Interest-Only Loans in Fairfax
What is an interest-only loan and how does it work?
An interest-only loan lets you pay only interest for 5-10 years, then the loan converts to principal-and-interest. Your payment jumps at reset. It's designed for buyers who expect income growth or plan to refinance before the reset.

Interest-only loans are less common than conventional or FHA options, so fewer lenders offer them. Retail banks and mortgage brokers carry them, but availability varies by lender and market conditions.
Underwriting is tighter because lenders assess your ability to handle the payment jump when interest-only ends. Most require full documentation of income and reserves. Closing timelines run 17-21 days, similar to conventional loans.
04
Interest-only loans make sense in Fairfax for buyers with strong income who plan to refinance or sell within 5-10 years. If you're staying long-term, the payment reset becomes a real cost — plan carefully.
The conforming limit of $1,249,125 keeps IO loans accessible here. Above that, jumbo rates and terms shift the math. Below that, conventional with PMI often costs less over time than an IO reset.
05
Interest-only loans start with lower payments than conventional 30-year fixed. But when the interest-only period ends, your payment jumps sharply. Conventional loans have one steady payment for 30 years.
If you plan to stay in Fairfax long-term, conventional often wins despite higher initial payments. IO loans work best for buyers who know they'll move or refinance before the reset hits.
