How to split a down payment?

[Juan Martinez]

I am selling a house and a friend of mine is offering owner finance up to $133k. I sold the house for $142k. The buyer needs a $9k down payment but they only have half of it at closing and the other half 30 days after. We are closing at a title company and they wont allow the second half of the down payment to be left pending? How can this be structured to protect all parties? Would a simple personal loan from me to the buyer be ok if we sign a contract? I know I am taking some risk but how can I take the least amount of risk? I am in Texas.
