Occupied Rental that needs Renovating

[John Maynard]

I'm a new investor looking at a 3 unit building to purchase that already has 3 tenants. Each unit needs rehabbing, so my question is: each unit is rented with the current owner month to month. I want to purchase the property and start renovating one unit at a time to not only increase the rents to market value, but also add overall value after the purchase. What do I do with the current tenants?
