So I wouldn't buy it unless the numbers meet your criteria even if the location is great. 

Confirmed in several locations.

16 unit apartment building located right on the main street in town. 

You will be limiting your pool of potential buyers.If I were purchasing I'd really take time to figure out if the land and the location was worth it and I'd make sure that I could get a good rent and that I didn't have a lot of competition.I have a client who bought 3 doublewides a few years ago. 

It took me 14 months since my last purchase to locate this opportunity.

They should be able to give you a quote if you give them a detailed description of the location and pole number.

Both appear to be located in the region they are looking for. 

It's a 4 unit in a location that I like.

@Mike McCarthy is right about the feasibility of cutting through a post-tensioned slab, as long as the tendons are located first, but no one wants to incur this expense and the builder can find another buyer.My wife and I have been considering a "light" fix: By cutting access panels into the bedroom wall to the left of the tub, we could move the faucet to the front and replace the narrow strip of tile where the faucet is now.

We did allow painting but were specific about where (NOT in this location) and how much (she totally killed that budget and expected full payment!!!).
