20% down eliminates private mortgage insurance and may lower your interest rate.

Conventional loans are mortgage products that are not insured or guaranteed by the federal government. In Oregon, the down‑payment rules for these loans follow the same national guidelines, but state‑specific assistance programs can help borrowers meet the required amount.

Basic Down Payment Rules

For a conventional loan, lenders usually require a minimum of 3% of the home’s purchase price if you have a strong credit profile and are willing to pay private mortgage insurance (PMI). Many lenders set the floor at 5% for borrowers who do not qualify for the lowest‑down‑payment tier. The exact percentage can vary based on your credit score, debt‑to‑income ratio, and the loan amount.

How Private Mortgage Insurance Works

When you put down less than 20% of the home’s value, lenders typically require PMI to protect themselves against default risk. PMI is an extra monthly cost that stays in place until your equity reaches 20% of the property’s original value. Paying 20% or more upfront removes the need for PMI, which can lower your overall monthly payment.

Oregon‑Specific Assistance Options

Oregon’s Housing and Community Services (OHCS) offers down‑payment assistance grants and low‑interest loans that can be combined with a conventional mortgage. These programs are aimed at first‑time homebuyers and moderate‑income families, and they often require completion of a home‑buyer education course. While the assistance itself isn’t a loan requirement, it can help you meet the 3%–5% down‑payment threshold.

Why Down Payment Size Matters

Higher equity reduces lender risk, which can lead to better loan terms.
Putting down at least 20% eliminates PMI, saving you hundreds of dollars each month.
A larger down payment can improve your loan‑to‑value (LTV) ratio, making you a more attractive borrower.

FAQ

Can I use Oregon down‑payment assistance programs with a conventional loan?

Yes. Many state programs, such as those offered by Oregon Housing and Community Services, provide grants or low‑interest loans that can be combined with a conventional mortgage, as long as you meet the program’s eligibility criteria.

What happens if I put down less than 20%?

If your down payment is below 20%, the lender will usually require private mortgage insurance (PMI). You will pay this insurance until your equity reaches 20% of the home’s original purchase price.

Do I need private mortgage insurance if I put down 3%?

Yes. A 3% down payment triggers the PMI requirement, which protects the lender because the loan‑to‑value ratio is higher.

How does my credit score affect the down‑payment requirement?

Higher credit scores can qualify you for the 3% minimum down payment, while lower scores may require a larger down payment (often 5% or more) to offset perceived risk.

Are there any Oregon‑specific rules about who can close a mortgage?

Oregon allows both title companies and attorneys to conduct closings. The choice often depends on the lender’s preference and the buyer’s comfort level, but there is no statewide requirement to use an attorney.
