I am a realtor. Here`s some questions to ask yourself:
-What are the real as opposed to the perceived benefits of having the sellers agent act for you as well ?
-Can you distinguish between the perceived and real benefits, honestly ? Are you guaranteed to get it cheaper, faster, better than the rest of the market ? If so, how do you know ? Because the seller`s realtor tells you ?
-The very fact the realtor is getting paid double the commission (unless you negotiate otherwise) means his objectivity is immediately at risk. This is just human nature. Therefore can he really be expected to put his interests (the double commission) completely out of mind when he is acting for two parties with differing desires ?
-Based on the fact he is getting double the commission have you asked him for a rebate on your side of the commission ? He could rebate you some of that (even though the seller actually pays it) ? Get it in writing. You don`t have to.... but some extra dollars in your pocket won`t hurt.
-Has he explained the valuation analysis of the property in detail so you understand his evaluation clearly. Do you have a copy of it you can take away and study ?
-Have you asked him what potential issues about the property the seller and he must disclose to you as well as those issues he cannot disclose ? The list of problems can be long. Are you being provided with a Property Disclosure Statement that is incorporated into the contract ?
-What is his relationship to the seller...friends ? old school buddys ? worked with several times previously ? Be careful here. You might not know if the realtor and seller see you as an easy target.
-Don`t tell your realtor your bottom line until the absolute last moment so he doesn`t `short change` you to the seller.
-Try a verbal offer first (although it`s not binding until on the contract) to see if the seller and realtor are serious. Doesn`t harm to keep realtor and seller guessing to see how desperate they are to welcome you in at a good starting price/terms.
- Be clear on the types of dual agency such as Dual agency, Limited Dual Agency and No Agency. You will also want to review the dual agency contract with the realtor. Make sure you have time to read it.
-Get an inspection and make sure realtor is present.
-Use your own lawyer, not the same lawyer as seller.
Just bear in mind that dual agency is a significant source of lawsuits.
Good luck. Keep us posted.
(Just for the record I don`t do dual agency at all-I only serve one client at a time, exclusively)
