Owner getting house back after it's bought in a tax lien?

[Suzanne Ludlum]

Hey Florida investors...please remind me what it's called when an owner loses his house in a tax lien and then has a period of time to pay the taxes and get it back.  It's sort of like a "making good on my taxes" allowance. Can it be sold to someone else during that time?  If so, can the owner still reclaim it? Thanks much!
