I've got a contract on a small apartment building in DC that is partially occupied. I'd like to eventually facelift the units and raise the rents. I'm aware of the TOPA requirements, and I have clauses in the contract that the seller must provide copies of leases and security deposits. It will fall under the rent control requirements for DC. Any advice for other actions to take to ensure a smooth handover and/or tips on how to encourage current residents to move along so that I can remodel and raise rents besides buying them out?
