I just re-roofed a house in NPR earlier this year:Irv Albright RoofingVery professional, competitive and easy to deal with.

Hi All,I purchased a distressed property where I was able to get a good discount on due to condition.One of the issues in the house is the house has two major roof leaks, that caused the ceilings to collapse in a bedroom and a bathroom.I've had a roofing contractor come in, and he would fix the source of the leaks on the roof.  

I am rehabbing a 3 story rowhome in Philadelphia and had to replace the roof.

I'd look for the big ticket items first.. how's the roof, siding  or do you have to install a new HVAC?    

They look at the appliances, roof, condition of walls, underneath all sinks for leaks, fire extinguisher in order, smoke detectors operational and working, screens on windows, locks on windows and sliders, A/C filter changed.

Quick Analysis For youARV $140k * 70% = $98k (search for 70% rule in the forums, it is a good rule of thumb to cover carrying costs, acquisition costs, and rehab profit)Always assume minimum $10k in repairs unless seller tells you it needs more (roof, siding, etc) = $88kProfit you want to make - ~$5k = $83kYou need to get it for $83k or less as a very rough estimate.Ask the seller what they would take for a cash offer today, if they won't give you a number I would give them a range $75-80k to see if they express any interest before driving out to the house.

HOA $-Cap Ex and Ops $150.00 (this is my minimum per roof.

Second story the brackets are used as stops, otherwise drunk college kids get out on the roof to sun bath.

One of the investors off my list told me if it has solid walls and a good roof I don't care what the inside looks like I want it.

You don't need to replace it all the way up to the roof, because it becomes a gas vent after the last plumbing fixture joins in.
