhere else in the state, layered onto two genuinely local due-diligence items: flash-flood exposure from the San Marcos River, Blanco River, and Purgatory Creek, and the same regional hail risk that affects the rest of Central Texas.

Market Conditions and Typical Closing Costs

With inventory running close to a balanced 4.9 months of supply (see the housing-market topic page), San Marcos in 2026 offers real, if modest, buyer negotiating room rather than a hot seller's market. Texas buyers typically pay 2%-6% of the purchase price in closing costs (lender fees, title insurance, appraisal, recording fees, prepaid escrow), per multiple Texas mortgage-industry closing-cost guides -- on the roughly $340,000 median-priced San Marcos home, that is approximately $6,800 to $20,400. Texas levies no real estate transfer tax, a real if modest savings relative to many other states.

Flood Zone and Creek/River Proximity: The Most Important San Marcos-Specific Check

Confirm the FEMA flood zone designation for any specific property before writing an offer, and specifically ask about proximity to the San Marcos River, the Blanco River, and Purgatory Creek -- the three primary flood sources documented for the city (see the insurance-hazard-costs topic page for the full history, including the catastrophic May 2015 Memorial Day flood). This is not a boilerplate check carried over from a coastal-market template: San Marcos has a real, specific, well-documented flood history, and flood risk here varies meaningfully by specific address rather than applying uniformly across the city.

Roof and Hail Inspection

San Marcos sits within the same Central Texas hail belt affecting Austin and the broader Hill Country, and roof condition affects homeowners insurance pricing here the same way it does across the region (see the insurance-hazard-costs topic page). Beyond a standard general inspection, ask about roof age, material class, and any prior hail-damage claims history on the property.

Real Estate Agent Compensation Norms

As in most U.S. markets following the 2024 National Association of Realtors settlement, buyer-agent compensation in Texas is now more commonly negotiated directly between buyer and buyer's agent rather than assumed to be paid entirely by the seller -- get compensation terms in writing before touring homes. This changed nationally, not specifically in San Marcos, but applies here the same as anywhere else in Texas.
