I furnished my rental almost entirely from rich neighborhood curbs
Beds, dressers, mattresses, ... id scope out a mattress in a neighborhood and ask the owner why.
One lady slept on it for a month. Didnt like the firmness
One dude said his kid got sick on it. Easy clean on basically a new endy mattress.
Bed frames were a sweet score. A couple screws and they were brand new!
Couches , chairs, lights ... all easy scores by taking an indirect route home during spring through the rich streets.
