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.

@Mark Fries thanks for the info, I will keep that in mind.

Larry Fried , thanks again for your response.I would love to start from a cosmetic rehab, as first step, and see how it goes.What would you suggest as first steps to find the right deal?

I would have expected an OSB/plywood sheathing with plastic house-wrap or felt paper depending on the age. 

Should I be concerned that I might fry this new thermostat if it is setup for 750mv but I have a 24v system?

Holey Moley, my brain is fried today....I think it's time for a day off....I'm glad you chimed in!

While the numbers affixed to the box are permanent I wanted to find if anyone has found a material that adheres to plastic that can be removed after the tenants move out.These tenants put their last name on the outside of the metal box that I replaced that was broken.

@Larry Fried Thank you for your advice and I will be sure to do just that!

@Larry Fried I would love to hear from you which companies you worked with in KS.
