Two Lincoln Park greystones went on the market a few blocks apart one spring. Similar square footage, similar lots, similar asking prices. One had a basement wine room with a glass wall, custom racking, and climate control that cost about what a nice car does. The other had an overhead sewer and a basement that had been dug down so a six-foot-two buyer could stand up without ducking.
Guess which one drew the offers.
It wasn't the wine room. Buyers walked through it, took a photo, and then asked what every Chicago buyer asks about a lower level: "Has it ever taken on water?" The seller with the overhead sewer had a one-word answer and a receipt. The seller with the wine room had a pause.
If you're not from Chicago, here's the short version. A lot of older homes drain the basement through a floor-level line tied into the city system. A big summer storm hits, the system backs up, and your finished basement becomes a very expensive swimming pool. An overhead sewer conversion raises that plumbing so the backup has nowhere to go. It's ugly work. Nobody puts it in the listing photos. It runs well into five figures, and it's one of the few improvements I've seen buyers at that price point treat as a must-have instead of a bonus.
That's the pattern. The improvements that pay off at resale remove a fear. The ones that quietly don't are somebody else's taste, installed permanently.
Wine rooms, theaters with tiered seating, that very specific tile somebody fell in love with in Milan. Fun to live with. At resale, a buyer sees a line item they didn't ask for and sometimes a demo cost. I'd rather a seller put that money into the roof, the windows, the sewer, the electrical panel. Boring stuff, sure. It's also measurable and easy to defend in an appraisal.
I've spent 20 years running teams and coaching agents, and the hardest conversation is always the same one: telling a seller their favorite room isn't adding value. It's not an insult. The next owner is writing the check, and they pay for what solves their problems.
Developers and investors already get this. If you're renovating a two-flat in Logan Square or a greystone off Armitage, spend on what the inspector writes up first. Then do the fun stuff with whatever's left.
And if you really want the wine room, build it. Just don't expect the next buyer to pay you back for it.
