The grand theft statute refers to "property," but that doesn't necessarily mean real estate. Fl. Stat., Section 812.012
defines property as "anything of value," which includes money. Grand theft vs. theft is based on the value of the items allegedly taken. Anything worth more than $300 is grand theft, as is theft of firearms or a couple of other items, set forth in Section 812.014(2)(c)
A judge has discretion to allow or deny bail. Bail will usually be denied if the judge believes that the person is a flight risk. If someone has ties to the community, including a job, family, owning a home, etc., that makes it more likely that the judge will allow him to bond out. If someone is accused of stealing a lot of money that wasn't recovered, the judge may worried that he will take that money to flee the state and could deny bail on that basis. But bail isn't automatically denied for theft charges.
Grand theft in the first degree is a felony of the first degree, punishable by up to 30 years of imprisonment. Grand theft in the third degree is a felony of the third degree, punishable by up to 5 years. There are no mandatory minimum requirements in the guidelines. If the person is ultimately convicted, any time spent in jail awaiting trial is counted against the sentence imposed.
