Every property may be eligible for our Cash Back Rebate. Since we’re paid a commission by the Seller, we have decided to share in those proceeds since you’re just as busy and active in the search process to find your new home.
The full 20% Cash Back Rebate applies to new construction homes! New Construction Homes have special requirements that must be followed in order to qualify for the rebate. you MUST bring your BoldPorch Agent with you or potentially forfeit the rebate. This is due to the Builder and their representatives who may not honor our relationship.
