The listing company has a relationship with the seller, not you. You are not required to use the listing company to see the house – you can use your own agent at no disadvantage to you.
If you call the number on the sign you will most likely get whoever is sitting at the front desk when you call, and they will offer to be your agent!
Companies prefer junior people to take these calls because they get a larger percentage of their commissions and make more money.
They will usually not pay your agent unless he or she is with you at the first visit. Builders do not like you to have an agent – they want to be able to control the process.
High pressure, unfair forms, hidden costs, and limited rights are common in new construction if you do not have your own advocate.
