Build vs. Buy in McAllen in 2026: The Honest Answer

This is the question every RGV family asks. Here’s our honest, non salesy take:

🏗️ Build with South Texas Builders

• Exactly the layout your family needs

• Brand new systems, zero deferred maintenance

• Builder’s warranty (1 yr workmanship, 10 yr structural)

• Open cell spray foam insulation = lower utility bills

• Post tension slab, engineered for RGV soils

• Current 2024 Texas energy codes

• Free blueprints, transparent regional pricing

• 7 to 12 months until move in, depending on plan and region

🏠 Buy an Existing Home in McAllen

• Move in within 30 to 60 days of closing

• Established neighborhood, mature trees

• Older HVAC, roof, plumbing, replace when?

• Layout is fixed, must renovate to change

• Foundation issues common in older RGV homes

• Built to older, less efficient energy codes

• Hidden inspection surprises after closing

• Limited inventory in desirable RGV areas

📊Bottom LineExisting homes in McAllen currently sell between $160,000 and $280,000 for a modest 3 bedroom home. A new 1,800 sq ft custom home built to our Fully Loaded standard runs $207,000 to $216,000 in the McAllen/RGV core, squarely inside that same range, but brand new, under warranty, with spray foam insulation throughout, and every finish chosen by you instead of a previous owner. The only real trade off is time. If you can wait 7 to 12 months, building almost always wins.

By 2025, Rolando Peña and Cristo Calderón had joined the team, and the company rebranded as South Texas Builders to reflect its growth across the RGV.

How much more does Cameron County cost than McAllen?

Are permits included in the construction price?

Yes, all permits are included in every South Texas Builders package, with one exception: windstorm permits, where applicable depending on your zone. We manage the entire permit process on your behalf with the City of McAllen, Edinburg, Brownsville, or your specific municipality. This is a significant time and stress savings for our clients.

Can I build with a VA loan in the Rio Grande Valley?

Absolutely, South Texas Builders is proud to work with VA construction loans for eligible veterans, active duty service members, and surviving spouses. VA loans require zero down payment and carry no private mortgage insurance (PMI), making them one of the best construction financing options available. You will need your Certificate of Eligibility (COE), which your lender can help you obtain. Our team can connect you with a trusted local VA lender the same day you call: ****.

Does a one time close loan save money?

Yes, Construction to Perm (one time close) loans typically save $2,000 to $6,000 in closing costs versus doing a separate construction loan and permanent mortgage. You also lock in your rate once and avoid a second round of underwriting and paperwork.

What does open cell spray foam insulation mean and why does it matter?

Open cell spray foam insulation is a premium insulation material that expands to fill every gap in your walls, ceiling, and attic, creating an airtight thermal envelope that standard batt insulation cannot match. In the South Texas climate, where summer temperatures regularly exceed 100°F, this translates directly into meaningfully lower air conditioning costs over the life of your home. It also reduces noise transmission, improves indoor air quality, and adds structural rigidity. Open cell spray foam is included throughout our Fully Loaded builds at no additional charge, one of the most valuable features of choosing South Texas Builders.
