Based on previous and current pictures only, I can see that they have painted the interior of the place.

There are big holes that are in the roof letting water run right into the house and animals could get in it.mismatch windows all over the place.massive water damage on the interior.

The Tenant/Buyer shall henceforth be responsible for all maintenance and repairs up to $500.00 per occurrence upon said property, both interior and exterior.

I can reasonably estimate the cost of repairs on the exterior, but what about the interior.

I can get comps, check titles, and get a market value, but not sure if there is a good technique on creating an ARV without seeing the interior of the house.

Additionally, evaluate the outstanding maintenance on the property such as roofing, flooring, interior/exterior paint, appliances etc and see what their life expectancy is.  

**Side note....be careful not to spend too much money on an interior designer if you're not in the luxury market.

But to point, they were building modules for a large multi-unit complex located in Clarence NY for a rental/investment company.The build interiors were more 'high-end' given the tenant demographic they were appealing to.Their contact information is: Jamie Kline(716) 270 5526iQmodular homeshttp://www.iqmodular.com

Okay late night update:Numbers still workGot the HVAC cost way downGot the Roofing cost way downgot the potential framing numbers inline found several supply houses to get products interior products at a reduced costFound enough 1" hex tiles at Habitat for Humanity to do one of the bathroom floors for a 85% discount!

There are some that do, but there are also some general contractors who would probably do that kind of interior work.
