STR cleaners generally set rates that average out, meaning the big stays that mess up the whole house are offset by the one offs that use one room and the bathroom and never touch the stove or refrigerator.

I put in some new flooring and paint, minor electrical, and a couple of ceiling fans (approx 20k in repairs, appliances, travel, and holding)I put in a new refrigerator, washer and dryer, and leased it myself to a family a few months later (6 months lease) through an insurance company because of their home being a total loss.

1  The refrigerator or the smell? 

It will scratch if you push a refrigerator across it (ask me how I know this), but the scratch is not deep or very obvious.

Usually refrigerated food will stay for a very long time - months, in fact - without becoming putrid, though you probably wouldn't want to eat anything out of it.

For example, if the tenant reports their refrigerator isn't working, the system automatically responds with some troubleshooting tips.

The price difference seems to be the same when it comes to dishwashers and microwaves, but much greater when it comes to refrigerators.  

Ft ranch home with new appliances ( Refrigerator, dishwasher, stove(electric or gas), washer/dryer, microwave etc and contemplating whether it requires and electrical upgrade from 100 amps to 150/200 amps.Currently the HVAC system installed for central heating/cooling is  15 amps)and there is gas water heater.Do you anyone know if this needs to a mandatory upgrade or any recommendations around the same and what it can cost to upgrade electric panel to 150 amps/200 amps?

Owing to the trend towards smaller,  more efficient appliances and LED lighting  electrical loads I think are somewhat less than they may have been per SF like in the 70's through 2000's when everybody had incandescent lighting and big tube TVs and refrigerators, dishwashers,  etc. that used 2 or 3x as much power as modern ones.I've had a couple turn-of-century units rewired to remove K&T and failed 'BX" (flexible steel sheathed  2 wire cable)  and agree with other posters the pricing isn't that bad as long as you can find an electrician that has some experience with that kind of work,   and sometimes it might be helpful to open up some cable routes ahead of time for them to use so they don't have to do the exploratory work.
