When a cash buyer makes sense in Port St. Lucie
A cash sale makes sense in specific situations: your home needs major repairs that make it unfinanceable for conventional buyers; you need to close in under 30 days due to relocation, divorce, or financial hardship; or the home has title complications that make an open-market sale difficult. If none of these apply and your Port St. Lucie home is in reasonable condition, listing on the MLS via flat fee MLS will almost always net more than a cash offer.
