He said that I could get about $30,000 of the rehab costs through a program like ygreen.com, basically if you upgrade Windows, roof, drought tolerant landscaping, and other energy efficient items, you are able to get a loan that is attached to the property taxes for the property.

Following the Great Recession, the Big Banks (with $) convinced Congress that it was all the fault of the Local Lenders who live in the communities we lend in & can throw rocks from our back yards to hit the roofs of houses that we've financed. 

Values ranged from $110K to $125K.My had more SQFT than the $110K comp, I had a complete renovation, including a brand new Carrier HVAC with gas furnace, roof, etc.

Been sitting on the market for a while.So the house has been sitting on the market for 75 days in a hot market, no one is in a rush to get paid, foundation issues, roof imploding, smells like cat urine (the smellier the better), so beat up that all the local flippers are scared of it and/or make insultingly lowball offers that the seller has just been round-binning, but hey it's got a great location.

What about when the roof leaks in a big storm?

Over here, you keep the same roof for decades.

The roof was apparently three months old, but looked very poorly constructed.  

My broker informed me that the roof will likely need replaced.

Structure that is not protected from damage (like a roof), will also have an average life expectancy.Survey what you have and replace all the systems due to fail in the next 5 years.  

The house should have been condemned because of holes in the roof and floors (in several areas).
