When figuring costs, here are some things to consider:- Many jurisdictions will require permits to demo a house- If permits are required, a Demo Survey will likely be required (and other surveys/tests)- If the houses are old, you may need an asbestos survey- If there is asbestos, you'll need to pay a remediator to remove- You'll need to pay for labor to demo as well as haul-away and dump feesYou can probably find a company that will do all this turn-key for you for not too much more than what you'd pay to piecemeal it.

I spent 12 hours today including packing the truck, the big Home Depot run and several trips to the corner hardware store replacing the valve and doing the wall demo and rebuild.

(acknowledging you're in ATL and I'm in NE Ohio so things will be different).How much of that demo work did you do yourself?

I had a list that was 4000 names and I wanted to halve it without buying a partial list, so I added his tip to put in home values from 100K to 300K since that's my investors demo anyways and I figured it would narrow down my list and drop the million dollar homes that I won't be touching anyway.

I'm doing my best with the comps but I have no idea how to calculate things like cost of demo, for example.

A couple of years back I was first in line to pick up a completely gutted house (not fire damage - just foreclosed after the demo part of a complete re-architecture) for $100K in a $400K neighborhood.

Incomplete demo: removed cabinets from wall, remove couple soffits, and broke a soffit in bathroom w/o finishing or cleaning up.

Where I am you have to have a permit to do any kind of demo due, even minor, due to air quality control issues.

You can give them a summary of "budgetary estimates": just the high level phases (demo & site prep, foundation, etc).
