Evicting Tenant after buying 3 Family (with Tenants)

[Robert P.]

I am in the process of buying a 3 family home with tenants in each of the units. I have financed this through FHA, so it needs to be owner occupied.

My plan when buying was to "figure out" each tenant as much as I could and choose one to evict so I can move in. Now that I have chosen one, with closing in less than 2 weeks, what is the best way to get that tenant out peacefully?

I know there are general laws and notices, etc which I am very familiar with, but what would be the best way to get them out. Should I just serve notices, talk to them about the situation,etc? I feel bad that they will have to move out so quickly, but there really isn't much that can be done. 

If I have to go to court, will the judge be more on my side since I bought the property with owner occupied clause, or is it the same deal?

Any insight would be helpful. Trying to figure out the best way to get them out with out too much trouble and costs.

State: Massachusetts
