We're just about to enter our busy Spring selling season.. so every year I have to do a video on the 2 biggest mistakes I see sellers make and how it’s costing them ten’s of thousands of dollars in their final selling price. Those 2 mistakes are: 1. Selling a property too soon and not giving it at least 7 or 8 days on market before looking at offers 2. Selling a property with an existing tenancy agreement in place.
