There were two buyers looking at properties in Fairfax. One had a credit score of 760, while the other had a score of 640. Even though they were looking at homes in the same price range, the loan conditions they could receive varied significantly. Failing to understand this difference could put you at a disadvantage right from the moment you make an offer.

According to Zillow, the average home value in Fairfax is $792,718, which is a 2.8% increase from a year ago. Redfin reports that the median sale price across Fairfax County was around $813,000 for the three months leading up to May 2026. The Zillow median for the entire Fairfax County is reported at $696,057, showing some variation in the metrics, which indicates that there are significant differences based on the type of housing and neighborhood.

A buyer with a credit score of 760 would qualify for the best interest rates in conventional loans. If they can make a 20% down payment, they can start without PMI, and even if they can't make that 20%, they can eliminate PMI once they build equity. On the other hand, a buyer with a score of 640 may be approved for a conventional loan but could face higher interest rates, making FHA loans potentially more favorable in terms of actual monthly payments.

FHA loans allow entry with a down payment of 3.5% for those with a credit score of 580 or higher, while those with scores between 500 and 579 need a 10% down payment. However, the mortgage insurance premium will apply throughout the loan term if the down payment is less than 10%, which is a disadvantage compared to the PMI elimination conditions of conventional loans. This means that while some aspects may be favorable, others could be burdensome, so it's essential to evaluate both credit scores and available cash together.

Credit scores do not improve overnight. Keeping credit utilization below 30% and maintaining on-time payments for six months to a year can often lead to noticeable improvements. Instead of rushing to make an offer, taking a few months to improve your credit score before proceeding can lead to better final interest rates. In fact, recent market examples show cases where buyers raised their scores by 40-50 points and received favorable conditions after getting pre-approved again.

Investors looking for rental income should consider that the down payment ratio is typically higher and interest rates are slightly elevated compared to owner-occupied properties. In areas like Fairfax, where demand for school districts is steady, the risk of vacancies is relatively low. However, rather than assuming guaranteed price increases, it's safer to conservatively factor in management costs and vacancy periods to assess cash flow.

Fairfax County is designated as a high-cost area by the FHFA, with the core loan limit rising to $1,249,125 by 2026 (the national standard is $832,750). Most transactions in the median price range are handled through conventional or FHA loans, but if you're targeting single-family homes with large lots or well-remodeled properties, you may need to consider jumbo loan options as well.

Jumbo loans have stricter underwriting criteria than conventional loans. They typically require a credit score of 700 or higher, and down payments usually need to be between 10% and 20%. Income documentation is also scrutinized more closely, so if you're self-employed, organizing your tax documents in advance can help reduce the processing time.

One reason Korean families prefer Fairfax is the school district. While it's good to refer to ratings from GreatSchools or Niche, school district boundaries change frequently, so it's wise to verify the assigned school for any address of interest before signing a contract.

Families moving from out of state should also be aware that property tax rates and insurance structures differ from their previous residences in Virginia. Just as important as the credit score is calculating the total monthly costs that will actually be incurred. For those newly immigrating from Korea and preparing to settle, the short credit history in the U.S. can be a hurdle, but some lenders recognize rental payments or utility bill payment records as alternative credit data, so it's advisable to inquire with multiple institutions.

In summary, if you have a high credit score and cash reserves, a conventional loan seems to be the more advantageous long-term choice. If your credit score is still lacking, starting with an FHA loan and considering refinancing later could also be a viable option.
