The land value  and demo costs might   decide it. 

If you hire a licensed general contractor to do the demo, they are the one liable for the lack of asbestos testing.

Demo is coming along.  

All excluding land costs and in Denver.I finished a 7 unit town home project in August 15, near Sloan's Lake - we finished at $165 per ft - this is demo to door bell with all costs includedI am breaking ground on an 8 unit south of Sloan's in about a month - I am estimating $185 per foot again demo to door bell.

Same with my real estate lawyer - the check reminder worked here though.Best one yet - prospective contractor for demo and rebuild (age 32), asked me (50) if I was doing this as a hobby ( total cost including purchase initially $1.5 million. ) Err no ... and he didn't get hired!

How would one even go about knowing there's a demo order on a house?

@James Yang Thanks!

Phase One (Demo, Framing) of the work has officially started yesterday Jan 19th 2020 they knocked that out quick, next Phase is bricking the full side of the home.

You start out with a list of "big jobs" (i.e. roof needs replacing, plumbing work for licensed plumber (assuming you pull permits-something I think you could get away with 10x easier 5 or 10 years ago not pulling them) electrical work for electrician, demo, drywall, . . . ) Yet, it seems like you'll also get to the point, nearing the end where you will have a long list of "little jobs" detail stuff, little fixes, details you didn't notice due to all of the major fixes needed before, etc, where having a single all around handyman type guy (or girl!)

Demo and cleaning will be done by myself and wife.
