Selling via Lease Purchase in Oklahoma

[Brandon Siewert]

I'm generally familiar with the lease purchase vs lease options and generally familiar with the risks.  I've seen a myriad of forms which are generally the same.  Where I need some advice or opinions are on the following:

Guidance on terms structure, dn pmt, monthly payment, length of initial term, owner carry at expiration or buyer financing, etc

IF Owner carry is an option at expiration, what has to be done to complete a wrap?

Specific Worst Case Scenarios

The house a mortgage balance of $63K, sell price is listed for $78K, current rental rate about $850, 3br, 1 ba, 1400SF

Any advice is appreciated.
