I'm a licensed general contractor it is the career I've chosen out of passion and acquired knowledge.  

I'm wondering if people take their chosen vacancy factor into account with this rule?

@Jason Munck interesting that you've chosen to invest remotely in Spokane.

I do realize that price may vary by company and state but a ball park on these charges would be helpful when having to decide what type of closing to choose.If a double close is chosen and its an occupied home, wouldn't it backfire on the wholesaler if he/she is trying to keep the seller and end buyer apart.

If you had the ability once graduating to make 100k to 200k a year starting out in your chosen profession that is different.A lot of people rack up student debt and then can't get a high paying job and are stuck being underwater on loans.I don't know if the area you are looking in that multifamily trades at 150,000. 2 doors would be 75k a door in price, 3 unit is 50k door, 4 unit is 37,500 a door.

I've chosen a model that combines both

I can tell you what I have chosen and why.

Will he find satisfaction in his chosen field?

It seems to me that in an instance like painting or roofing, where the homeowner is specifically prohibited from choosing their own contractor or doing the the work themselves, that the HOA takes on the responsibility of the outcome of its chosen vendor's actions.

I don't know much about your chosen niche but I wish you the best of luck!
