"Before learning about CoBuy, we went to see a lawyer to learn about the legal logistics. We left his office feeling more confused and discouraged than when we went in.

CoBuy has helped us smartly consider our options in joint ownership. We have peace of mind knowing we’ve covered all our bases and have contingency plans for all the what-ifs life can throw your way.

Highly recommend!"
