The appraisal has to be done by the third party, the house cannot be sold in an unreasonable price. The property tax is based on the sale price, got it?

The seller's agent only represents the seller, you donot have to have an agent. If the seller already signed a contract with hhis agent, I do not think he can get rid of his agent and sell you the house (so called "sell by owner").

Because the seller have to pay 3% to both agents, so what you could do is asking the seller drops the price by up to 3% if you do not selectany agent.
