Now we have found an awesome place in the mountains, but that needs significant work for remodel (new boiler, plumbing, insulation, bathrooms, windows, flooring, drywall...).

We figure $3sf for laminate floors so that multiplied with a quick SF number + tile gives us floors, etc, etc.  

The tile flooring did not match throughout the house, the grout lines were not even, and some areas around the edge of the time had almost 2" of grout instead of cutting a piece of tile for the edge.

I did completely renovate the rest of the units, kitchen, baths, floors, etc so I don't expect to have major expenses aside from the ones I mentioned.  

We are putting in new floors, total paint job inside and out, new kitchen.

They can't handle the paint and floors though.

The seller told us, the house needs EVERYTHING, from roof, kitchen, bathroom, floor, wall, ceiling, lights, lawn, doors, it's pretty much a big rehab.

Ok BP family finally got my first house that I will be house hacking in a few (hopefully) but I'm having a issue with the first floor tenant.

(HVAC and water heater are end of life, plus needs interior/exterior paint, flooring, and other significant but not major issues). 

I'd personally be doing the framing, floors, sheetrock, HVAC, among other things.
