Possible descrimination against HOA owners

I hope you all are well doing what you all do best helping and educating all the members. Since I purchased a property in Fl it was know that one member could not own more than one apartment, to avoid speculators? Originally rental was very strict, today you can rent after owning the property for two years. Now we have a buyer that owns a property across the street, and resides on another property? They don't seem to be buying this one bedroom unit to reside, so we are thinking probably they will wait the two years to rent? We asked if this new buyer, is fixing the unit to go ahead and sell it for a profit? If that is considered speculation? They said no? I think that if somebody can do that why owner's cant?
