Samantha S

Todd and I would just like to say thanks again to you and Mary Grace for all of your hard work with our construction loan application… That one certainly wasn’t straightforward. I’m sure Todd and I would have been forking out 10K in mortgage insurance if anyone else was our mortgage broker, and we can’t thank you enough for helping us avoid that. You guys are legends! Thanks also for the yummy edible blooms, those won’t last too long in our household haha! We will give you a break from us for a few months now… We will need a small car loan at the end of this year, so we will touch base with you about that then. Cheers and thanks again, Sam and Todd.

Martin worked tirelessly with us and the chosen lender to achieve settlement! It was challenging at times especially in this new lending climate but Martin was thorough and with us every step of the way. He updates us frequently and we would not hesitate to recommend him and Smartline time and again!

Miriam was our mortgage broker 7 years ago and got my husband and myself into our first home together. 7 years later, Martin has helped us build our forever home. We can’t thank them enough for their fantastic service and dedication to our mortgage needs. I’m more than happy to recommend Martin and Miriam to my friends and family.

Miriam was delightful and efficient to deal with. Even though in a different state, each contact and response was reliable and fast. She is a very good communicator, and informed us early of the documentation and steps we would need, so that all transactions were easily dealt with.

I am surprised with the fantastic rate that Martin achieved for us (3.81%!) assisting us with the purchase of our first home. Martin was always easily contactable and would call back as soon as he was available to talk. He was always positive and willing to help even when it looked like we might not qualify for a loan. I have been recommending Martin and Smartline to my friends who are in the market for their first home. I will definitely contact Martin again for any refinancing or new mortgage needs.

Martin has done and continues to do an excellent job looking after us in our purchase of our first home (construction). He explained processes involved with patience and provided resources to assist our understanding. We loved that Martin was tech-savvy and would look over our documents as we collected them and uploaded them to a shared folder. When presented with a discount from the vendor on a parcel of land, Martin worked hard with his team and other relevant parties to make sure we made the deadline to receive the discount. We cannot fault his effort or attentiveness in providing an excellent and trustworthy service.
