What are the prices of a yard with a house over there?
By us you can get a very decent place for around 76k USD.. You can even get a nice place for 56k usd but then the house will have a little work, might need a repainting. A broken windows or two.. Overgrown yard but that's nothing of big concern though.
And I think the yards here are much bigger than the average size that such
It varies from state to state here, and also varies quite a bit in New York where I'm at depending on what part of the state you're looking at.
NYC the prices are astronomical for both renting and purchasing real estate as far as I've heard.
The more rural areas of New York you can find nice 3-6 bedroom Colonials and Victorian's ranging 50-300k, depending on the size and condition of the homes and how many acres of land comes with the home.
There's places around here too where you can find houses and trailers for 5-10k and usually are fixer uppers like you mentioned, but we're talking like pure dilapidation out of code and you're pretty much just paying for the land.
