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.

Buyer of 36 Rob Street, Newtown
As I work in the north west of Western Australia as a FIFO and the current pandemic that is going on, this purchase was rather trying at times and was all contracted and purchased while I was stuck in WA for work. I didn't get to meet David but spoke a couple of times over the phone, Angela showed us through the house and a bit of corresponding through emails. Both David and Angela was very honest from the beginning about what was wrong and what needed doing with the house, they where helpful when it came to referring and any questions about the property. Also due to the difficulty's of the situation was able to extend the settlement date a couple of times for us to give us time as getting paperwork to me for signing on a mine site was time consuming, plus other little difficulty's that presented was met with understanding and helpfulness.
