In a state like FL is there a disadvantage buying on CFD vs...

[Benjamin Cowles]

... I still don't know what to call the alternative, the one where title is transferred. promissory note? loan agreement? either one + mortgage? so many terms and many interchangeable idk. so help with that would be appreciated.

to the main question:

I've read somewhere even with cfd's you need to record a mortgage because of something to do with FL being a judiciary state. And from my limited understanding the cfd is favorable to the seller as they keep the title so if and when buyer defaults seller doesn't have to get the title back but apparently in judiciary states a foreclosure is still required.  

So from the buyer's/borrower's perspective is there a relevant difference between buying on a cfd vs. the alternative(whatever it's called??)? Thanks!
