Flooring, Drywall, refinish basement, roof, gutters, tuck point around house, and one full bathroom gut all had to be completed. 

They are built with lots of room for parking, many bedrooms and bathrooms.

If the building is currently recognized as a single family residence,  then you are changing use and presumably will need to sprinkler the building and satisfy other fire rating and STC rating requirements not to mention the added costs of having to run mechanicals for multiple units, multiple kitchens, additional bathrooms etc.  

(Not in bathrooms).Good luck. 

The homes in this area are 3 bedroom and 1 bathroom with full unfinished basements. 

Quote from @Marc Shin: For my STR, should I be using waterproof LVP or regular tiles for the bathroom floors?   

We happened to already have an RV hookup with power/water/sewer, plus a small bathroom building nearby that's about 10x10 split in half, one side with a toilet/sink/shower and the other with a washing machine. 

Strategic $12,000 renovations included minor updates to the kitchen and bathrooms, enhancing the property’s appeal to potential buyers.

How many bathrooms, bedrooms, and garages are in demand?

Or if you got real cajonas, a 3/1 and add a bathroom then rent by room.
