State of Virginia. As of August 17, 2024, Virginia requires buyers and their agents to sign a written brokerage agreement before touring homes together. The new agreement includes buyer-broker agreements and listing agreements. I also know one does NOT have to have a realtor to buy a house in the state of Virginia.
You can make an offer on your own. You don't have to deal with a realtor.
The assignor must agree to assign their rights and duties under the contract to the assignee. The assignee must agree to accept, or "assume," those contractual rights and duties. The other party to the initial contract must consent to the transfer of rights and obligations to the assignee.
