If you are looking at a listing data sheet here in Florida it means TLC/tlc (tender loving care) needs some work but not quite a fixer upper. If you look at the tax records and it indicates TIC then it would be (Tenants in Common) .
TIC is a type of ownership in a property. If property is owned by two or more people as tenants in common, then each owner will hold a percentage of ownership interest in the property. The percentages don't have to be equal. They are determined by how much each party/owner contributes toward the purchase of the property in question.
