Can I use a conventional loan to buy an investment property or second home in Washington?

Yes. Conventional loans work for primary residences, second homes, and investment properties. Investment properties require at least 15–25% down and carry slightly higher rates than primary residence loans. Second homes typically need 10% down and must be in a location that makes sense as a vacation or seasonal property. If you're buying an investment property and want to qualify off rental income instead of your personal income, a DSCR loan may be a better fit.
