I know many agents have been coached to use a scare tactic that in theory a seller could refuse to pay any buyer commission, but that is an incredibly remote possibility.

I don't want that to happen to you, or anyone else, because regrets in REI can have a lot of zeros in their price tag.This is just someone's opinion on the internet, it's worth about what you paid for it. :)Wishing you all the success you can dream of!

And get those incredibly good returns?

At that price point, your renter pool is incredibly small.
