Shopping for a $1M-plus home in Hinsdale and not sure if you’ll need a jumbo loan? You’re not alone. With many properties priced above typical lending caps, understanding how conforming limits work can save you time, stress, and money.
In this guide, you’ll learn how to check DuPage County’s conforming loan limit, when a mortgage becomes “jumbo,” what lenders usually expect, and how to structure your financing to stay competitive on a premium home. Let’s dive in.
Conforming vs. jumbo at a glance
A conforming loan meets size and eligibility standards set by federal agencies so it can be sold to Fannie Mae or Freddie Mac. A loan becomes a jumbo when the loan amount exceeds the county’s conforming limit for the year. The Federal Housing Finance Agency publishes these limits each year and provides a county lookup tool.
As a reference point, the FHFA’s published baseline single-family conforming limit for 2024 was 766,550 dollars. The high-cost area ceiling for a single-family home in 2024 was 1,149,825 dollars. DuPage County, which includes Hinsdale, has historically followed the baseline limit rather than the high-cost ceiling. Always verify the current-year limit before you write an offer.
You can confirm the latest county limit using the FHFA’s conforming loan limits map and lookup tool. The FHFA explains how the limits work and updates the figures annually.

How to check if you need a jumbo in DuPage
Use this quick process for any target price.
Confirm the current-year conforming limit for DuPage County on the FHFA site.
Calculate your projected loan amount: Purchase price minus down payment.
Compare your loan amount to the conforming limit. If the loan is greater than the limit, you will need a jumbo loan.
Example using 2024’s baseline limit: If you buy for 1,000,000 dollars with 20 percent down, your loan is 800,000 dollars. Since 800,000 dollars is above the 2024 baseline of 766,550 dollars, that scenario requires a jumbo loan. If you increased your down payment so that the loan amount were at or below the limit, it could qualify as conforming.
Why jumbo loans differ
Jumbo loans are not eligible for purchase by Fannie Mae or Freddie Mac, so lenders either keep the loan on their books or sell it to private investors. That difference leads to distinct pricing and underwriting.
Rates and pricing
- Jumbo rates and fees vary more by lender and market conditions. At times they are close to conforming rates, and at other times they carry a noticeable premium.
- To gauge market trends, review broad rate surveys like the Freddie Mac Primary Mortgage Market Survey and request live quotes from several lenders on the same day for an apples-to-apples comparison.
Credit score and debt-to-income
- Stronger credit is often expected. Many lenders target mid to high 700s for best pricing on jumbo loans.
- Lower debt-to-income ratios are common for approval and better rates. Keeping your DTI below 40 percent can improve your options.
Down payment and loan-to-value
- A 20 percent down payment is a typical baseline for many jumbo programs.
- Larger down payments, such as 25 to 30 percent, can expand your lender choices and reduce your rate.
Reserves and documentation
- Lenders often require 6 to 12 months of reserves after closing, and sometimes more at higher loan-to-value ratios or for self-employed borrowers.
- Expect full documentation: two years of tax returns, W-2s or 1099s, recent pay stubs, and 60 to 90 days of bank statements. Large deposits usually require explanations.

