Wow, a whole lot of assumptions.
I guess the realtor commissions just dont seem that important to me when i'm doubling my money (or better) on a property, which has usually been my primary residence.
Doesnt take much of a salesman approach to call "help u sell" to get their 1.5% sellers fee and then ask them to set the buyers agent rate at 2.5%. Or if thats too much, call costco and go through their program and get a portion of the fees rebated to you.
Even my century 21 and coldwell banker agents will do a 4.5% total commision deal with no more negotiating than my asking "will you do it for 2%+2.5%?".
In selling my old house, it'll be darn near zero. I asked all my neighbors who among them knew someone who'd like to live next door to them and get the house at a good price. One seems to have materialized. The price we've tentatively negotiated is what I hoped to gross from the deal using a 4% commission, plus a couple of percent, plus they're going to paint and carpet it, which saves me another couple of percent. Hopefully the deal will go through as planned.
I realize this is an emotional issue and that a lot of people want to put their personal residence in a 'lock box'. As long as your recognize that you're boxing off what is probably your largest single 'holding' from working to your advantage, thats swell.
