All MLS's are different as to rules and regs. In our MLS, one of the rules is that (sic) "you can't include an increase in your selling commission as part of the offer." (I'll be happy to share with you the entire rule upon request.) So if the SOC is only half of what you'd expect, what do you do?
How do you insure that your hard work is going to pay you what you believe your effort and expertise is worth?
A Buyer's Agency Agreement.
If you're not comfortable with these, you had better tell yourself that you need to feel real cozy with these agreements pretty quick.
The days of working on a hope and a prayer are long gone. If you show properties without an agreement, I don't want to hear your sob story about buyers! There's no need for it.
You're a professional - act like that.
