is there a place/registry in Florida where I can research an investor?  

Things will be a little different in Québec as they have both a different legal system and land registry practices from the rest of the country.  

Most have a registry of actions or similar clipboard with most recent filings. 

Also, just to clarify, when searching by name would this be using the registry of deeds site, or a different one?

I'll then cross reference the info to the towns GIS website and Registry of Deeds website to get as much data as I can.I am a member of my local Board of Health so I've gotten to know the ladies working in the tax collector and assessor's office pretty well and they've been an amazing resources for information.

You can search this registry to see if DEA did a "cleanup" of the property:http://www.justice.gov/dea/clan-lab/clan-lab.shtmlI've seen 20/20 or 60 Minutes episodes that showed the residual levels of hazardous chemicals present in structures used as meth labs.

Someone should create a bank registry with whatever their rules are so it would be easier to find lenders.

The rental registry program fee is $10 annually for sf and $20 for 2-family and is billed every January.

Also, were you concerned about the DoNotCall registry?

I do look at the Megan's list registry when buying property.
