We replaced the floors, updated the kitchen, replace plastic bathtubs with tile and frameless glass doors in all the bathrooms, and closed the screened porch to add a master bedroom W/M bathroom and closet.Added a dwelling under the new master bedroom kitchen and new deckThe townhouse had an original 1323 sqft with the addition came to a total of 2000 sqft.

When I inspected the apartment it is in a very bad shape - carpets completely destroyed, several big holes on the wall, bathtub is all black, they unplugged the fridge and put food in there, so the whole fridge is molded. 

The bathtub surround is sort of warped so the seal is broken down near the tub.

I have 2 bathtubs in a rental that need to be re-finished. 

Every living unit must have at least one (1) bathroom which includes a flushing toilet, lavatory/sink and a bathtub/shower.

"If you bring me a buyer you represent, I will pay 3.5% for you to do the contract up and represent your buyer".I actually have a single little one page contract for just that (I know a lot of people that would rather climb in a warm bathtub with a blade than sign a listing contract).

When I went for the inspection, and was able to walk through the units, I found that only about 1/2 the heat pumps were working, most of the toilets and bathtubs were leaking causing soft spots in the floors, there was fire damage in a couple of units that had been kinda covered up (wood paneling placed over the studs, but could see the charred studs because there were gaps at the edges), and as far as the new roof,When I brought up these items, they reply was, "well it's a C class property, what did you expect?" 

In our unit we decided to go with a shower instead of a bathtub.

I also imagine injuries are less common in showers than bath tubs.

More than one bathroom makes a live in flip easier - you remodel one bath while still being able to use the other(s).A property with a utility sink makes it much easier to wash dishes than doing them in the bathtub, although your kitchen won't be torn apart forever.A garage to store tools is nice to have.Avoid the "weird" houses.
