If it is an FHA and you meet the criteria for the assumption, then you can probably prioritize trying to assume the original mortgage first and paying the Seller the $50k.  

Thank you,  the lease states that The tenant agrees that the Landlords, their agents, servants, and contractors, shall have the right to enter into and upon the premises, or any part thereof, at all reasonable hours for the purpose of examining the same or making emergency repairs and alterations as may be necessary for the safety and preservation thereof.
