If they do not leave after 30 days you can serve them with a 3-day Notice to move out and you can file for eviction.

They might recommend that general listings can be obtained with the D&B file.

But does that mean I have to line up a job in that new location i find before I can secure my loan?

You should file to get a judgement for the unpaid rent and other outstanding bills (if Rent is not paid, I assume water is not paid).

The sum of cash I have Is not for the down payment but for the security of the next 6 months after the purchase. 

Hey Joseph,Congratulations for thinking of starting at your young age.To get a loan, find someone in your network who believe in you: Family, friends, etc. who is willing to act as a guarantor on the loan, if you cannot secure it yourself.You would have to come up with some capital to put down as a down payment.

One of my companies was able to secure a cash LOC without a PG a few weeks ago.

The eviction will be dismissed and will need to be re-filed by the new owner Keep in mind an eviction is styled:Current Owner vs Tenant You as the new owner cannot change  the plaintiff nor can the previous owner be awarded possession of a property they no longer own

Other agents do not hesitate to go to real estate bureau filing complaints to remove someone's license. 

I plan to file a complaint with the license board Monday and file a claim against his bond.
