Primarily, agents work for themselves, real estate is a commission driven business. They want to close a deal successfully so that they can get paid. In general it’s in their best interests to try to close a deal with all parties as happy as possible (because happy clients are one way that agents get new clients). However, they are not praticularly motivated to tell you (as the buyer) anything that might queer the deal, and some agents will just push for a deal, any deal in some cases.
In PA at least, you have the option of hiring a “buyer broker” who is a liscened agent who is working for you, the buyer, and your specific interests under a specific type of contracted agreement. A buyer broker arrangement is currently much more the exception then the rule, and they have special rules governing them.
All buyer brokers are real estate agents, but not all agents are brokers. This same person you hire as a buyer broker may also act as a listing agent in other situations (what you might call the “seller’s agent”) but here at least, they are not allowed to work for both parties in the same deal.
If you simply contact an office an ask for an agent to show you properites, that person is not your buyer broker… they are just an agent who is working with you to look for a deal. The job of the agents is to bring the house and the buyer together, and make sure that the deal is closed properly from a legal standpoint.
At settlement, the commissions involved are paid by the seller, out of the money they receive for their sale. Commission is usually based on a percentage of the selling price and can be divided between the listing agent (who found someone who wanted to sell their house, making the deal possible), the buying agent (who found some buyers for the deal), and if applicable, the offices for which either or both of these agents work. In the end, it’s the seller who signs the checks… so in a way, the agents do work for the seller.
In your case, the sellers agent could NOT have refused your offer, she is required to present any and all offers to her clients. Only the sellers themselves can refuse.
It is also important to remember that sometimes the sellers have a lot of memories and strong emotions tied up in the “property” at hand. None of which means a hill of beans to a potential buyer. This sometimes gives sellers an unrealistic view of the worth of their property, and can make them a real pain to deal with for their agents. Sellers remorse is typical (most people rarely deal on a regular basis with $$$ as big as they do when selling their house, and doubt in their own desisions is ) If the sellers in your deal really want out, they have that option up until settlement is finalized, however absent fruad or legal issues, they will typically have to pay penalties (which they likely don’t want to do) for withdrawing from the deal unless they can get you to agree to mutally dissolve the deal. If the current deal is what you want, then stand firm and let the seller decide either to go through with the deal as currently set, or pull out and pay the costs.
If this deal doesn’t work out in the end, you may want to onsider hiring a buyer broker (or the equivalent in your state if available) before moving forward. You seem to be looking for more of that type of representation.
