Hi Bobby, I'm the ops manager for the Property Management Division at Milestone Premier Properties and a licensed realtor and investor.I actually live in Denton too butour brokerage is based in downtown Denison where I commute 2x a week.

Often times, there's houses or land worth $500k listed with an opening bid of $30k which is a fantastic deal; however, if you were to win the auction, there may be multiple liens and $100s of thousands of hidden fees that you have to pay at once (based on what I read online).

There’s just not enough ADU supply (IN MY AREA) for appraisers to base off of.
