Rent Comps Vary Drastically in Milwaukee--How to analyze?

[Greg Earnest]

Hi BP Community!

I am new to BP and have been lurking on the forums for a while. I am a recent transplant to Milwaukee (from LA) and looking to put in my first FHA offer in a 2-4 unit in about 2 months so that I can househack.

Something I’ve noticed in the city is that rent can change drastically from block to block-even with similar unit finishes and parking, which makes it hard to be confident in my underwritten rents. Zillow and rentometer seem useful, but not quite specific enough on a block by block basis.

How do people account for this in their analysis?
