There’s no catch! Whenever anyone buys or sells a home with a realtor they pay a commission to that realtor for their services. When you choose 2ROOFS as your realtor, a portion of their commission is donated to the partnering nonprofit you select. Donations average around 10% of the commission. For example, with the sale of a $350,000 house at the normal 3% commission, the donation generated would be around $1,050, which would come to Habitat for Humanity in Whatcom County if you choose us as your partner nonprofit.
