Assume this is to a buyer agent.
For buyer's agent, their responsibility is to locate an affordable property to meet your requirements.
Before showing a house, agent should study the neighborhood general information and local house market condition. When showing a house, agent bring buyer to view the neighborhood, street first, then the house itself. For the house itself, besides point out the superior side, more importantly, agent shall point out inferior or potential problem side also. I don't want to make this post to long to read. Anyone has particular question about the procedure to view the house, please QQH to me.
But for the first time buyer, agent shall educate them first before searching and locating any house for them. Let them know the current local market condition. Is it buyer market or seller market? What's the interest rate situation (But don't quote rate for them)? WHO THEY ARE COMPETING WITH.
When searching or showing a house, agent shall be aware is there any unusual, untypical or too good to be true phenomenon. Once that happened, always raise a redflag to the buyer.
During the offer and negotiate process, agent shall proposal a offer price below or above market value depends on market condition and buyer intention. Offer price is very important. But price is not everything. Other term does count too. Agent shall present buyer best credibility capacity as well. I always prepare a unique cover letter to state: Our buyer is very interested to your home and have very high credit score (most Chinese buyer have 700 or above ). We have a pre-approval letter from a major direct lender. Our down payment is ready. We can close the contract on time or early. On the other hand, carefully set the all contingencies in the contract to protect the buyer's interest.
If the buyer have some urgency to get this particular house or have a deadline to buy a house (e.g relocate package, 1031 etc), then you have to fight with other offers, raise the bid, increase the down payment, AS-IS term or waive some contingency.
