Remind you I am a contractor for 30 years, we have replaced the dishwasher twice, the refrigerator once, they broke the screen door off claiming wind, broke a toilet tank off the base.

What I hope to do is determine how far off my estimates are from how they actually pan out.

New paint on all surfaces inside and out, new counter tops, light fixtures, ceiling fans, appliances, vanities, toilets, faucets, some new doors, quite a bit.

Fixing the same number of toilets isn't going to be proportionally more expensive, so that kind of expense will be lower as a proportion of the real estate value/gross rent.Am I on the right track here?

That is a LOT better return that I get owning rentals...and there were NO broken toilets or trouble tenants. 

I am a renter myself and our toilet flaps started staying up after flushing, causing the constant run of water.  

I do have a few concerns though, such as the value and how the property will pan out after inspection.

Your profit can go down the toilet with one repair.

You'd then need to allow for a small closet elsewhere in the room, but guests would have an accessible toilet.

If you don't want to scrub toilets and fluff pillows if the cleaner doesn't show up to a short-term rental that you own/manage you're going to have a hard time.
