We had cut it fine by buying before we sold and then COVID hitting, which was a very stressful situation. Rob was brilliant, right with us through the whole thing working hard to see us through it with a good outcome. Fantastic to deal with.

We have been dealing with Lou and Robert Costabile for years, Rob handled things for us this time round and did a fantastic job. We were able to secure what we needed and more. With the delays due COVID-19 Rob’s communication was exemplary. Top Job!
