Rockville is conveniently located in the heart of Montgomery County, but that also means housing prices are quite high. For those wondering whether to buy now with high interest rates or wait a bit longer, we always provide insights from both sides. Ultimately, the decision depends on each family's unique situation.

The most fundamental aspect of understanding mortgage rates is the yield on 10-year U.S. Treasury bonds. The 30-year fixed mortgage rate is calculated by adding a spread to this bond yield, meaning that movements in the bond market are reflected in mortgage rates with a lag. Additionally, the Federal Reserve's decisions on interest rates and market expectations regarding future policy directions have a significant impact.

Inflation indicators are also crucial. If inflation rates are higher than expected, bond investors will demand higher yields, which leads to an increase in mortgage rates. Conversely, if inflation shows signs of stabilizing, expectations for lower rates may grow. Alongside this, the supply and demand situation in the MBS (Mortgage-Backed Securities) market directly affects interest rates.

As of 2026, based on Freddie Mac's PMMS, the average rate for a 30-year fixed mortgage is observed to be in the mid to high 6% range. The 15-year fixed mortgage tends to move between the high 5% and low 6% range. While the monthly payment burden is lighter for the 30-year fixed, the total interest cost is definitely more favorable for the 15-year fixed.

Both ARM (Adjustable Rate Mortgages) and fixed-rate mortgages have distinct advantages and disadvantages. ARM offers lower rates than fixed-rate mortgages for the initial few years, which is beneficial, but there is a concern that rates may rise after the adjustment period. On the other hand, fixed-rate mortgages provide stable payments, but during times like now when rates are relatively high, the initial rate itself can be burdensome.

Credit scores also play a significant role. A strong credit score of 760 or above can secure favorable rates, but dropping to around 620 can result in a difference of about 1 percentage point, which can be a concern. Increasing the down payment ratio can improve rate conditions, but this also means a larger initial cash burden must be considered.

In Rockville, properties in areas like King Farm or Twinbrook, which are conveniently located, differ from those in quieter residential neighborhoods. In convenient areas, competition is fierce, making offer conditions more stringent, while quieter areas may offer more room for negotiation.

If you are a Korean household, it is advisable to compare estimates from various lenders, but don't just look at the interest rate numbers; also factor in closing costs. Future rates may gradually decrease, but there is also a possibility that they will remain at current levels for some time, making it difficult to draw a definitive conclusion.
