Considering a second home in Chilmark and wondering how the mortgage process differs from your primary residence? You are not alone. Financing a Vineyard retreat often involves higher down payments, stricter reserves, and island-specific factors that can influence your approval and rate. In this guide, you will learn what lenders expect, how conforming and jumbo loans apply on Martha’s Vineyard, and how to structure a strong offer in a competitive, often cash-heavy market. Let’s dive in.
What counts as a second home
Lenders define a second home as a property you intend to occupy for part of the year that is suitable for year-round living. It is not primarily an income-producing rental. This distinction matters because underwriting and pricing differ from both primary residences and investment properties. Most second-home buyers on the Vineyard use conventional conforming or jumbo loans, portfolio loans, or cash.
Government-backed programs like FHA, USDA, and VA are generally aimed at primary residences. For a true vacation home in Chilmark, conventional or jumbo products are the norm. Expect full documentation for income, assets, and credit, similar to a primary residence, with tighter standards.
Conforming vs. jumbo in Chilmark
Whether your loan is conforming or jumbo depends on the Federal Housing Finance Agency’s county loan limit for Dukes County in your purchase year. Any loan above that limit is considered jumbo. Given Chilmark’s high-value properties, many purchases fall into jumbo territory, where lenders apply stricter underwriting and often require larger down payments and more reserves.
Rates on second homes are typically a bit higher than for primary residences. The difference can vary by lender and market conditions. Jumbo loans can carry another pricing premium. Your rate will also reflect loan size, loan-to-value, credit profile, reserves, and whether you pay points.
What lenders look for
Credit and history
- Many lenders prefer FICO scores of 700 or higher for second-home conventional loans, with some allowing 680 on a case-by-case basis.
- Jumbo lenders often look for 720 or higher depending on loan size and profile.
- A track record of on-time housing and installment payments is important.
Down payment and LTV
- Conforming second-home loans may allow loan-to-value ratios up to 80 to 90 percent, but expect stronger pricing with at least 10 to 20 percent down.
- Jumbo financing typically caps at 70 to 80 percent LTV. A 20 to 30 percent down payment is common for high-value properties.
- Lender overlays can push down payment requirements higher for remote or seasonal markets like the Vineyard.
Reserves
- Plan for 6 to 12 months of principal, interest, taxes, and insurance in post-closing reserves for a second home.
- Jumbo loans and multi-property borrowers may face reserve requirements at 12 months or more.
- Some lenders count reserves across all mortgages you hold, not just the new one.
Debt-to-income and documentation
- Conforming guidelines may allow DTIs up to the mid 40s or near 50 percent with compensating factors, but many lenders prefer below 43 percent.
- Jumbo programs often target DTIs under 36 to 43 percent.
- Self-employed or seasonal income buyers should expect full documentation, typically two years of tax returns. Alternative documentation exists but is less common and usually pricier.
Occupancy and use
- Lenders expect personal use. If you plan to rent the home regularly, the loan may be treated as an investment product with stricter terms and higher rates.
- Some lenders tolerate limited occasional rentals, but policies vary and must be disclosed upfront.
Island factors that affect approval
Appraisal and valuation
Chilmark appraisals can be complex. Unique waterfront settings, limited comps, and seasonal swings can create valuation uncertainty. Lenders may request additional comparable sales. Build appraisal contingencies thoughtfully, and be ready to discuss valuation strategy with your lender and attorney.
Insurance costs
Properties in coastal or flood-prone areas may require flood insurance, and many owners add wind or hurricane coverage. Premiums on Martha’s Vineyard can be higher than inland markets, which increases your monthly payment and can affect qualifying. Obtain realistic quotes early so your lender uses accurate figures in the PITI calculation.
Property taxes and fees
Town-by-town property taxes on the Vineyard feed directly into your monthly payment. Get current tax data from the assessor or your agent so your estimates are precise. If you plan improvements, factor in permitting timelines and any related costs.
