Shopping for a home in McLean and unsure whether you’ll need a jumbo or a conforming loan? You’re not alone. With prices ranging widely across Fairfax County, the right financing path can save you time, money, and stress. In this guide, you’ll learn what each loan type means, how local price points interact with loan limits, and practical steps to choose confidently. Let’s dive in.
Jumbo vs. conforming: what they mean
A conforming loan is a conventional mortgage that meets Fannie Mae and Freddie Mac guidelines, including maximum loan-size limits set each year. Because these loans are eligible for sale to the agencies, they benefit from standardization and strong market liquidity.
A jumbo loan is any mortgage with a balance above the conforming loan limit for your county. Jumbo loans are not eligible for agency purchase, so lenders use their own guidelines. That often means tighter credit standards, more documentation, and different pricing.
Government-backed options also exist. FHA loans allow lower down payments and credit scores but may have limits below many McLean price points. VA loans are especially important locally. Since 2020, eligible veterans with full entitlement can secure VA financing above local conforming limits (subject to lender requirements), often with no down payment and no monthly mortgage insurance.
Why this matters in McLean and Fairfax
McLean includes many higher-priced single-family homes, while Fairfax County overall has a wider range of price points. That means some condos and townhomes may fit comfortably within conforming limits, but many detached homes in McLean may require jumbo financing unless you adjust your down payment or use an alternative like VA (if eligible).
Understanding where your target homes sit relative to the conforming loan limit helps you decide early whether to plan for conforming or jumbo terms.
Loan limits: how to check and apply them
The Federal Housing Finance Agency (FHFA) sets a baseline conforming loan limit and publishes county-specific limits annually. High-cost areas may have higher limits. FHA, VA, and USDA have their own rules, and VA’s county caps do not apply for buyers with full VA entitlement.
Here’s how to apply the limit to your search:
- Find the current conforming loan limit for Fairfax County on the FHFA website.
- Estimate your loan amount: purchase price minus down payment.
- If your estimated loan amount is above the county limit, your loan would be considered jumbo unless you use a qualifying alternative like VA.
Tip: Limits change yearly, and lenders may have overlays. Confirm the exact figure and your lender’s rules during preapproval.
Practical differences you’ll notice
Credit score
- Conforming loans may accept lower scores, with better pricing as scores rise.
- Jumbo loans usually expect higher scores, often in the 700 to 740 range for best pricing.
Debt-to-income (DTI)
- Conforming programs may allow DTIs around the mid-40s to 50 percent with strong compensating factors.
- Jumbo programs often cap DTI lower and look more closely at overall profile strength.
Reserves
- Conforming loans might require a few months of reserves (your monthly housing payment times several months).
- Jumbo loans often require larger reserves, commonly 6 to 12 months and sometimes more as balances increase.
Down payment and PMI
- Conforming loans can go as low as 3 to 5 percent down, though private mortgage insurance (PMI) applies above 80 percent loan-to-value.
- Jumbo loans frequently prefer 20 percent down. Some lenders offer lower down options with stricter requirements or pricing.
Documentation
- Expect jumbos to ask for more records: tax returns, detailed asset statements, sourcing of large deposits, and explanations of transfers.
- Gifts and nontraditional income get more scrutiny in jumbo underwriting.
Appraisal and valuation
- High-priced homes in McLean may have fewer comparable sales. Lenders may require additional appraisal support, second appraisals, or extra review steps.
Pricing and costs to compare
- Rates: Historically, jumbo rates have been slightly higher than conforming, though market conditions can flip that relationship. Rate gaps change with the market, so always compare live quotes.
- Fees and points: Jumbo loans may carry higher origination costs or pricing adjustments. Conforming pricing tends to be more standardized.
- Overall cost: Compare APRs, not just rates. Factor in PMI (if applicable), required reserves, points, and total cash to close.
- Product range: Jumbo fixed and ARM options exist, but selection varies by lender. Ask about rate-and-term refinance options and any cash-out rules if future flexibility matters to you.
Your options in McLean
- Increase your down payment. If your loan amount drops to or below the conforming limit, you may switch from jumbo to conforming and potentially reduce costs.
- Choose a jumbo loan. If your target home price exceeds conforming limits, a jumbo can finance the full need with one mortgage.
- Use VA if eligible. For qualified veterans and service members with full entitlement, VA can support loan amounts above the local conforming limit with no monthly PMI. Lender overlays still apply, so choose a VA-experienced lender.
- Consider a piggyback structure. Some buyers use a first mortgage at or below conforming limits plus a second mortgage or HELOC. Weigh total costs and flexibility against a single jumbo.
- Shop lenders strategically. In Northern Virginia, national banks, local credit unions, and mortgage brokers each approach jumbo pricing differently. Obtain at least two to three quotes and ask for detailed Loan Estimates for an apples-to-apples comparison.
Simple scenarios to illustrate
- Staying conforming with more cash: If your calculated loan amount is slightly above the county limit, adding to your down payment to reduce the loan to the limit can unlock conforming pricing and possibly reduce mortgage insurance costs.
- Going jumbo for speed and simplicity: If you would need a large second mortgage to avoid a jumbo, a single jumbo loan might offer a cleaner structure with one payment and straightforward underwriting.
- VA route for eligible buyers: If you qualify and have full entitlement, VA can be a strong path in higher-priced segments, often with no down payment and no monthly PMI. Confirm lender experience with high-balance VA loans.
Timeline and appraisal expectations
Jumbo files often involve more review and sometimes longer appraisal turn times. Build extra time into your contract period if you expect a jumbo, are buying a unique property with limited comparable sales, or are using complex income or assets. Ordering the appraisal quickly and responding fast to documentation requests helps keep closing on track.
Quick decision checklist
- Verify the current Fairfax County conforming loan limit.
- Estimate your price, down payment, and resulting loan amount.
- If above the limit, compare jumbo quotes against alternatives like VA or piggyback structures.
- Gather documents early: two years of tax returns and W-2s, recent pay stubs, bank and investment statements, and explanation letters for large deposits.
- Ask lenders to compare total cost: rate, APR, points, PMI, reserves, and cash to close.
- Allow extra time for appraisal and underwriting, especially for high-value or unique properties.
