We are in a similar spot right now in our rehab biz, successful first two with some work completed by my hubby but now looking to systematize  and pull him out of the day to day.

Your GC should be able to crawl up in the attic and quickly assess wether the structural members are ok. 

You can spot these deceiving types by their advertising, "learn the secrets to" stands out and is probably the most abused, as real estate transactions, methods and strategies go back in history.

I would imagine I wouldn't make an offer on the spot because I have to run numbers once I figure out all the costs of rehab etc.

The very best way to get along with Realtors is by understanding their role, what they are obligated to do, what they can't do and don't ask them to stick their neck out, don't put them in a spot with you or another client.

This will help prevent light spots between sprays.

However on move in day the carpet was not cleaned and walls were literally spot painted in different color paint!

I had a talk today with one of my commercial guys; there's some blind spots in my knowledge base of the location.

Most of the properties we sell are purchased by buyers who already own property nearby the one you are selling.You can get a list of properties for sale in the regular spots like zillow and trulia or dig deeper at the county.We find tons of buyers for our product type at landwatch.com and landandfarm.comIf you are wholesaling homes, look for the we "buy houses people" in craigslist.  

Any less is a slow part time crawl up that most never end up making.
