The contractor depends mainly on the area, and depth/need of the jobs.

If you want to get a more in depth report hire a structural engineer to inspect the home. 

Yikes, this is quite a ways out of my depth, but I did have the good fortune meet a very good real estate focused accountant who is based in Edmonton.

Thanks for the in depth response.

I may have to see if the tread manufacturer can give me an 11" depth tread. 

Make sure you do your own homework the numbers given by the seller are usually manipulated in some way. 

I talk about in on Bp 373 in depth.

@Justin G. nice post, I think it is important for the team or GP to make sure there is an open line of communication and be available for the investor whether they have a simple question or a more in-depth one.

I totally understand the time restrictions, but also think it is unethical for a broker to expect my company to show up on-time and then have to hang around one or twp extra hours because there are representative from two brokerage firms at the property, the seller is at the property, several other companies are there doing inspections and I have to be polite and stand around for 1 or 2 hours waiting find out who is who while multiple groups are having in-depth conversations, I have to wait to find out what they want, where things are at, get permission to move things, get permission to open things and then can't get in a word to discuss my inspection.When I see one other person at a property that is for sale I walk away because there is a lot of straight out bullsh..., promises and lies at home inspections.

This is just my rule  but in depth analysis on the BP Calculator will dial it in more.
