There are cases where a loan is denied at the last minute even after receiving pre-approval. Recently, I saw an example where someone had saved enough for a down payment but suddenly increased their DTI by purchasing a new car on credit just before closing. If you are looking for a home in Portland, it is essential to check this aspect before considering the amount of your down payment.

So, how much should you prepare? According to Redfin, as of May 2026, the median home price in Portland is $535,000. Since this is higher than the national average, the difference in amounts based on down payment percentages can be significant.

If you calculate using the FHA minimum requirement of 3.5%, you would need $18,725, and if your credit score is below 580, you would need 10%, which is $53,500. If you prepare for a conventional loan at 5%, you would need $26,750, and if you cover 20%, which is $107,000, you can proceed without PMI.

So, which option is better? Putting down 20% lowers your monthly payments and eliminates PMI, but it ties up a large sum of money for a longer time. On the other hand, starting with 3.5% or 5% allows for a quicker closing, but you need to consider that PMI will be added monthly.

Additionally, property taxes in Oregon are a variable to consider. The average effective tax rate in Oregon is reported to be around 0.81% according to the Tax Foundation (as of 2026). If you are coming from California or Texas, be aware that the assessment methods vary by county, which may result in actual bill amounts differing from your expectations.

If preparing a down payment feels burdensome, it may be worth checking out the down payment assistance programs from Oregon Housing and Community Services. These are operated through local organizations and are aimed at first-time homebuyers or first-generation buyers with an income at or below 100% of the area median income. The maximum assistance varies by program, but there are cases where support is provided for up to 20% of the purchase price or $60,000, whichever is less. Before applying, housing education and a consultation with a counselor are mandatory.

Such assistance can be a key factor in determining loan approval. There are instances where applicants who could not meet the approval threshold due to insufficient down payment funds were able to qualify by using assistance to supplement their own funds.

So, how can you increase your approval rate? As of July 2026, the 30-year fixed rate for those with a credit score above 780 is 6.59%, 6.66% for those in the 760 range, 6.75% for the 740 range, and 6.91% for the 700 range (themortgagereports.com). Just raising your credit score by one bracket can change both your monthly payment and approval chances.

What should your DTI be? For Qualified Mortgages, the backend DTI should be below 43%, while conventional loans typically range between 36% and 45%. The ideal frontend DTI, which only considers housing costs, is below 28% (Consumer Financial Protection Bureau). If you have student loans or credit card debt, it is advantageous to reduce those balances before closing.

Is the source of your down payment also a point of scrutiny? Yes. If you are using funds gifted from parents or relatives for your down payment, you will need to submit a gift letter to the lender, and it is safer to have those funds reflected in your account at least two months before closing. If a large amount is deposited suddenly, you may be asked to explain the source, which can delay approval.

If you are competing for a property, should you also consider situations where the appraised value is less than the offer? Yes. In areas like Portland, where properties sell quickly, you may need to cover this difference in cash, and you should factor in that you might use some of your down payment funds for this purpose.

Pre-approval not only clarifies your budget but also gives you an advantage in offer competitions. It is wise to have your income documentation organized in advance, and during the review process, it is best to avoid taking out new loans or changing jobs. Lenders will recheck your credit and income status right up to closing.

You should also prepare reserve funds. Having enough to cover several months of payments after closing is an important consideration during the review process. In school districts where many Korean families reside, prices can be high, so when planning your down payment, consider the school district as well, but be sure to verify the assigned school before purchasing.
