New construction homes along the I-35 corridor between Austin and San Antonio are offering interest rates as low as 4.25 percent through builder-affiliated lenders, while resale buyers face rates in the high fives to low sixes. This significant gap is reshaping how buyers make decisions in the New Braunfels, Texas market. On a $350,000 home, the difference can mean several hundred dollars less per month, making new construction increasingly attractive.
Yitzchak Pierson, a licensed real estate broker specializing in new construction along the Austin-San Antonio corridor, notes that the rate conversation often becomes the first topic in buyer consultations. However, he cautions that the builder-offered rate buy-downs come with conditions. To access the promoted rate, buyers typically must use the builder’s preferred mortgage company, which operates at high volume and may not provide independent advice. A smarter approach, Pierson suggests, is to get pre-approved with an outside lender first. A mortgage broker can shop multiple products and give buyers a real baseline, allowing them to evaluate the builder’s offer on its actual merits. Sometimes the buy-down wins, but sometimes an outside lender paired with better pricing or different incentives comes out ahead.
Beyond the rate, buyers often overlook other negotiating opportunities. Pierson cites a recent buyer who forwent the builder’s rate buy-down entirely. Instead, using an outside lender, they negotiated a lower purchase price, $10,000 in closing costs, and had the builder include a refrigerator, washer, dryer, irrigation system, blinds, and a garage door opener. While the interest rate was slightly higher, the overall deal was better for that specific buyer’s situation. This illustrates the importance of understanding the full picture rather than fixating on one number.
The holding period also plays a critical role in the rate decision. For buyers planning to stay two to three years, the purchase price and negotiated incentives matter more than the interest rate. A lower purchase price affects property taxes and resale potential. For long-term primary residences or investment properties held for decades, locking in the lowest possible rate becomes a higher priority. Pierson emphasizes that the right answer depends on individual goals, not on the builder’s promotion of the month.
Buyers who walk into a new construction sales office without preparation are at a disadvantage. Before engaging with a builder’s financing team, buyers should know their pre-approved amount with an outside lender, understand the builder’s incentive requirements, and clarify their own priorities—whether rate, price, closing costs, or upgrades. Builders have flexibility, especially on completed inventory homes that cost them money every month they sit unsold. This creates negotiating room for prepared buyers.
