I know it's kind of hard to tell based on just a few photos taken, but just a ballpark would work.

Basically this is a 2000 sqft raised ranch in a pricier part of the northeast. Holes were punched in the walls, the vanity in the bathroom ripped out, the cabinets/sink were taken from the kitchen, carpet ripped out, sliding door to the deck was removed and glass shattered, graffiti on the 1st floor, etc. etc. The outside of the house is nice... the back yard (which is quite small) needs a little landscaping though)

My realtor who's listing this says it'll probably go for 250K (was sold in '06) for 560K so this is a 'good deal'. Just wondering what a rehab will cost roughly, worst case scenario).
