Remember that it's your money that you're entrusting to a stranger, and you're not obligated any more or less because they wear the uniform. 

Most of us are pretty suggestible and will respond to a stranger's house with conscious and unconscious opinions about the furniture, the smells, whether it looks happy or sad, etc.

It's not complicated, Stranger-Danger is real, in everything. 

Think again, who the hell wants a stranger lurking around their house several times a week?

I'd really like the ability to solicit strangers.

Some are family members that would never lend to a stranger.

My dad has been a salesman his whole career and the advice he gave me before my venture was before i was to talk to a stranger to think of one of my friends and talk to the stranger as if he/she was my friend.

I don't know anyone who would fill out information and send it to some stranger without seeing the property.

@Matthew Anderson is correct - not the issue I would be taking advice from strangers on the internet. 

If he will even provide real financials to a stranger, it might take quite some time for him to collect them; we could risk losing out to a competing buyer/broker.
