Quote from @Luis Herna: Let say I am a licensed real estate agent in oklahoma and there is one buyer in new York wanting to buy a property in Texas.

There are more buyers for SF homes, but Multifamily properties typically cash flow better as you mentioned. 

What you are describing is a "dual agent" role, where the agent represents both buyer and seller.

Yes, the buyer, not the buyer agent. 

In the event that a seller was to owner finance a property to a buyer without a SSN, is there a market for the Note to be sold to a note buyer?  

Buyers?

I'll quote the book, in the section how to vet buyers from fake buyers (other wholesalers)."

I negotiate at 70% ARV so the deals I bring are solid and I'd love to work with one single corporate cash buyer that is able to close  on several deals a month.

You can't negotiate directly with a real estate agent about hourly rates because that's up to their brokerage.

We've sold 65+ homes and the biggest request we get from our Buyers is help with closing costs.Most of our deals we're providing anywhere between $5K-$10K to help Buyers offset the cash requirement to purchase a home.Even in today’s "high" interest rate environment, many Buyers prioritize closing cost assistance over an interest rate buydown.
