The building itself is historic, but has had updates to plumbing, electrical and HVAC to suit office space needs.

We spent the last 2 days doing massive plumbing "repairs" to old galvanized supply lines with one shut off for 7 units.

Full rehab meaning, foundation, roofing, plumbing, electric, appliances and cosmetic work?

You've got no plumbing for 8 people.

“The water heater might go out, I know a window is broken, there are tree roots destroying the plumbing and you may not be able to flush a toilet soon, and I know some of the electrical is fussy...but I have no plans to make any of it right.

I'm being told that I need to pay for a check up on HVAC, plumbing, and electrical systems?  

BUT our plumbing guy suggested we add a sewer check valve ($595) & sure enough the new sewers flooded the basements in the street but not ours.We have had a few properties since & I always replace the sewer lines as the ongoing maintenance is brutal & when it blocks & floods the tenants basement you're usually away on vacation. 

Going off the video the stains on the ceiling are in the 1st unit, I doubt it's a roof leak, it could be from the plumbing from the 2nd unit.

. - Partially updated plumbing with need for completion of a copper repipe and PVC.- Stucco done in a sub par fashion - New Roofing placed over old wood shingles - Evaporative cooler leaking onto the roof.- Overall outdated and ugly interiorYes, It’s a lot.

The property in the back, the plumbing comes through my mom's part of the property.
