A pre-listing inspection by a licensed, professional home inspector has many advantages.
Your home will sell faster because you will bring more buyers to the table. Their offers will be based on the actual condition of the house. Therefore doing away with the need for conditional contracts, worries about the deal falling apart due to the buyer's inspector finding unforeseen defects, and 11th hour re-negotiations.
You will have more control over when the inspection is scheduled. Giving you time to correct any issues without stalling, or even possibly ruining the deal.
You will also reduce your liability and have more peace of mind, because you have engaged a licensed professional to disclose the condition of your home.
