What to say to exising tenant wanting to move into renovated unit

[Paul Chae]

Hello everyone, 

I have owned this quad since earlier this year. This one is my first multifamily property in central New Jersey. At the initial stage of renovation in one of the units, one of the tenants in other unit saw the rehab was being done and asked if he can moved to the renovated unit once the work is done. Eventually the request was rejected since it would only mean a turnover which I, as a landlord, want to avoid in general. I understand the tenant's motivation, the new unit is only a hundred dollar more expensive than what they are paying for their current unit. but planning on acquiring more rentals, especially multifamilies, I don't want to allow the existing tenant to move into the renovated unit, and the new unit will only be for a new tenant. 

Has anyone encountered this issue or similar ones and I would appreciate any suggestion on how to properly respond to such request? Thanks everyone!

Paul
