Low Income affordable housing - tend to be rougher on the units, they get a basic 1 tone paint, inexpensive flooring package, no disposal or ice maker or dishwasher - Deep Clean and Safety is my concern.

As an investor you should expect an excellent standard of care and customer service packaged with transparency.

But, it doesn't hurt to start with a meeting with your building inspector - He may have already encountered something similar in town and has worked through the issues and made some decisions on how they will enforce/interpret the code as it relates to existing conditions....

Obviously, you will need to deduct for repair estimates and "safety margins" plus other expenses you will encounter."
