Understanding the Different Types of Mortgages for Illinois Homebuyers

Jeff Salhani May 8, 2026


By Jeff Salhani

The mortgage decision is one of the most consequential financial choices a homebuyer makes, and in the Burr Ridge and western Chicago suburb market it carries considerations that buyers frequently encounter for the first time. The range of loan products available, the way they interact with the luxury price points common to this area, and the financial profiles of buyers that include move-up purchasers, corporate relocations, and investors all affect which mortgage type makes the most sense.

Key Takeaways

  • The conventional loan is the most widely used mortgage in the Burr Ridge market and comes in two forms: conforming loans within standard limits and jumbo loans for prices that exceed those limits
  • FHA and VA loans offer advantages for qualifying buyers but come with property condition standards and loan limits that affect which Burr Ridge and DuPage County properties they can be used to purchase
  • Illinois offers first-time buyer programs through the Illinois Housing Development Authority that qualifying buyers should ask their lender about before the pre-approval process begins
  • Adjustable-rate mortgages offer lower initial rates than fixed products but introduce variability after the initial period

Conventional Loans — Conforming and Jumbo

The conventional loan follows the underwriting guidelines set by Fannie Mae and Freddie Mac and is the most commonly used mortgage in the Burr Ridge and western Chicago suburb market. Conforming conventional loans fall within the loan limits set annually by the Federal Housing Finance Agency, and in Cook County and DuPage County, those limits reflect the elevated home values of the Chicago metro area.

For purchase prices above the limit, buyers move into jumbo territory, which is common in the Burr Ridge estate market where transaction prices regularly exceed the conforming threshold. Jumbo underwriting requires a stronger credit profile, a lower debt-to-income ratio, and typically a longer timeline.

What to Know About Conventional Loans

  • Conforming loan limits in Cook County and DuPage County are higher than the national baseline
  • Jumbo loans are required above the conforming limit with stricter qualification requirements including stronger credit, lower debt-to-income ratios, larger down payments, and longer underwriting timelines
  • Private mortgage insurance is required with less than 20 percent down and is cancelable once equity reaches 20 percent
  • Second home and investment property purchases carry higher down payment requirements and different pricing than primary residence financing

FHA Loans

FHA loans are designed for buyers with more limited down payment capacity or lower credit scores, with a minimum of 3.5 percent down for buyers at 580 or above. In the western Chicago suburb market, FHA loans are most relevant for buyers at price points within the FHA limits for Cook and DuPage County, which remain below most Burr Ridge estate prices, making FHA more relevant for buyers entering the market in Willowbrook, Darien, and surrounding communities.

The FHA appraisal process requires the appraiser to flag safety, habitability, and structural conditions, which can affect older homes with deferred maintenance.

What to Know About FHA Loans

  • FHA loan limits in Cook and DuPage County are higher than the national baseline but below most Burr Ridge luxury price points
  • Minimum 3.5 percent down for buyers with a 580 or higher credit score
  • The FHA appraisal process flags health, safety, and structural conditions
  • FHA loans are for primary residences only and cannot be used for second homes or investment properties

VA Loans

VA loans are available to eligible veterans, active-duty service members, and surviving spouses, offering no down payment, no private mortgage insurance, and rates typically competitive with or better than conventional pricing.

The VA funding fee can be financed into the loan amount. For eligible buyers in the Burr Ridge area, a VA loan is almost always worth evaluating, particularly for buyers targeting properties within the conforming loan limits. VA loan limits align with the conforming limits for Cook and DuPage County, and purchases above those limits require the buyer to cover 25 percent of the excess amount as a down payment.

What to Know About VA Loans

  • No down payment on most VA purchases and no private mortgage insurance
  • A Certificate of Eligibility is required
  • Purchases above the conforming loan limit require the buyer to cover 25 percent of the amount above the limit
  • VA loans are for primary residences only and cannot be used for second home or investment property purchases

Illinois IHDA Programs

The Illinois Housing Development Authority offers mortgage assistance programs for qualifying first-time and some repeat buyers, worth asking about before the pre-approval process begins.

The IHDA Access Forgivable program provides down payment and closing cost assistance forgiven over 10 years for buyers who remain in the home. The IHDA Access Deferred program provides a no-interest deferred loan for the same costs, repayable at sale, refinance, or payoff. Not every lender is an approved IHDA lender, and income, purchase price, and geographic eligibility requirements apply.

What to Know About Illinois IHDA Programs

  • IHDA Access Forgivable provides down payment and closing cost assistance forgiven over 10 years
  • IHDA Access Deferred provides a no-interest deferred loan for down payment and closing cost assistance, repayable at sale, refinance, or payoff
  • Income limits, purchase price limits, and geographic eligibility apply
  • Not every lender is IHDA-approved

FAQs

How do I know whether I need conforming or jumbo financing for a Burr Ridge purchase?

The conforming loan limit for Cook and DuPage County changes annually. If the purchase price minus the down payment exceeds the limit, jumbo financing applies. Jumbo underwriting involves different qualification requirements and longer timelines, so starting the pre-approval process earlier is advisable for buyers targeting Burr Ridge's luxury price ranges.

Does property type affect which mortgage I can use in the western Chicago suburbs?

Yes. Second homes and investment properties cannot be financed with FHA or VA loans and carry different conventional requirements. Condominiums require project approval for FHA and VA financing, and not all condo developments in the western suburbs qualify. Buyers in planned communities should confirm HOA and project approval status with their lender before proceeding.

What is the difference between pre-qualification and pre-approval in this market?

Pre-qualification is an estimate based on self-reported information with no document verification. Pre-approval involves actual underwriting review and produces a written commitment for a specific loan amount. In the Burr Ridge market, a pre-approval from a recognized lender is the minimum standard for a seller to take an offer seriously, particularly at the luxury price points where sellers evaluate financial readiness as carefully as the price itself.
