Great team effort!

It is my pleasure to recommend Sinead, Jen, Nick & Elsa as a dedicated and highly effective real estate team. They recently helped me sell my property and their professionalism and expertise made the entire process sleek and painless.

Helpful but didn’t nag us

Helpful but didn’t nag us

Nic and Sinead went the extra mile to ensure we got vacant possession. This was an estate sale and there was a lot to clean and clear out at the last minute. The agents ended up closing this themselves on settlement day. The weather was dreadful and it was an unpleasant job for them. We are very grateful.

Tailored to my needs and very communicative

After missing out on one house in her area, Sinead's knowledge of her neighbourhood made it possible for her to propose a house that was not yet on the market and was an exact fit to my needs. Her team was always very communicative and responsive to my queries, and made the whole process easy. They made me feel very welcome in my new home. I would highly recommend her team.

Quiet Sale in Eastbourne

Quiet Sale in Eastbourne

What started simply as an appraisal quickly turned into a quiet sale with a sold sign up before we knew it! Sinead and Jen were both absolutely wonderful to deal with, so friendly, approachable and genuine throughout the entire process. Everything happened incredibly quickly, but we always felt informed, supported and in very capable hands. Thank you Harcourts Eastbourne team for making what could have been a stressful experience feel so easy and positive. We really appreciated all your hard work behind the scenes and so happy you found a new happy owner for our lovely Eastbourne home.
