Case Studies

Personal Testimonials

Linda helped us with purchase of our first home. She is friendly and very helpful and we were able to ask any question as she wanted us to understand the process fully. I would be happy to recommend Linda to anyone who needs professional yet very friendly approach to something like house purchase.

Mortgage Advice

Linda was extremely helpful when we were buying our first home. As we were so new to everything, she explained all aspects thoroughly and easy to understand (for the clueless…me!) Linda is also very friendly and approachable to ask any questions, big or small, and dishes out some great advice. Linda is now my first port of call for any financial advice!

Financial Advice

Linda has helped us with our mortgage twice now. She reviewed our insurance and made sure that we have a will in place. She is approachable, her knowledge is amazing and she keeps in touch so I know I can always count on her. Thank you so much Linda!!
