However, I seldom got such information from my buyer's agent (i.e. if it can be found via mls)and I tried to ask my agent to get those documents from the seller's agent.

Last year I posted an ad on Craigslist about something similar and mentoring/teaching people investing basics or how to make money in real estate with little to no money.REIBlackBook has a cool bird dog tool that gives bird dogs a portal to enter properties to keep track.

I have a number of properties that I have owner financed in the past and was wondering if anyone knew of a credit repair person that could help some of the buyers so that they could refinance?

Lender funds arrived 9/12, Buyer funds arrived 9/13.  

It all depends on if there are other hungry buyers.

I am always looking to expand my buyers list, so if you are looking for deals message me and I will inform you as new deals come in.  

@Jorge Ruiz True, the neighbor house put in very basic materials for their rehab, carpets in the bedroom and basic laminate flooring throughout.

If the seller takes a mortgage from the buyer, the seller calculates the gain as if he/she receives all the money when the sale takes place, then the seller picks up a percentage of the total gain, each year equal to the cash received each year, divided by the total sales price.  

I would recommend that you sell the property for as high you can as long as the market will pay, while at the same time leaving just enough margin for the end buyer to make a the deal profitable for themselves and be happy at the end of the day.I see many newer investors leaving money on the table because they think small and sell the properties by asking themselves " how much would I be content making on this deal?"
