Hi Mary, I hope you are well. I note the new tenants have signed the lease for our property at Challenger Place Birchgrove which is great news. Just a quick note to say a big thanks to you and the team for the effort you've put in. Your team has been fantastic all year, but especially over the last month or so while we've had a change of tenants. You and the team have been great at getting ahead of even the smallest issues and resolving them quickly and without fuss. It's been so reassuring to know the team have everything under control at all times - they have not missed a beat! We've worked with a few property managers and the quality of service from your team is absolutely second to none. Thank you again Mary and please feel free to pass on our thanks and appreciation to the team. Regards,

Dear Mary K, Mary A & Anna, I am very pleased with the help and service you all have provided. I am renting for the first time whilst my property is being sold and was not sure what to expect but you all made me feel at ease and comfortable from the time I viewed the apartment right through to signing of the lease and beyond. Thank you very much.

Attn: Mary Karabellas and Mary Aidonas Re: 12 Cheltenham St, Rozelle Hi Mary & Mary, Thanks for your email and hope all is well with you. Mary A, thank you for your offer to continue to liaise with our new neighbour with regard to the home insurance between our properties. It may be easier for us to deal with them directly hopefully but I'll let you know and grateful for the offer. Mary K, thank you and your staff so much for all the great service since I had you lease my property many years ago. If we need to re let or sell you'll be the only agent involved. Really appreciate everything Mary, take care. Kindest regards. Sheree

I can’t keep up Mary. You set a blistering pace. You are a power woman leading all those beautiful women in your office. Thank you very much in leasing my property. Great to have it ticking over again – we got there, now you can sit back and enjoy the ride. Much appreciated. A great bunch of ladies. Cheers.

I would like to take this opportunity to thank you and Chris for the fabulous service I received on the sale of my property. Your suggestion of an auction instead of a sale gave me an amazing result. The way you put my existing tenants at ease and thus allowed us access to show the property without any tension and resistance, showed me that you really do care about the seller and tenant and made the whole process amazingly stress free.for us both. The professional service and detail you and Chris put in from the moment I asked you to sell my investment property was nothing short of professional and polished. I have known Chris and Mary for 15yrs as I teach yoga in the area and to ask them to sell my property was a natural easy choice for me and I highly recommend them. The integrity and attitude you run the LJ Hooker office in Balmain is known wide spread throughout the community by many. I was truly so impressed and thank you both and all the staff for the friendly professional service.

I thank you for the last 12 years, from the time your office sold me the property, through the years in between managing the rental, to the final sale settlement this week. It's not always easy trying to manage investments from a distance but you and your team have made it all the easier and relatively stress free. Once the Sydney property bubble has popped (my uneducated guess!) I may well be ready to dip my toes in again and will certainly be in touch if and when that time comes.

This is now the second time we have dealt with LJ Hooker. First time was when we bought our property in Balmain and dealt with Mary. Mary was also fantastic with helping us purchase the property as we felt there was no game playing, just efficiently helped us achieve what we wanted. The speediness of the team and the ability to deliver on promises is so important and we are so happy with your excelling customer service and ability to always keep us informed and involved. For anyone considering on a real estate agent we can only recommend one – LJ Hooker Balmain. Thank you for everything you guys have done for us and we look forward to continuing our working relationship with you.
