Owner Fi a Flip Property???

[Laura Engel]

I've had a very interesting proposition for a new on the market, higher end, flip property.....A buyer, due to personal issues, has bad credit - but cash in hand. They are asking if they can buy the house using Owner Fi.  They are offering a large down payment and to payoff the loan within a year. 

Apart from really wanting my money out of the house, what are the downsides here??

And as this is my first one, what is the process - have them get "qualified" by a RMLO before or after signing or negotiating....... 

Any and all insights are greatly appreciated!!

Thanks