Appraisals and property details
- Appraisal reviews may be more detailed on jumbo loans. Unique homes, large lots, or extensive renovations can increase review time.
- Condos, co-ops, and mixed-use properties often trigger additional project-level reviews that can affect timing and eligibility.
Mortgage insurance and piggyback options
- Private mortgage insurance is not typically available on jumbo loans the way it is on conforming loans at higher LTVs.
- Some buyers use a piggyback second mortgage to keep the first mortgage at or below the conforming cap. This can help you avoid a jumbo, but it adds complexity and may increase overall borrowing costs.
Product types and lender channels
- Jumbo options come from national lenders, regional banks, credit unions, and private banks. Mortgage brokers can also shop multiple investors for you.
- Some borrowers use portfolio or non-qualified mortgage programs that allow alternative income documentation or asset-based underwriting.
Hinsdale and western DuPage context
Hinsdale is a high-amenity western suburb with many single-family homes that exceed conforming limits. Larger lots, custom builds, historic homes, and recent high-end renovations often push prices into jumbo territory.
Neighboring areas like Clarendon Hills, Westmont, Downers Grove, Burr Ridge, and Oak Brook include both mid-priced neighborhoods and luxury pockets. If you are trading up for more space or a premium location, you will likely evaluate jumbo financing.
Inventory above 1,000,000 dollars is typically tighter than entry-level stock. That can limit comparable sales, which sometimes makes appraisal support and timing more sensitive for jumbo loans. Build a little extra time into your contract if you are buying a unique property.
Get jumbo-ready: a practical checklist
Use this list to prepare before you tour homes.
- Confirm limits: Check the current DuPage County conforming limit on the FHFA site and set a target loan amount.
- Credit: Aim for a 740-plus score for the best pricing. Pull your credit early and address any errors.
- Down payment: Plan for at least 20 percent. If your goal is to keep the first mortgage at or below the conforming cap, model piggyback options with your lender.
- Reserves: Set aside 6 to 12 months of total mortgage payments as post-closing reserves.
- Documentation: Gather two years of tax returns, W-2s or 1099s, recent pay stubs, and 60 to 90 days of bank statements. Prepare letters of explanation for large deposits or transfers.
- DTI: Keep your debt-to-income ratio under 40 percent if possible.
- Pre-approval: Obtain a full underwritten pre-approval from more than one lender, not just a prequalification. Ask about jumbo-specific turn times and appraisal scheduling.
Smart lender shopping and timing
- Compare at least three options: a national mortgage lender, a regional portfolio bank, and a credit union or mortgage broker. Pricing and underwriting flexibility can vary.
- Ask about appraisal timelines, second-appraisal requirements, and how long pre-approvals remain valid.
- Discuss rate lock strategy, including lock periods long enough to cover appraisal and underwriting, and whether float-down options are available if rates improve.
Structuring options near the limit
If your budget is close to the conforming cap, consider these scenarios with your lender.
- Increase down payment to bring the loan amount at or below the conforming limit.
- Use a piggyback second mortgage while keeping the first at or below the cap. Review total interest cost, payment structure, and prepayment options.
- For buyers with substantial liquid assets, explore portfolio or private bank options that consider assets more heavily in underwriting.
Offer strategy for Hinsdale homes
- Build in time: Jumbo appraisals and underwriting can take longer, especially for unique properties. Write timelines that match lender expectations.
- Show strength: Provide a detailed pre-approval letter and proof of funds for down payment and reserves.
- Plan for appraisal: Consider appraisal contingency language and be prepared to address gaps if comparable sales are limited.
Taxes, fees, and closing cost planning
- Larger loan amounts can bring higher origination or underwriting fees. Ask lenders for a detailed loan estimate early.
- Estimate property taxes and insurance carefully, since they affect your debt-to-income ratio and monthly payment.
- Remember reserves. Many jumbo programs will want months of reserves even after you pay closing costs.
Verify with trusted sources
- Check the current conforming loan limit and county mapping on the FHFA conforming loan limits map and lookup.
- Track overall rate trends with the Freddie Mac Primary Mortgage Market Survey.
- Read a plain-English explanation of jumbo loans and documentation from the Consumer Financial Protection Bureau.

FAQs
What is a jumbo loan for Hinsdale buyers?
- A jumbo loan is any mortgage where the loan amount exceeds the FHFA’s conforming limit for DuPage County for that year, which makes it ineligible for purchase by Fannie Mae or Freddie Mac.
How do I know if my Hinsdale purchase needs a jumbo?
- Subtract your down payment from the purchase price; if that loan amount is greater than the current DuPage County conforming limit, you will need a jumbo loan.
What was the 2024 conforming limit and why does it matter?
- The 2024 baseline single-family limit was 766,550 dollars; DuPage has historically followed the baseline, so many 1,000,000 dollar purchases with 20 percent down will exceed the limit and require a jumbo.
Are jumbo rates always higher than conforming?
- Not always; the spread changes with market conditions, which is why it helps to compare live quotes and review broad trends like the Freddie Mac PMMS.
What credit score and reserves help with jumbo approval?
- Many lenders look for credit scores in the mid to high 700s for best pricing and want 6 to 12 months of reserves after closing, with more possible at higher loan-to-value ratios.
Can a piggyback loan help me avoid a jumbo near the limit?
- Yes, a second mortgage can keep your first loan at or below the conforming cap, but it adds complexity and may increase your overall borrowing cost.
