Looking at wholesalers as a possible source of deals, but heard too many stories of things being done improperly during the transaction.

To answer your question about deliveries above, constables are usually the most reliable source to do this, from what I've found.

The money will still be available, but the terms will change.The sources for money are in the business of selling credit. 

List source is good for basic lists (absentee, pre-f, ...) but they don't really have anything when it comes to niche records. 

You need a good team, systems to source deals, means to fund deals and manage contractors, and a sales team to exit from them.

This provides a new capital source, but will also often turn into an informal coaching/mentorship relationship.
