In the area you are making into a bedroom. the window will need to be large enough to allow a fireman with an airpack to enter in.     

Foundation work, new HVAC, windows, siding, roofs, gutters, paint.

You may have a good one or two in your line-up, build a great business with them, and then have to boot them and start the process afresh all within a 12-month window.

Windows are older and do NOT accommodate an AC unit.

@Mike Franco, tell them to go buy a window unit.

When eating at a restaurant like that, we try to get a window seat where we can see our car. 

The windows or the original from 1980 and do not stay open. 

The title search revealed two liens (2018 and 2019) regarding a falling down facade in the front (about 2 feet off the ground below the front window).

@Ricardo NietoWhy not give a very short window for a response from the seller, and if they don’t respond, have an offer ready to make on the next property?
