NOT by tenants but owners who are full blown horderslast 18 months I demo 'd  6 houses that were lived in for years and were just beyond salvage..   

The big ticket items were obvious so no real surprises. 99% of the time when you go over budget it's usually because you change plans mid flip or something is uncovered during demo (rot, plumbing issues, structural and so on) .

I assumed I'd handle the demo and electrical portions but am interested in what everyone thinks as far as what specialty "pays" the most to be proficient in when it comes to doing the work yourself, assuming the quality of work is on par with contractor(s).

It'll cost you around $10k for demo and I'm not sure what the cost would be to build a similar-sized house on the lot (maybe $70-$80k?) 

But for someone trying to keep an existing faucet, he would pay a $200 difference in cost plus demo/uninstall labor. 

If you want brand new stucco and lath, you would have to demo out all of the existing stucco and lath, and introduce a new stucco system.

By class here are my pics.. b class I like Hubert heights and Kettering and north shilohB minus the nod goes to southern shiloh, belmontc plus north riverdale emerging parts of north DaytonC eastern hills, old north daytonC minus, north main - dayton proper, westwood (yes it did get that much better after a thousand demo), trottwoodD Salem ave - Dayton proper, five oaksF Santa clara

Sounds like a 5k job for me with permits, excluding putting back drywall and no extensive demo work.

Don't forget that you may have to get a demo permit in many areas,"This section highlights OSHA standards, standard interpretations (official letters of interpretation of the standards), and national consensus standards related to demolition.OSHANote: Twenty-five states, Puerto Rico and the Virgin Islands have OSHA-approved State Plansand have adopted their own standards and enforcement policies.

For me that includes demo of old siding, vapor barrier, etc.Obviously there are many things that affect price including type of siding, two stories ?
