Common Questions About Choosing Between USDA and Conventional
Can I qualify for both and choose which one to use?
Yes! Many borrowers qualify for both options. We recommend getting pre-approved for both to compare actual rates, terms, and costs before deciding. Your specific situation, location, and financial goals will determine which is best.
Is conventional always faster than USDA?
Generally yes, conventional construction loans approve in 21-30 days versus 30-45 days for USDA due to additional USDA agency review. However, construction timeline itself is similar for both loan types once approved.
Can I use a USDA loan and pay extra down payment to avoid fees?
No, USDA loans don't accept down payments. The program is designed for 100% financing. If you have substantial down payment funds, conventional might be more cost-effective long-term despite higher rates.
What if my property is on the border of USDA-eligible area?
Use the USDA eligibility map to check your exact address. Even properties in suburban areas may qualify if they meet population density requirements. We can help verify eligibility for your specific lot.
Can I refinance from USDA to conventional later?
Yes, once your home is built and you have 20% equity, you can refinance to conventional to remove the USDA annual guarantee fee. This strategy helps some borrowers start with zero down then refinance to lower monthly costs.
