There Are Chicago Homes for Sale With a 3% Mortgage Already Attached. Here's How You Take It Over.

Mortgage rates are sitting around 6.67%. Roughly three out of four VA homeowners are paying under 5%. A huge chunk of people who bought in 2020 and 2021 are sitting on 2.5% to 3.5% loans.

Here's the part almost nobody in Chicagoland knows: some of those low-rate loans can legally be handed to the next buyer. Not refinanced. Not replicated. Transferred, rate and all, to whoever buys the house.

It's called a mortgage assumption, and it's been sitting in the fine print of every FHA and VA loan for decades. In a normal rate market nobody cared. In this one, a 3% loan attached to a two-flat in Portage Park is the real estate equivalent of a lifetime Bears season ticket priced at 1985 rates.

What "assumable" actually means

When you assume a mortgage, you take over the seller's existing loan exactly as it stands: same interest rate, same remaining balance, same payoff date. The seller walks away, you step in, the bank keeps collecting.

Which loans allow it:

• FHA loans — assumable by law, as long as you qualify and the servicer signs off.

• VA loans — assumable, and you do not need to be a veteran. Any creditworthy buyer can take one over.

• USDA loans — assumable, though rare in the Chicago area.

• Conventional loans — almost never. The "due-on-sale" clause in a standard Fannie/Freddie mortgage kills it. This is the big asterisk: most outstanding mortgages are conventional, which is why this is a niche play and not a market-wide strategy.

The math on a real Chicago-sized loan

Say a seller bought a home in 2021 and has about $300,000 left on an FHA loan at 3.0%. You assume it.

	Assume the 3.0% loan	New loan at 6.67%
Loan amount	$300,000	$300,000
Principal & interest per month	about $1,265	about $1,930
Difference	about $665 a month, roughly $8,000 a year, for as long as the loan runs

Closing costs are lighter too. A standard purchase loan comes with an origination fee, appraisal, and the rest. An FHA assumption fee is capped at roughly $1,800, and most servicers charge $500 to $1,500. A VA assumption charges a 0.5% funding fee on the balance ($1,500 on $300,000) instead of the 1.4% to 3.6% a brand-new VA loan would cost.

The catch that kills most of these deals

The loan balance doesn't stretch to cover the purchase price. If the house is worth $420,000 and the loan balance is $300,000, you owe the seller the $120,000 difference at closing. That's the "equity gap," and it's the single biggest reason assumptions fall apart.

Three ways buyers bridge it:

• Cash. Works if you're selling a home and carrying equity into the next one.

• A second mortgage. You assume the first loan at 3%, finance the gap with a second loan at today's rate. The blended rate usually still lands well under a single new mortgage. This is how most successful assumptions actually close.

• Seller financing. The seller carries a note for part of the gap. Uncommon, but it happens with motivated sellers and strong buyers.

The practical filter: assumptions work best when the seller bought recently, put little down, and the home hasn't appreciated much. A 2022 or 2023 FHA purchase with 3.5% down is a far better candidate than a 2018 purchase in a neighborhood that's up 40% since.

Other things to know before you get excited

• It's slow. Servicers take 45 to 120 days to process an assumption. Build at least 90 days into the contract, and expect the seller's agent to push back on a timeline that long.

• You still have to qualify. The servicer underwrites you like a new borrower. FHA typically wants 580 or better (most servicers overlay to 620) and debt-to-income under 50%.

• FHA mortgage insurance comes with it. If the original borrower put less than 10% down, the annual MIP (currently 0.55%) runs for the life of the loan, and you inherit that.

• FHA assumptions are owner-occupant only. Investors can't assume an FHA loan. You have to live there.

• There's no "assumable" filter on the MLS. Not on MRED, not on Zillow, not on Redfin. The loan type only shows up if the listing agent mentions it in the remarks. Sites like Roam and AssumeList aggregate some of them, but coverage is spotty. The most reliable method is still having an agent ask the listing side directly, on every house you're serious about.

If you're the seller: this is a marketing weapon and a liability, both

A home with a 3% assumable loan is more attractive than the identical house next door that needs a 6.67% mortgage. In a competitive situation, that's leverage, and some sellers get a higher price because of it.

Two things to protect yourself:

• Get a formal Release of Liability. Without it, if the buyer defaults three years from now, the servicer can still come looking for you.

• VA sellers, watch your entitlement. If a non-veteran assumes your VA loan, your VA entitlement stays tied to that property until the loan is paid off. That can limit your ability to use a VA loan on your next purchase. The fix is a Substitution of Entitlement, which only works if the buyer is also an eligible veteran.

The honest summary

The case for chasing one: a transferable 2.5% to 3.5% rate is the single biggest affordability lever available to a buyer in 2026, and almost nobody is looking for them.

The case for not obsessing over it: most listings are conventional and can't be assumed, the equity gap makes many of the eligible ones impractical, and the 90-plus-day timeline can cost you a house in a multiple-offer situation.

The right move is to treat it as a question you ask on every property, not a strategy you build your whole search around.

Where I come in

For buyers: I'll ask every listing agent about the loan type before you get attached, run the assumption-versus-new-loan math on the ones that qualify, and connect you with a lender who's actually closed these (many haven't).

For sellers with an FHA or VA loan: I'll verify your balance and rate, market the assumable loan as a headline feature, and make sure the Release of Liability and entitlement questions are handled before you sign anything. My listing commission is 1.25%, with a Zero Commission Clause if you find your own buyer and the freedom to cancel anytime.
