I've rehabbed the exterior and have started on the interior.

Definitely a fixer upper, like $25/foot for interior, exterior, landscaping, asphalt improvement.

@Alex Craig @Curt Davis - Regarding the issue of how much renovating they're doing, it looks like they're doing a bunch of work on the kitchen/bathroom as well as some exterior work.  

The exterior needs minimal work.  

I definitely recommended it.Looking at what you have listed I would:1) paint inside and outside first ( also any yard or exterior work)2,3) Master bath 3,2) Granite and backsplash - granite may need some lead time4) floors last - definitely leave carpets to the very end.my 2cgood luck

I was thinking replace the interior doors with exterior grade door with weatherstripping and then carpeting the stairs.

Of course in that case the roof was gone and so was the floor between 2nd and 3rd story...exterior walls were generally sound.There doesn't seem to be nearly as much room on the valuation in this case...What is the value of the land, and what would cost of demo be?  

I am about to insulate the exterior of my house and was advised to try ultra flect and I'm looking for reviews.

The deferred maintenance arent major items but they need to be taken care of....landscaping, replace some sod, paint the exterior, minor drywall repairs, replace a shower door...overall the house is solid.

If it's deeper and modifying exterior perimeter conditions won't help, then it's on to dealing with the problem from the interior.
