Tammy was our real estate agent and she was amazing! God send. Moving to Austin from Cali, we had no
idea where to even begin. Tammy helped us narrow our search. We looked for months! Trying to find our
perfect home and she was there every step of the way. She’s patient, kind, on top of it and when needed
straight forward and stern. Well rounded. I can’t thank her enough! I know we weren’t easy clients so
anyone reading this looking for a realtor in Austin this is your sign. Give her a call. You won’t regret it.

Tammy Costello was a blessing to us. She assisted us in finding a rental when moving from out of state
and was so pleasant and positive during that experience. When it came time to purchase our home,
Tammy was amazing!!! She answered our questions with real honest feedback and the rare instances she
didn’t have the answer, she would tell us that she would get us the answer and then deliver on her word.
Never at any time was there any pressure as there commonly is with agents.
I can’t imagine going through the process with anyone else. Her upbeat attitude and kind character made
her so fun to be around!
