$10 consideration for the transfer was not the price. The property is undoubtedly subject to a loan.
It may not have been subject to a loan since it was only quit claimed. The lender, if one was involved, would have had to sign off on the transfer and a lot of times they won’t do that on just a quit claim deed (they’ll require a general warranty deed because of the potential liability in the chain of title). You are absolutely correct on the 10.00 though—that has nothing to do with the sales price. However, if it’s revealed eventually that this was a huge plot and he transferred it in order to avoid pending litigation then it may be deemed a fraudulent transfer—depending on what Florida law says, and I have no idea what it does say. For instance if he was planning on filing for bankruptcy and transferred the property like that, the bankruptcy court would void the transfer. Anyway you slice it, it’s fishy.
