That West Loop Two-Flat Math Problem

Shaun Kravat · June 1, 2026

A client sent me a listing on Aberdeen Street last month. Two-flat, solid brick, asking $715K. His first question: "Can I live in one unit and rent the other to cover most of my mortgage?" The answer was yes. But the real story was more interesting than that.

I ran the numbers. With 20% down on a conventional loan at current rates (hovering around 7%), his monthly PITI landed near $4,200. The garden unit was already rented at $1,650. So his effective housing cost drops to about $2,550 a month. That's cheaper than a lot of one-bedroom rentals in the West Loop right now.

This is the house-hack, and I think it's one of the most underrated strategies for first-time buyers in Chicago. You're building equity, getting rental income, and your tenant is essentially subsidizing your down payment recovery. Most people assume they need to start with a condo. I disagree. If you can qualify for a two-flat, the math almost always works better over a five-year hold.

Here's the part that gets overlooked though. West Loop two-flats are getting harder to find. A lot of the original housing stock along streets like Aberdeen, Carpenter, and May has been torn down for new construction or converted into single-family homes. According to what I pulled from the MLS last quarter, inventory of two-to-four flats in the West Loop was down roughly 30% compared to the same period two years ago. Fewer units, same demand. That compresses your buying window.

For sellers sitting on a two-flat in this pocket, that scarcity is real leverage. You're not competing with new-build condos. You're offering something the market can't easily replace. Priced right, these properties move fast, especially when investors and owner-occupants are both bidding.

One thing I tell every investor client: don't just look at the rent roll today. Look at the zoning. A two-flat on an RT-4 lot in the West Loop has optionality that a condo never will. You could hold, you could convert, you could (down the road) explore adding units. That flexibility has value even if you never use it.

If you've been scrolling Zillow looking at $400K condos, pull up the two-flat filter instead. You might be surprised what pencils out.
