Michael is correct, you can go to the Virginia SSA, but I prefer to go directly to State Statute for the most accurate and up to date process. 

Florida has a Specific form, and it is available in the Florida Statutes, just google it up.  

I'd start with the abandoned property statutes.

In North Carolina this can simply be terminated with a 7 day WRITTEN notice (see the attached for the legal statute). 

.—(1) When the department has probable cause to believe that any person not licensed by the department, or the appropriate regulatory board within the department, has violated any provision of this chapter or any statute that relates to the practice of a profession regulated by the department, or any rule adopted pursuant thereto, the department may issue and deliver to such person a notice to cease and desist from such violation.

@Brian Winn, Sec 1031 is a federal statute so any experienced national qualified intermediary can help you.  

Below is the Colorado Statutes on this matter:(1) A landlord shall, within one month after the termination of a lease or surrender and acceptance of the premises, whichever occurs last, return to the tenant the full security deposit deposited with the landlord by the tenant, unless the lease agreement specifies a longer period of time, but not to exceed sixty days.

I'm looking for information about the rules and laws around the foreclosure statute of limitations in Florida.

As to the law in BC, no clue, but check the statute carefully and they may view a release in the same light if a buyer is really "in the business" of pulling off such transactions. :)

However, in the event of a lawsuit you would lose some or all of your statutory defences, and might even be successfully sued for treble damages under the statute of fraud.Utilizing a structure of purchase contract assignment would somewhat disguise the brokering activity, and lessen the threat of a lawsuit.
