Playbook for Foreclosure with Owner Holding Over in House

[Soo Y.]

A couple of questions for those who dabble in sheriff sales and foreclosures:

1. What is your playbook when the existing owner still lives in the house after you win at auction?

2. If you do cash for keys, how much do you typically offer and do you scale down as the time frame gets pushed out?  (E.g., $X if you leave in Y weeks, $X-something if you leave in Y+ weeks).  Fill in X and Y.  Bonus points if you could identify your geographical market.

3. Assuming the existing owner rejects your offer, relationship generally goes south and you seek judicial eviction/ejection, how do you guard against the existing owner destroying the house or stripping it down?

Finally, if anyone has done this in NJ, I would love to hear your experience.

Thanks.
