If you're considering purchasing under a business name, consult a CPA or attorney for setup and financing options.

Contact a real estate attorney in the county the property is in and have them do a property ownership search and lis pendens (lawsuit) check.

New To the New Jersey Market, Good New Jersey tittle company that don’t need an Attorney present and familiar with wholesale deals?

There are attorneys who will help navigate the process for you and act as an orchestra conductor to keep things moving along.

But I'm not an attorney, so maybe I'm totally wrong on this hunch.My 2nd comment is directly within my practice area though.

Agree to allow the firm’s “entry level” attorneys handle your cases or as allowed by law their clerks?

I agree with the others here that say you need to have some skin in the game, if you are going to live there yourself, get an FHA loan rather than owner financing, you can get a 3.5% down loan, personally I do not love these as they require  PMI which is an additional expense, and you also need  bring additional funds for closing at least for taxes, title, attorney and transfer fees . borrowing from anyone else for the down payment, to include a personal loan from the bank is not a good idea, those again will be higher int. rate.

Then I would seek a legal consultation from a real estate attorney to assist in evicting them if they will not leave (we have a few great attorneys we work with in the area). 

In most cases, neither is warranted.Warning: I am not an attorney, and this can be a complicated topic.
