Hello, I have a two-unit SFH (first floor unit & second floor unit which share a main entrance but have separate private entrances once inside the house), located in California (I know...).

Aloha,Poorly maintained tanks, and especially tanks in an environment that creates excessive condensation on the exterior of the tank, often drip onto the floor, damaging floorcoverings and underlying typical subfloors or hardwood flooring.

Another great example is flooring.

Loud neighbors, a poor location, and poor floor plan could mean a constant uphill battle to keep guests happy, and likely a lower ceiling for guest review scores.  

The property in question has commercial space on the ground floor with two, 2 bed/1 bath units above.

@Sol BergrenIs this new flooring or flooring thats been through some usage?

I usually spend my time, if the seller is present, keeping him/her out of the way if needed, pumping tenants for info, taking measurements for room sizes and drawing floor plans with doors and windows and noting appliances and taking pictures.We look for value add properties that are in decent structural and mechanical condition (except for one deal that we got really cheap).

New hvac, floors, paint, new counter tops.

It was quite extensive, all new electrical, hvac, plumbing as well as foundation, painting, floors and yardwork and demo of shed.

I have removed many hives from homes, out-buildings, between floors, etc.
