I'm in Kensington with two roommates in an old house. It's definitely a great deal but if you are willing to live with roommates in a somewhat uncool area, similar deals are definitely possible: https://streeteasy.com/for-rent/nyc/price:3000-4000%7Carea:3...

For instance, here's $3500 for a 4 bedroom/1.5 bath that's on a quiet street but near a lout one https://streeteasy.com/building/171-east-8-street-brooklyn/3...

I was curious too, and it seems feasible. Assuming at least 2 other roommates, you can find a 3 bed for less than 3600/mo. Here's a small 4 bd/1.5 ba for 3350/mo, so about 1120/mo.

Obviously not the most ideal circumstances, but it can be done.

actually i used to live in flatbush the first year i moved to nyc in a "coliving" space, and the rent was very low around 1.2K p/m, but never again going back to that area... Parkside ave station was disgusting honestly.
