I am mainly concerned about building my skills at assessing the cost of rehabs.  

Taxes and cleaning are direct pass thru expenses to your guests.Have a plan for when something doesn't work (furnace, guests can't get into property, water in basement, etc).Keep us posted, it would be great for you to start a blog or diary here on BP for us to follow your progress!  

@Daniel Sisto  that is my assessment and also the foreign buyer has gotten a very very expensive education at the hands of some pretty tough  marketing companies and not so ethical resellers.

Making progress on the back, getting the big exterior stuff out of the way first.

Do you wait until the end of the lease and assess all damage and repair and charge accordingly?

Hi @Leigh Ann Smith - In short, I agree with your assessment.

Building 24 new construction homes, currently have 14 retail rehabs in progress.

You should start devouring it with both hands until you get the gist and learn to quickly assess a property, its repair costs and After Repair Value (AVR) in the market that you work. 

So there is a disparity between capital outlay and building progress.  

I feel like if I know some of this info I may assess deals differently.
