Selling House, Tenant Owes Back Rent, No Leverage to Evict Now...

[Julie Bretton]

Buyer is requesting rent rolls on 11 unit building. I have a tenant who is behind on rent but is now paying rent and making monthly payments.  Once the house is sold, the 11 months of catch-up payments will probably stop and I'm out several thousand.  

Can and would a buyer ever want to "take over the debt" to evict this problematic tenant?  (Tenant could suddenly "find" the money to avoid eviction and I'd get paid).  

Am I better off giving the tenant a "personal loan" - and take tenant to small claims court if he defaults?  If I give a personal loan and take on the debt, do I have to disclose that the tenant is behind? 

I don't want to ruin the sale.  Any suggestions?
