How come you are fearful of asbestos...he seems to be a nice enough guy...haha. We have a fellow here named asbestos.
Asbestos is in a lot of remodeling demolition projects usually dated back to the 60's and before. I'm sure you know all about it with your user name. There is always the chance of it around...even on a job with none you can see. You never know who took it out of use in a house where it was used previously. If it was not professionally done there is always a chance it is still kickin around in the basement or crawlspace or walls waiting to be found.
If you where to stay in homes which are in new built areas, you may be able to stay busy. Just forget about building in New England, We have tons of it around.
Good luck in your endevors.
