We ripped out and completely redid the kitchen, bathrooms and living room.

My plan would be to put about 20k into the kitchen, floors, and bathrooms hoping to turn a 100k profit (numbers don’t work as a rental) and buy a property that is livable but needs work and do the same again over the next couple of years.

Depends on your end user, if you're doing small spaces, short terms, etc they may want a gross lease with a kitchen.

It needs a new roof, new kitchen cabinets, bathrooms finished.

The kitchen, master bath and laundry room have dark ceramic tile with built-in pits and fairly wide, dark grout.

Work has included entire replacement of lower level flooring/sub-flooring, new roof, replacement of half the interior sheetrock, reconstruction of front and back decks, reconstruction of kitchen and bathrooms from ground up.

or is there a "kitchen" number or a "bathroom" number that is generally in a safe zone? 

Two tone frame-less kitchen cabinets.

She moved, because the damage was just to daunting for her to remedy, it took me a good two months to deal with the full renovation kitchen and bathroom, and of course several attempts at refinishing the floors and getting the cat urine and roach feces smell out.Be safe, be healthy, be clean!

I only spent $20,000.00 to rehab the kitchen.
