Using your own agent is vital when buying new. Most people think that by going direct to the selling agent in re-sale or developer in pre-sale that they will ultimately lower the costs and that this will be passed on to them.   Doing this will ensure that you are not being represented.  Developer agents will sell you on over priced remaining product, in re-sale, agents will be confused as to whom they represent.  In either case you will negotiate a bad deal. Developers rely on the support and sales from agents.  Developers will not run the risk of under cutting the realtor public and being black listed, we represent over 80% of their sales. In the case of re-sale, multiple representation never works in the best interest of the Buyer, think about it, who is paying for the service of selling the property.  The price of representation is already factored in, the choice of representing one’s self is ignorant to say the least. I have a fiduciary duty to represent you in your best interest. With 15 years’ experience in the field working directly for developers, I have the knowledge to insert certain clauses, and I will explain the agreement of purchase and sale to you in a way that you will understand it. However if you are confident that you can do a better job than a Professional Agent who has a fiduciary responsibility to represent your interests and is schooled in the industry, than by all means go ahead.  With such confidence I would also suggest that this person write their Real Estate Courses and consider a career in the business.
