Is it better to receive a property empty?

[Michael Lettieri]

I am buying a 4 unit property. Currently 2 of the 4 units are rented near but slightly below market rate. The owner stated he could deliver the units empty if needed. I do not plan on doing major repairs at the moment, maybe down the road. Should I take them up on their offer and have the property delivered empty so I can place my own tenants? Or should I leave the tenants in place and be happy that they are able to pay rent at the moment? Thank you for any advice.