Seasonal vacancy and rentals
If you intend to rent the home seasonally, disclose it at the beginning. Regular rental intent can shift your loan to an investment classification with higher down payment requirements and pricing adjustments. Undisclosed rental activity may create loan or insurance issues later.
Illustrative Chilmark scenarios
These examples are illustrative and assume you have confirmed the current Dukes County conforming loan limit. Taxes and insurance are modeled separately and will vary by property.
Example A: Lower luxury entry
- Purchase price: 1,200,000 dollars (illustrative)
- If the county conforming limit sits below this level, it becomes a jumbo loan. If at or above, a conforming option may exist.
- Potential structures:
- Around 80 percent LTV conventional: loan about 960,000 dollars, down about 240,000 dollars. Reserves often 6 to 12 months.
- Up to 90 percent LTV may be available on some conforming second-home products, with higher pricing and stricter credit and reserve requirements.
Example B: Mid-luxury tier
- Purchase price: 2,500,000 dollars (likely jumbo)
- Common expectations:
- 70 to 80 percent LTV. Down payment between about 500,000 and 750,000 dollars.
- Reserves often around 12 months of PITI.
- Strong credit and conservative DTI preferred. Portfolio options may allow higher LTV with custom terms and pricing.
Example C: High-end waterfront or estate
- Purchase price: 5,000,000 dollars (jumbo)
- Typical approach:
- Many lenders require 25 to 30 percent down. That is 1,250,000 to 1,500,000 dollars.
- Expect thorough documentation of liquid assets for down payment and reserves, along with evidence of ongoing liquidity.
- Portfolio or private bank lending can offer interest-only or bespoke terms, depending on your overall relationship and assets.
Rate strategy: locks and points
- Lock timing: Inventory is limited and timelines can shift on island transactions. Locking too early can be costly if rates fall. Locking too late risks higher rates. Coordinate your lock with key milestones like appraisal scheduling and loan approval.
- Paying points: If you plan to hold the mortgage for a long time and use the home regularly, consider buying down the rate. Calculate the breakeven based on the lender’s point pricing and your expected horizon.
- Market moves: Rate spreads between second-home and primary loans change with market liquidity, credit profile, LTV, and loan size. Shop multiple lenders.
Winning in a cash-leaning market
- Arrive with a written pre-approval that specifies second-home terms, maximum LTV, reserves, and an estimated rate. A pre-qualification is not enough.
- Highlight financial strength in your offer by clarifying down payment, reserves, and any cash buffer for appraisal variance.
- Prepare for island timelines. Appraisals can take longer. Build a realistic close and inspection schedule to keep your offer credible.
- Use clean contingencies. If you need them, state them clearly. If you have flexibility, signal it without taking on undue risk.
Your step-by-step plan
- Confirm your second-home intent and occupancy plan so the lender classifies the loan correctly.
- Check the current Dukes County conforming loan limit and decide whether your target price will require jumbo financing.
- Review your credit, income documentation, and liquid assets. Aim for strong credit, a clear paper trail, and adequate post-closing reserves.
- Price insurance early. Obtain homeowners, wind, and flood quotes if applicable. Use real numbers for PITI modeling.
- Compare multiple lenders. Ask about LTV maximums for second homes, reserve rules across your property portfolio, DTI limits, and pricing differences for jumbo.
- Secure a written pre-approval that lists product type, max LTV, reserve requirement, and any conditions.
- Align your rate lock with contract timing, appraisal scheduling, and your risk tolerance. Evaluate points with a breakeven analysis.
- Structure your offer to compete with cash. Consider a larger earnest deposit, flexible timing, and clear communication on financing milestones.
If you plan any rentals, talk early
Regular rental use can reclassify your purchase as an investment property, which means stricter underwriting and higher rates. Even if you expect only limited occasional rentals, disclose this to your lender at the start. Accurate classification helps you avoid surprises, protects your insurance coverage, and keeps your closing on track.
