No restoration/rehab needed, turnkey. 

@Tomie DeRocherHave a storm restoration contractor inspect your roof.

This is good news, my faith in the justice system will be restored when justice is done.

Hello, name's Dan, I'm a fish and wildlife biologist (Montana State University) and I've been self employed for about 10 years running my natural resource restoration business and adding to the real estate side as I have funds.  

Did you refinance out fo the first one, and do a that one time restoration?

I googled it for you.The IRS says this:Replacement of the furnace in your residential rental property:Is generally a restoration to your building property because it's for the replacement of a major component or substantial structural part of the building's HVAC system.

I am looking at a duplex which is in a historical restoration area in my city.I have a contractor who’s done multiple historic renovation in this area.

@Kyle Jensen Another option is to look up the nearest ReStore.
