Those looking to buy properties in Brooklyn often have the same first question: What are the current interest rates? The next question is usually about how these rates are determined.

Three main factors influence mortgage rates: the yield on 10-year Treasury bonds, the Federal Reserve's interest rate policy, and inflation trends. The 30-year fixed rate tends to be formed by adding a spread to the yield on 10-year Treasury bonds. The Fed's policy direction and market inflation expectations are reflected through the bond market.

The supply and demand in the MBS market also play a role. The level of rates offered by lenders varies depending on how much investors are buying mortgage-backed securities. On an individual level, credit score, DTI, and down payment ratio determine the actual interest rate.

• Credit Score (FICO)
• DTI Ratio
• Down Payment Amount
• Type and Term of Loan

So, what are the current rates? As of July 2026, the average 30-year fixed rate is in the mid to high 6 percent range, roughly between 6.6 and 6.8 percent. The 15-year fixed rate is lower, around 5.9 to 6.1 percent. This is a rough estimate based on public indicators like Freddie Mac's PMMS, and actual offers may vary by lender.

So, should you choose a fixed or an ARM? The 30-year fixed rate does not change throughout the term. An ARM offers a lower rate during the initial fixed period but is adjusted based on market rates afterward. If you plan to sell or refinance within a few years, an ARM might be worth considering.

How much difference does credit score make? Those with scores above 760 are likely to receive the most favorable rates. Scores between 700 and 759 tend to have slightly higher rates, while scores between 640 and 699 often see noticeably higher rates. Those below 620 may find it challenging to get conventional loan approval. There can be variations depending on the lender and product, so it's hard to make definitive statements.

In Brooklyn, there are significant price variations by neighborhood. Park Slope and Bensonhurst differ even in loan amounts. When deciding on a property, it's essential to check the appraisal value and property tax rate to accurately gauge monthly payments.

Korean households should check their credit reports at least one or two months before making an offer. It's advisable to lower credit card usage and refrain from taking out new loans or credit cards. Comparing estimates from multiple lenders is also recommended.

The future direction of interest rates is uncertain and depends on inflation indicators and Fed announcements. It's safer to monitor the monthly indicators when deciding on the timing of your loan.
