Home Addition vs. Moving in San Antonio TX — Which Makes More Sense?

Your family is growing. Your house isn't. Every San Antonio homeowner faces this decision at some point: add on to your current home, or sell and move somewhere bigger? Roy De Luna of MrRoyLLC has helped dozens of families work through this exact question. Here's an honest breakdown.

The Cost to Move in San Antonio

People underestimate the true cost of selling and buying in San Antonio's market. Between realtor commissions (5–6%), closing costs (2–3% on each side), moving costs, and the premium you'll pay to upsize in the current market, most families spend $35,000–$60,000 just in transaction costs — before they ever buy a stick of new furniture.

The Cost to Add On

Room additions in San Antonio run $150–$250 per square foot depending on complexity. A 400 sq ft primary bedroom addition with a bathroom runs $60,000–$100,000. A garage conversion or bedroom addition over a garage runs $25,000–$50,000. A modular addition (sunroom, enclosed patio) can start at $15,000.

When Adding On Makes More Sense

• You love your neighborhood and your neighbors
• Your kids are in a specific school district you don't want to leave
• Your home's lot has room to build
• You have equity to finance the project
• Current interest rates make upsizing a new mortgage painful

When Moving Makes More Sense

• Your lot has no room to expand
• Your current home has fundamental layout problems no addition can fix
• The neighborhood is changing in a direction you don't like
