Eviction of Buyer, or Foreclosure?

[Account Closed]

PM client has a Contract of Deed with a tenant-buyer who made monthly payments for 1 year for the condo living in, with 29 years left til owns, but since 2 months has defaulted and is refusing to vacate due to severe health and disability woes. Condo HOA does not allow any rentals nor rent-to-owns.

Seller/Owner wants to know if to use eviction/holdover proceedings to reposess, or has to foreclose? Not a lawyer, and this one's not my account and so out of my league anyways. Referred him to get an attorney but am curious as to the procedure nevertheless.
