As a Realtor that actively gives my buyers a 1% rebate, let me break it down to you like this..... MOST Realtors will tell you rebates either don't exist, you get what you pay for, agents would be crazy to offer it, bla bla blah. If you are one of the few top performing agents making millions per year, OF COARSE your not going to discount your services. Now for the rest of us....
87% of Realtors fail, mostly because they have no new business. We have all heard of 2/3 of something is better than 100% of nothing? I decided to redirect my marketing budget and essentially allocate it to the rebate. Since I have started giving my rebate, my referral business has increased dramatically, and its an easy sell for me when Im going up against "the other agent" who says "rebates dont exist!"
Just closed on a $500K condo, gave the buyer over $4K towards closing costs!
As to your question, I would not expect more than 1% rebate; It will be credited towards closing costs and on your HUD1 statement. I dont think any agents want to show 30-40 properties, but with the internet and tools available you usually dont need to actually view that many.
I would offer to help, but you are a bit too far for me to drive :)
