There are alot of large volume producers that you can pick from down there. You should not have a problem finding one. Ask the ones you interview to bring you a list of recent transactions (that they have performed) for the area you live in.
Agreed big time with what cali said about advertising. Unfortunately we are not in the age where mailers and magazines sell homes.
The commission you pay covers everything. If they try to add ancillary costs (for instance you will want them to send a professional photographer to shoot the home) make sure you don’t get stuck with that cost.
You pay essentially two commissions, a listing commission and a coop commission (the CBB you referred to). I personally feel that 2.5% is a good cbb. As an exercise, as the agents you interview to bring you the breakdown of the cbb for the last 3 months of sales in the area. That way you can identify if there is a strong skew towards 2.5% or 3.0%. My guess is you will find that about half are 2.5 and half are 3.0.
You can try to negotiate that if the listing agent also becomes the selling agent (selling agent = buyers agent), then the CBB is reduced. Some listing agents will go for that, some will not. You can even be ambitious and try to say that if the selling agent comes from the same office or same company that the CBB will be reduced. Again, unlikely but you can try.
Essentially 6% is meaningless. Think of the commissions as independent and try to get each one as low as possible or at least one of them.
Pre-inspections are never a bad idea. Get a physical inspection, and a termite inspection. The termite inspection should be free. The physical inspection will run you around 400-600 depending on the size of the home.
Get the home on the market asap. Do not wait until May. I cannot stress this enough. You wait til May you lose out on the large pool of buyers who are starting to look for a home NOW. If that means you do a rent back or a long escrow or a combination of the two, then do it.
Make sure your agent gets a professional photographer.
