In the high 6% range. As of mid-2026, the first number you encounter when looking for a 30-year fixed mortgage in Boise is roughly in this range. However, this number is just the market average; the actual rate I receive can vary significantly based on my credit score and loan conditions.

Let's first clarify where this number comes from. The key factors that influence mortgage rates are largely as follows:

• 10-year Treasury yield: serves as a benchmark for long-term fixed rates
• Federal Reserve's benchmark interest rate and monetary policy direction
• Inflation indicators: the higher the price pressure, the more likely long-term rates will rise
• Supply and demand conditions in the MBS (Mortgage-Backed Securities) market
• Personal credit score, DTI, down payment ratio

Among these, the first four are macro variables that apply nationwide, while the last factors—credit score, DTI, and down payment—are applied differently for each individual. This is why two people can receive different final rates even when applying for a loan on the same day.

15-year fixed rates tend to be about 0.5 to 0.75 percentage points lower than 30-year rates. While the monthly payment is higher, it can significantly reduce total interest costs, making it worth considering for households with stable income and sufficient monthly payment capacity.

ARM (Adjustable Rate Mortgage) products often offer lower initial rates compared to fixed-rate loans for the first few years, typically structured as 5/1 or 7/1. However, there is a risk that rates may rise after the adjustment period depending on market conditions. If you do not have a clear plan for short-term residency or refinancing, it is advisable to approach this option cautiously.

The difference in rates based on credit scores can be quite noticeable. There can be a significant gap between the 760+ range and the 620- range, which directly affects not only loan approval but also monthly payments. Since the exact figures vary by lender, it is more accurate to obtain pre-approval estimates and compare them directly.

In Boise, the experience can vary significantly by neighborhood. Areas with older homes, like North End, have limited inventory and less room for price negotiation, while newly developed areas like Meridian or Eagle may have more inventory, which can work to your advantage in negotiating loan terms. It is advisable to consider these regional differences when obtaining loan pre-approval.

If you are a Korean household, it is recommended to aim for a down payment ratio of over 20% to avoid PMI costs, and to compare estimates from at least three or four lenders. Even with the same credit score, there can be considerable differences in rates and closing costs offered by different lenders.

Rates may move gradually in the future depending on inflation trends and Federal Reserve policies. If you are planning to take out a loan, it is advisable to periodically check the latest figures through reliable sources like Freddie Mac's PMMS.
