In my market, we're seeing a shift from a pre-agreed upon % to provide to a buyer agent to sellers offering buyer agent compensation but leaving it up to the buyer to request how much. 

(if the buyer wants a more solid commitment)Once a buyer has spent money they are somewhat vested in buying the property and that gives additional negotiating power to the seller.

I had a similar idea (having one of the mortgage brokers I know underwrite any prospective buyers.

Steps: you go under contact with the owner of the property, you assign the purchase and sale agreement to the end buyer, the end buyer closes, and you get paid the difference between the agreed-upon price between you and the owner and the intended purchase price of the end buyer. 

Like I said I have the buyer ready to buy. 

Oversimplifying it just a bit, the investor profits from:- a non-refundable option paid by the tenant-buyer which gives them the right to purchase the property within their option period- the spread between the rent paid by the investor to the property owner and the rent paid to the investor by the tenant-buyer over the life of the option- the spread between the price ultimately paid by the investor when they exercise their option with the owner and the price ultimately paid by the tenant-buyer when they exercise their option with the investorClear as mud?

It will familiarize you with the basic terminology and benefits.

All buyers and sellers of rental real estate should require Tenant Estoppel Letters in their contracts.

Seller-financed note buyers are looking for a 9% - 14% return. 

James and his people who manage the program are nice and give basic sales and negotiation advice but not much that moves the needle in any situation.
