It’s always better to work with an experienced new construction home agent to help you work your way through the buying process because though the builder’s salesperson is very welcoming and accommodating, the on-site agent still works for the builder’s interest. Before you sign any contract, find an agent who is familiar with the neighborhood and who has experienced in new construction transactions, he would be familiar to several builders and their contracts. The buyer’s agent service is free and will represent your best interest.
