The only exception is if the tenant does not cooperate with the treatment process, they then become liable for all costs. 

I haven't spoken with him yet, I'm hoping that he will be cooperative in everything.

I understand I have cooperation with the daughter to finalize this transaction as it is ringing up taxes and HOA fee's in her parents names.

I'd want their cooperation in finding the cause.

We don't know that the tenant is being cooperative or not.

@Jaysen Medhurst  Hi Jaysen, I really appreciate that, I have been looking at foreclosure properties so the sellers are not so cooperative, but I will definitely try what you recommended.

If the defendant is cooperative, you should be able to have him sign something to enter his appearance, waived service of process and confess judgment.

You can let them know that your goal is to get it rented ASAP and that will get them off the hook for added rent when it vacant....so their cooperation would be greatly beneficial to both sidesIf its a good tenant and they are leaving for a reasonable cause, I try not to be too harsh.....make arrangements to get it ready to go ASAP and move on...

Has anyone purchased a property through Alex Cooper Auctioneers?

400K for a MFR is very difficult to find anywhere in the boroughs or LI unless you're paying cash and/or can deal with additional issues on the property- i.e. non-cooperative tenants, poor property condition, liens, violations, open permits, etc.Another option could be finding a partner to co-sign on the loan with you.
