I "released" two property managers.

Unless released by either party that money sits, no matter how right or wrong either side is!

Either way you go, make sure all work is done right and always get lien release waivers.

When this happens I have to give a 60 Day Notice to vacate, hope they leave and if not start evictions which could take 90 days+, then repair, release, etc.  

It's not unusual for an owner to refuse to release financials until an offer is made.

Likely, they accrue and are released at sale.Your best bet for calculating how much money you will make above the preferred return is based on the projections offered during the due diligence period.

I would recommend getting an information release form signed by the applicant in the case that the previous landlord needs the applicant's permission.

I usually let the tenants handle the security deposit between them and the person leaving signs a release for me stating they are owed nothing.
