I would like to see if the realtor costs I was quoted are good or too high.

Not a "Realtor" ®   but 15 years of high level professional Real Estate experience.

Realtor Fees in Texas are completely negotiable.  

Seller (You) typically pays 6% of your sales price (which at closing is then split at 3% to Buyers Agent & 3% going to the Listing Agent (yours).

A number of companies (New Home Builders) did a "move up" where they paid 3% to your agent, who could then sell your house for only 3% commission out of your pocket.

You can also pay "flat rate fee (I'll sell your house for $,1000!!)", "expenses + certain %" or a number of other creative options.  It is all negotiable between what you & the Realtor agree to.

There are some legal restrictions on commissions & payments (rebating outside the deal or paying unlicensed 3rd parties) but pretty much it is whatever you agreed to.

Only comment I have is do not ask or use Stanly Miller worst fucking agent in the state.

Selling?  Put it on your town's FB group.   "Hey! Just letting you know I plan on listing this 4 bed, 3 bath in 2 weeks.  LMK if interested. If so, we'll go through a RE attorney. Do not bring a RE agent, unless YOU are paying them their 3%.  If you are from Cali, NY, or IL, there's an extra 20% tacked onto the highest OTHER offer I get."

You'll sell in 5 hrs.

Does the Avila family count?

Have you personally done this?

No, but I have seen three on the closed FB group "flower Mound cares". People openly inquire, "Hey! we are moving to FM in a few months. Anyone want to sell their house?"

We plan on doing it when it is time.  And I WILL have a 5% surcharge for anyone moving from IL, CA, or NY to here.

I dunno but I can tell you there are some real agents here
