In my area a good rule of thumb is that a basic installation for a basic replacement window (same size as old window) is about the cost of the window.

You might see a perfect spot for a new driveway but until you ask the neighbor that has been in the neighborhood for 55 years tell you the size of the tree that stood where you are looking you didn't know the trouble you about to walk into.I guess at the end of the day it is your approach.

If provided with documentation to being service animals does that waive my restrictions on breeds, numbers, size etc.?

As a rehabber, you know what angle to drive a nail into a door jam and what size nail to use depending on the framing or screws, I doubt you read that in a book and then went out and hung a door properly.

If it's really old you could have a galvanized water main going to the street as well as a host of other issues.I think 15,000 a door is about right for the size of the units and fixing the outside as well given that there are no more other large surprises that could run the total cost up.Take 42 units at 15k a unit rehab = 630,000If landlord is to pay water you use 60% for total operating costs averaged over time.

Asad - $8,000 sounds a bit low for kitchen especially in that price range.. but I suppose if it just needs some repairs then that is possible.On a deal this size it is ok to go against the 70% rule a bit, in my opinion.

I'd come in with a 50 size excavator and start pulling that dirt back.

I found one that was a 3" duct, but if it's exactly the same size as the duct it won't go in.

Invitation size mailing, yellow letter, big postcard, etc.

I too, try to follow this strategy... just need a brain the size of Amit's !!!
