Do you know of any property, whether off-market commercial or residential, that could be leased by a church group. 

However, we always had in the lease that they must find someone to sublease to get out of their lease and are responsible for a $250 sublet fee and $50 turnover fee.

I buy using Subject To, Wraps and Lease Options and then sell to tenant buyers and I carry the note.

The new tenants are supposed to move in tomorrow and have paid first months rent with no lease signed.  

@Eric TanJust based on the limited info, I would structure a Lease with an Option.

They are on new leases with 9 months to go.

This will be especially useful if they decide later to ask permission for another family member to be added to the lease (sibling, nephew, elderly parent, etc) and you have already set the standard that everyone will be need to have a background check.

Perhaps when the lease is up for renewal and the child is 18 years old you could then do a screening but it may not make sense to if he or she is good tenant at that point and continuing to share a room with the leaseholder.

Depending on the bank, some will account for the cash flow within the first year if you can prove to them the length of your lease with a tenant and how much cash flow is obtained each month.

Then the buyer would agree to let the tenants continue to live there granted they sign a lease and start paying the going monthly rent, which depending on the condition of the house could be about $2000 - $2400 a month.
