Shopping for a New Canaan home and wondering if your mortgage will be considered jumbo? In this market, many well-located single-family homes and estates sit above standard loan limits, so jumbo financing is common. You want clarity on requirements, timing, and how to present the strongest file. This guide breaks down what lenders look for, how jumbos differ from conforming loans, and the steps you can take now to move smoothly from offer to close. Let’s dive in.
What is a jumbo loan
A jumbo mortgage is any first mortgage that exceeds the conforming loan limit set each year by the FHFA. Because loan limits vary by county, you should confirm the current Fairfield County cap on the FHFA county loan limits page before assuming your loan is jumbo.
In New Canaan and the broader Western Connecticut Planning Region, purchase prices for many single-family homes and estates often exceed national baseline limits. That means jumbo financing is a frequent path for buyers targeting premium properties.
When New Canaan purchases go jumbo
Homes likely to trigger jumbo underwriting include:
- Properties priced well above county or national medians.
- Large estates with acreage, outbuildings, or unique features.
- Homes with extensive renovations that increase the contract price.
Plan for local costs as you budget. In Connecticut, property taxes, HOA dues where applicable, and closing costs such as attorney, title, and recording fees can affect reserves and debt-to-income calculations.
How jumbo underwriting differs
Jumbo loans are usually funded by portfolio lenders or private investors, so underwriting is more selective and can vary by lender. Here is what to expect.
Credit and pricing
- Strong credit scores are rewarded. Mid-700s or higher often receive the best pricing.
- Rate differences versus conforming loans shift with markets. Your rate will be sensitive to credit, documentation depth, and loan-to-value.
Down payment and LTV
- Typical LTVs range from 70 to 90 percent, depending on borrower strength and property type.
- Many lenders prefer 20 percent down for primary residences. Higher LTVs may be possible with stronger compensating factors.
- Standard PMI is not typical on jumbos. Some buyers use an 80/10/10 piggyback to limit the first mortgage size.
DTI and reserves
- Common maximum DTIs fall in the 43 to 50 percent range for well-qualified borrowers. Some portfolio programs allow higher with strong reserves.
- Reserves matter. Expect 6 to 24 months of PITIA, with larger loans, self-employment, or investment properties often requiring more.
Income documentation
- W-2 earners: usually 2 years of W-2s, recent pay stubs, and employer verification.
- Self-employed or partners: typically 2 years of personal and business tax returns, K-1s if applicable, and possibly year-to-date P&L statements.
- Be ready to document large or unusual deposits with a clear paper trail.
Assets and liquidity
- Provide 2 to 3 months of statements for checking, savings, brokerage, and retirement accounts.
- Lenders may apply liquidity discounts to retirement funds and will verify that reserves remain after closing.
Appraisals and property types
- High-value or unique homes may require a luxury-experienced appraiser, a second appraisal, or a desk review.
- Acreage, historic homes, septic systems, and properties with restricted access may face extra scrutiny.
- Confirm insurance and occupancy requirements early, especially for estate properties.
Loan options to consider
- Fixed-rate jumbo: predictable payments, good for long-term holds.
- Adjustable-rate jumbo (ARM): lower initial rate, but plan for future adjustments if you expect to hold beyond the fixed period.
- Portfolio bank jumbo: kept on a lender’s balance sheet and may be more flexible on income or assets, but terms vary widely.
- Bank-statement or non-QM jumbo: can help niche profiles, usually at higher rates and with stronger reserve needs.
Timeline and what to expect
Appraisals for high-value or unique homes can take longer. Build in time for valuation, potential reviews, and any second opinions. A realistic contract-to-close window is often 30 to 45 days, longer for complex properties or income structures.
Your preparation checklist
Gather these documents early to accelerate underwriting:
- Government ID.
- Income: 2 years of W-2s and 2 recent pay stubs, or 2 years of personal and business tax returns with K-1s if applicable.
- Assets: 2 to 3 months of statements for checking, savings, brokerage, and retirement accounts. Include documentation for large deposits.
- Debt: recent statements for auto loans, student loans, credit cards, and any support obligations.
- Property: purchase contract and HOA documents if applicable.
- Explanations: brief notes for employment gaps or unusual deposits.
For reserves, plan for at least 6 to 12 months of PITIA. For larger loan sizes or complex income, 12 to 24 months is prudent. Keep down payment, closing funds, and reserves clearly documented and separated to simplify the paper trail.
Smart rate shopping in Connecticut
- Compare APRs, not just rates. Include discount points, origination, appraisal, and processing fees.
- Ask about lock periods and float-down options. Confirm typical time from lock to close.
- Verify lender and broker licensing in Connecticut using NMLS Consumer Access.
- Review federal disclosures and your Loan Estimate carefully. The CFPB’s Owning a Home guide explains key terms and shopping steps.
If you want a data-driven starting point, the CFPB’s Explore interest rates tool shows how rates shift with credit score, down payment, and loan type.
Appraisal and risk considerations
Luxury and estate properties often need more time for valuation because true comparables can be limited. If the home sits near waterways or in a unique micro-location, confirm insurance requirements early. For flood risk research, use the FEMA Flood Map Service Center and discuss coverage with your insurer.
Local costs to plan for
In Fairfield County, factor these items into your budget and reserve planning:
- Property taxes for the specific address.
- Attorney fees, title insurance, and recording charges at closing.
- HOA dues, if applicable, and any community transfer fees.
- Ongoing maintenance for acreage, historic features, or complex systems.

Strategy for NYC-to-New Canaan moves
If you are relocating from Manhattan or another borough, align your financing timeline with sale, vesting, and liquidity events in the city. Clarify whether you will close before or after selling, and how reserves will be documented. For buyers with significant brokerage assets, speak with your CPA about tax and liquidity considerations before you apply.
