Current Tenant Wants Lease Purchase Option

[Spencer B.]

My current tenant of 1 year has shown interest in purchasing the home.  She has been an excellent tenant and has good financials and seems to be a good prospect for a Lease Purchase Option.  I have read on some of the other threads on the Lease Purchase Option and understand how the concept works, but just wanted some feedback and direction on finding the proper forms and how to handle it so that as the owner of the property, I am covered.  She is good with the terms below:

$5,000 down

3 years

$100/mo Rent Credit

Purchase Price: $155K
