^^^ This. Don't be shy about it. Each state has their own laws. In Georgia, the executor is basically entitled to 5% of all moneys that pass through the estate account from personal property and 3% of real estate.
You're entitled to it and you'll earn every penny of it. Ask the probate attorney about it and see what compensation your state allows.
If NM is like GA, and I did the math right that's nearly $16K. That's big chunk of change and more than realtor made!
