Tips for Staying On Budget
After building hundreds of homes in Central Texas, here are our top recommendations:
1. Build in a Contingency
Always include a 10-15% contingency in your budget. Unexpected costs will arise—whether it's rock removal during excavation or a change order you didn't anticipate.
2. Prioritize What Matters Most
Decide upfront which features are non-negotiable and where you're willing to compromise. Custom cabinets might be a must-have, but you could save on light fixtures.
3. Choose a Fixed-Price Contract
Whenever possible, work with a builder who offers fixed-price contracts. This protects you from cost overruns and provides certainty in your budget.
4. Think Long-Term
Investing in energy-efficient windows, proper insulation, and a high-efficiency HVAC system will save you thousands in utility costs over the life of your home.
Financing Your Custom Home Build
Building a custom home typically requires a construction loan that converts to a traditional mortgage upon completion. Here's what lenders generally require:
- Down payment: 20-25% of total project cost
- Credit score: 680+ preferred
- Debt-to-income ratio: Below 43%
- Cash reserves: 6-12 months of payments
Working with a lender experienced in construction loans can make the process much smoother. We're happy to recommend trusted partners we've worked with on past projects.
