Seller of 9/1-3 Baird Street, Kearneys Spring
I have now both purchased and sold property through Mark Costello. When it came to selling my unit, it was a no brainer contacting Mark to be the selling agent. Still, I was blown away by the result. Sold well above asking price, multiple offers, and under contract after just 1 inspection. There were certainly bumps in the road (no fault of Mark or any of the iThink team). From tricky buyer requests, to bond cleaners who didn't show up and even taking care of my cats during inspections; nothing was too much of an ask. I would have been lost without Marks help, and certainly wouldn't have had such a smooth sale. If you want someone to take selling your home seriously, and who goes above and beyond every single time, make sure you call Mark.
