What is a Conventional Loan in Oregon?
A conventional loan is a residential mortgage not backed by the federal government (such as FHA, VA, or USDA). Instead, it adheres to guidelines set by Fannie Mae and Freddie Mac, offering greater flexibility in property types, down payments, and removable mortgage insurance.
What is Required to Qualify in Oregon?
Conventional guidelines are standard throughout Oregon. While they require slightly higher credit benchmarks than government options, they reward qualified borrowers with lower ongoing monthly borrowing costs.
