Chicago · 2 to 4 unit buildings
Yes. And the best reason is one most articles skip.
Walk down a side street in Avondale, Bridgeport, or Portage Park and you will see block after block of brick two flats. A two flat is Chicago's name for what most of America calls a duplex, two apartments stacked in one building with one owner. Most of them went up in the early 1900s, when land, labor, and materials were cheap. The typical one is more than 100 years old.
Here is why that matters to you. Nobody builds these anymore. Price out the same solid brick building new today and the land, materials, and labor would cost far more than the building sells for. There is a name for that, the replacement cost gap. It just means the building sells for less than it would cost to build again. When you buy a Chicago two flat, that gap comes with it. Nobody can build your competition.
The renters are here too. About a third of Chicago's rental homes sit in small buildings of two to four units, so renters already look for these apartments. The Chicago area is home to 30 Fortune 500 headquarters, second most in the country, plus hospitals, universities, and two airports full of jobs that do not move. People come here after college and tend to stay.
One more thing in your favor. The supply of these small buildings shrinks a little every year as some get converted or torn down, and almost nobody adds new ones. You would own something the city is slowly running out of.
Two things to know going in. Illinois property taxes are among the highest in the country, and Cook County resets home values every three years. Chicago's last reset was 2024, so the next one lands in 2027. The way through is simple. Run your numbers with the real tax bill, not the seller's old one, and remember you can appeal an assessment you think is too high. Second, a 100 year old building will need work at some point. A good inspection tells you what and roughly when, so you can price the work into your offer instead of finding it later. Buyers who plan for both do fine here.
You may need less cash than you think. If you live in one unit and rent out the rest, you can buy with 5% down on a conventional loan, up to four units. On a $600,000 building, that is $30,000 down. FHA can go to 3.5% down on a duplex, with some extra rules. Buying purely as an investment, without living there, usually takes 25% down.
Living in one unit does something else for you. Every month, your tenant's rent helps cover the mortgage, and part of that payment shrinks your loan balance. It works like the 401K match of real estate. It is money added to your side of the ledger just for showing up.
Buy a block, not a city. Do not shop for "Chicago." The city's official map has 77 neighborhoods, and on one street you can find a building at $350,000 and another at $850,000. Picking the right block is the real work, and it is also the opportunity, because a market this big has blocks where the numbers work at almost any budget. When a building catches your eye, run it through our deal analyzer. Put in the numbers and you get a quick read on what the building could look like as a rental, so you can tell in minutes whether it deserves a closer look.
About one in five of our clients buys from outside Chicago, some of them without visiting first, usually after running the numbers on their own city.
If Chicago is on your list, reach out. You don't need to know exactly what you want yet, most people who reach out don't. We will point you toward the neighborhoods that fit your budget and show you how to run the numbers yourself, so the next good building you see, you will recognize it.
