Miles for real estate transactions used to be a pretty big thing. When I bought a condo in 2006 I earned six figures in United miles for being referred to a realtor. Basically they were rebating a bit more than half their commission in the form of United miles.
People usually think that meant I had to work with whatever real estate agent was assigned to me. That’s not the case at all. Instead, I simply needed to work with the brokerage firm I was referred to. I didn’t think much of the first agent I got, so I had the brokerage manager re-assign me to someone far sharper.
