Last fall, there was a townhouse listing in Centerville that received offers from two buyers at the same time. The contract terms were nearly identical, but one had a credit score of 780, while the other had a score of 640. As a result, the buyer with the 780 score was approved for a conventional loan with only a 5 percent down payment, while the buyer with the 640 score had to switch to an FHA loan, accepting relatively unfavorable terms for both the down payment and interest rate. A single credit score can determine the monthly payment amount.

Looking at home prices in Centerville, the average home value according to Zillow is $631,224, which is a 2.4 percent increase from a year ago. According to Redfin, the median sale price over the past month was $635,000, reflecting an 18.1 percent increase compared to the previous year. The difference in these figures is due to variations in data collection methods and sample timing, but either way, the mid-$600,000 range seems to be the current baseline for Centerville.

In this price range, the required down payment varies significantly depending on the type of loan. For FHA loans, a credit score of 580 or higher requires a 3.5 percent down payment, while scores between 500 and 579 require 10 percent. Conventional loans can start at 3 percent for first-time homebuyers or those with an area median income of 80 percent or less, but generally, the common down payment is around 5 percent. If the down payment is less than 20 percent, PMI, or private mortgage insurance, is added to the monthly payment, and if it is 20 percent or more, this cost is waived. This is why the credit score is a key factor in determining the type of loan.

The interest rate environment also needs to be considered. As of July 2026, the average interest rate for a 30-year fixed mortgage is around 6.6 percent, fluctuating between 6.55 and 6.72 percent according to Freddie Mac's PMMS. Those with lower credit scores often receive higher rates than this average.

Centerville is part of Fairfax County, where the property tax rate for the 2026 fiscal year is $1.1225 per $100 of assessed value, or 1.1225 percent. This is relatively high compared to Virginia's overall average effective tax rate of 0.74 percent. Families moving from out of state often calculate monthly payments based solely on home prices, only to find that property taxes are a larger burden than expected.

First-time homebuyers should also consider Virginia Housing's assistance programs. The HOMEownership down payment and closing cost assistance program offers support of 10 to 15 percent of the purchase price as a forgivable loan, along with $2,500 for closing costs. If you have a credit score of 680 or higher, there is also the Virginia Housing Plus Second Mortgage option, which can reduce the down payment burden to between 3 and 5 percent.

Centerville has many neighborhoods within the Westfield High School district, making it a popular area for Korean families. However, school district boundaries can change frequently based on decisions by the county school board, so it is advisable to verify the assigned school for a specific address before finalizing any contracts, even if you refer to ratings from GreatSchools or Niche.

In addition to credit scores, the debt-to-income ratio (DTI) is also considered for loan approval. Monthly payments for credit card installments, auto loans, and student loans are included in this calculation, so organizing existing debts a few months before making an offer can improve both credit scores and DTI simultaneously.

If you are approaching this as an investment for rental income, keep in mind that the difference in interest rates based on credit scores will also affect your yield calculations. However, the rental market can fluctuate, making it difficult to predict profits definitively.

Ultimately, credit scores are the starting point that influences not only approval but also the type of loan, interest rates, and overall monthly payments. Before making an offer, it may be beneficial to check your credit report and take a few months to improve your score if necessary. Tax rates and assistance program conditions can vary by county and individual circumstances, so it is advisable to consult with a loan officer and a real estate professional before finalizing any contracts.
