Hello, the tenants of one of my condo property were served with (3) days for not paying rent and they moved out; however, they damaged the walls (holes), doors (cracks), broker shower handle, etc. 

Professionals drill (two feet or the longest masonry bit available) into the hole every 24 inches around the exterior and interior (if the basement is not finished) perimeter of the building and spray the chemical into the hole.After you have sprayed the chemical in the hole patch the hole with cement so the rain doesn't flush the chemical out.

Unless your in a market like the Bay area were you pay 1.5 mil for the lot and build a nice spec for 200 a foot say 3k feet for 600k  and have 2.1 in it and sell for 2.9  which is common the 15% of project cost work.but if your in a market were lot is 100k   build is 200k and end product say is 350k.. and you pay 30k to the builder that is far to much by double.we hire for flat fee if we are financing the whole job and they are simply acting as GC and have no monetary involvement.  10 to 15k a door. is what we pay.. and if we are so inclined there can be a bonus if we do real well.hope that helps.. careful to tag your jobs to % of gross construction costs you may not like were you end up.

The house should have been condemned because of holes in the roof and floors (in several areas).

I'm a first time buyer with some holes in my credentials, I.e.

The building is currently completely vacant and only has a concrete floor, studs and a roof...it's a real s***hole right now and I love it. 

Instead of 'returning' deposit from '15, and having two remaining write new check, can anyone suggest wording/letter that I could have the moving out tenant sign stating something along the lines of 'I, ____, have received my full deposit back, including interest, from my roommates Xname and Zname and do not expect any additional monetary return from my landlord, _____' ? 

Let me try to be more clear, and feel free to poke holes in the thinking.

Another post-tenant property had multiple holes in the walls and the entire tub/shower insert was falling out.  

My worst fears were realized when we found there was a big hole in the roof, and over $10,000 in damage to the property.
