Mortgage rates can vary significantly from one borrower to another — even on the same day. While market conditions play a major role, lenders also evaluate several personal financial and property-related factors when determining your rate.
Understanding what affects mortgage pricing can help you better prepare for the homebuying or refinancing process and potentially secure more favorable loan terms.
In this guide, we’ll break down the six biggest factors that determine mortgage rates in 2026 and explain how lenders evaluate borrower risk.
Of all the different factors that can influence a borrower’s interest rate, there are six that rise to the top of the list. They include the following:
The type of property you purchase can directly affect your mortgage interest rate.
Different property types carry different levels of risk from a lender’s perspective. Because of this, pricing adjustments may apply depending on the home type and occupancy profile.
Generally, single-family primary residences receive the most favorable mortgage pricing, while higher-risk properties may come with slightly higher rates or additional requirements.
Examples include:
Condominiums, for example, can sometimes carry additional pricing adjustments on conventional loans when borrowers put less than 25% down. Multi-family and manufactured homes may also receive higher pricing adjustments due to increased historical default risk.
Property condition and marketability can also affect loan pricing in some scenarios.
How you plan to use the property is another major factor in mortgage pricing.
Lenders usually offer the best rates for primary residences because borrowers are statistically less likely to default on the home they live in full time.
Mortgage rates may be higher for:
Investment properties generally carry the highest rates because they represent greater financial risk during economic downturns.
For conforming loans backed by Fannie Mae or Freddie Mac, second homes can still qualify for competitive pricing. However, jumbo loan programs may require larger down payments, stronger reserves, and higher credit scores for vacation or investment properties.
Your down payment affects both your mortgage rate and your total loan costs.
A larger down payment lowers your loan-to-value ratio (LTV), which reduces lender risk and may improve pricing.
Many borrowers know that putting 20% down eliminates Private Mortgage Insurance (PMI), but additional pricing improvements can still occur beyond that threshold.
For many conventional loans, pricing may improve at:
A larger down payment may also help offset the impact of a lower credit score.
At the same time, many buyers today intentionally choose lower down payment options to preserve liquidity, maintain emergency reserves, or invest elsewhere.
Your credit score remains one of the biggest factors affecting mortgage rates.
Mortgage lenders typically review reports from:
Most lenders use the middle FICO score among the three bureaus. If there are multiple borrowers, lenders usually use the lowest middle score between all applicants.
In general:
For many conventional loans, the best pricing is commonly available around 740+ FICO scores, while some jumbo programs may provide additional improvements above 760 or 780.
Lenders also evaluate your broader credit profile, including:
Different mortgage programs come with different pricing structures.
Common loan types include:
Loan term also affects mortgage pricing.
For example, 15-year fixed mortgages often carry lower rates than 30-year fixed loans, though monthly payments are usually higher.
Adjustable-rate mortgages may initially offer lower rates compared to fixed-rate loans. However, rates can later adjust depending on market conditions and loan terms.
In today’s market, ARMs have regained popularity among borrowers who expect to refinance, relocate, or pay off the loan before future adjustments occur. Sammamish Mortgage can help you assess whether a shorter loan term is right for your specific financial situation.
Mortgage rates are also heavily influenced by broader economic and market conditions.
Factors that impact mortgage pricing include:
While the Federal Reserve does not directly control mortgage rates, its policies strongly influence borrowing costs across the economy.
In recent years, mortgage rates have experienced significantly more volatility due to inflation concerns and changing economic conditions.
Because of this, timing can have a major impact on the rate you ultimately receive.
Other factors lenders may evaluate include:
Every borrower scenario is unique, which is why personalized rate quotes are usually much more accurate than advertised national averages.
Borrowers may be able to improve mortgage pricing by:

The main factors include property type, occupancy type, down payment amount, credit score, loan type and term, and overall market conditions.
Yes. Single-family primary residences often receive the most favorable pricing, while condos, multi-family properties, and manufactured homes may come with higher pricing adjustments.
Lenders usually offer the best rates for primary residences because borrowers are less likely to default on the home they live in full time. Second homes and investment properties often have higher rates.
A larger down payment lowers the loan-to-value ratio, which reduces lender risk and can improve pricing. It may also help offset the impact of a lower credit score.
Credit score is one of the most important pricing factors. Higher scores often qualify for lower rates, while lower scores may lead to higher pricing adjustments or fewer loan options.
Mortgage lenders typically review credit reports from Experian, Equifax, and TransUnion and use the middle FICO score. With multiple borrowers, lenders often use the lowest middle score among all applicants.
Yes. Conventional, FHA, VA, USDA, jumbo, and adjustable-rate mortgages each have different pricing structures based on program guidelines and borrower risk.
Often, yes. Fifteen-year fixed mortgages commonly have lower rates than 30-year fixed loans, although the monthly payments are usually higher.
Mortgage rates are influenced by inflation, Federal Reserve policy, bond market performance, employment data, economic growth, and investor demand for mortgage-backed securities.
Borrowers may improve pricing by increasing their credit score, lowering debt, making a larger down payment, improving cash reserves, comparing loan options, choosing a shorter term, and locking at an appropriate time.
