If you cut ties with one principal broker, you are unlicensed until you sign on with another.If your main goal is access to the MLS to work your own deals, you can find companies that just charge a transaction fee instead of take percentage of your commission.

Mainly because the comps aren't truly reflecting all the land in addition to the 2600 sq ft house.

My main purpose into educating myself about finances is to build wealth.
