This is why they have systems and procedures.

Definitely make sure to handle this with caution; follow the state procedure for evicting a tenant.

Hello,For Massachusetts landlords or possibly other states as well, what procedures do you all follow if a TENANT on a month to month basis gives a landlord a 30 day notice that they will be leaving, but they don't actually leave at the end of the month?

If an eviction moratorium is in effect, that doesn't preclude you from filing the appropriate notices and following the proper procedures to get all the way to the doorstep of eviction. 

So i saw alot of videos on youtube of guys that have like 25 units in first year or some crazy numbers like that but often they dont explain loan procedure so i would like to someone to explain it to me if can.

If they can not or will not provide that I would let them know you will be going to the state real estate commission to file a complaint if they do not make things correct.Next I would be careful starting a business that is so litigious and process / procedure driven just because you have a bad business relationship.

My CPA is willing to try to help getting it set up but is researching the procedures.

Let them know the standard procedure and that you are planning to follow it.

Every state has different rules / procedures, but in some, once a property is sold at a tax deed sale, that is it.

But I completely expect that NY state has a similar procedure.
