Same price as our multis, but new instead of a century old and a fraction the sinks, toilets, heating systems etc.  

Are they usually so much a heat loss during harsh winters that owners block them up or what?

Conforming bedroom in a basement -1) Proper ceiling height- varies around the country, usually between 6'-10" to more common 7', and this can get complicated if there are any soffited areas of the bedroom ceiling2) Closet- even a minimum size on this, usually 22" deep3) Proper electrical, proper heating requirements - must have a light and a switch located at the entrance, must be able to be heated4) Minimum square footage size of the room, usually 70 sq feet5) Egress - varies wildly in cost due to conditions, half below ground basement, fully below ground, walk out, set backs etc...Like Bill said - consult the local building dept, the codes for egress window wells are super strict, very detailed and can be confusing, they can get very picky, right down to if it needs a ladder the distance the ladder can stick out from the window well wall and then the clearance in front of the ladder to the window.Be very careful talking to anyone about egress windows with wells, this is one of the most screwed up things we continually hear about, and very expensive to fix if done incorrectly

I feel like most investors might turn down properties because they have oil heat.

I recently bought a short sale house in the Bronx and had it renovated and ready to rent out, until ConEd refused to turn on the heat which had been shut off since last April because the previous owner did not pay the bills.

Landlord pays heat which averages $100/building/month

In case you were wondering the patio is HEATED!

The old Romex is not safe to use with fixtures which generate significant heat (ie. pot lights), so be on the lookout for that.I looked at a house just last week which had been wired with General Electric BradX 12/2 Pb NMD-3 wiring.
