Being a 1960s era, it will have everywhere.  6 inch tile floors, hot water pipes, countertops, etc.Would check on that before diving in.

We have an 11-unit apartment building (five 1br/1ba, six 2br/1ba) and want to do a cosmetic rehab (new kitchen, bathroom, paint, sanding, and staining hardwood floors, excluding repairs on MEPs).

The wax ring could be shot, allowing water (and possibly sewage) to leak out around the ring and soak into the floor.

I’m looking for a list of suggested products (cabinets, flooring, tile, etc) to rehab the interior.

In terms of the condition maybe the landlord didn't add AC or went with LVP and carpet over hardwoods in an A location.

A BIG advantage of these is that we didn't have to fully open walls or run ducting to place heating/Cooling units on both floors.

One great thing is that all the carpeting and floors have already been ripped out.

@Ryan Dickerson, while you will ultimately need to either make a somewhat blind leap or hope you can find a contractor that will walk your properties, one piece that I will add is: YOU need to know what type of finishes you are looking at, and understanding their material costs.I.e. are you going to do carpet, LVP, or true hardwoods?  

We added $40K-$50K refinishing the hardwood floors, removing wallpaper, painting walls and updating the kitchen & bathroom with new cabinets, adding granite countertops and creating a BEAUTIFUL dining room off the kitchen that was wasted space as an enclosed porch, and also added french doors leading out to a newly-built pre-finished deck we added so the new owners could enjoy their gorgeous fenced in backyard.

So shortage of inventory prices remain firm or go up.. in the same time this has gone down a few of my floor planes that were 600k 3 years ago I just sold exact same floor plan for 850k closed 7 of them Quarter 3..
