The BEST Agent!!!

The BEST Agent!!!

I used John Foster as my Realtor to sell a home in Cumming many years ago. For some reason when the time came to sell my current house I selected another realtor. When my home in Cumming GA did not sell – I was not sure that to do so I called John Foster and he came right over. He explained to me process and the Cumming Real Estate market and walked me through the entire process. This meeting alone increased my confidence. John Foster knows our real estate market – and helped me get my home sold when the prior agent could not. He listened to what my goals were and helped me get what I wanted. After his photographer took photos and I reviewed the listing – my feedback to him was “It looks perfect”. That is how I felt. I highly recommend John Foster as your Realtor. If you listed a home in Cumming GA and it did not sell – call John Foster and interview him to be your Realtor. You will be glad you did! K Wiliams Cumming Ga

John Foster is the best realtor in Cumming GA!! He is a hard working and helpful agent

I inherited a home when my Brother passed away. I was not sure what to do so I searched google and saw that John Foster is a Cumming GA Real estate agent that specializes in helping people that inherit homes sell them. He was very kind and understanding - it was very emotional selling my brother's home. John's marketing was excellent, his photos are beautiful and John was so helpful when explaining the Atlanta Real Estate Market, what to expect and how quickly the home would sell. If you inherit a home and want to sell it - I would highly recommend that you read John's book on how to sell inherited homes and interview John Foster to be your realtor. B. Gordon Cumming GA

John made selling easy!

John made selling easy!

My brother and I inherited a home from my parents, and the time came to sell it. My brother worked with John Foster as his realtor in Cumming Ga many years ago so he called John Foster and he was a great real estate agent to work with. He knew the contract really well and understood the process of selling an inherited home – I could tell he has done this many times before. John communicated with my brother and I throughout the process and I highly recommend him as your Real Estate agent if you have a home to sell in North Atlanta. If you have inherited a home and are considering selling it – you will want to talk to John Foster if you want to sell it.

John was very knowledgeable went above and beyond all expectations.

John was very professional. Kept us informed about the situation at least once a week. He assisted in having the house fixed by a handyman after the inspection before the closing. We definitely will refer his services to our friends. Very professional

We love John!

This was our 3rd time personally working with John. Our family has used his expertise 4 additional times. John is extremely patient and helpful. He doesn’t hesitate to let you know what he thinks or offer advice. He knows the market very well and is always there when you have questions. We truly couldn’t be happier that we chose to work with John again. We would definitely reach out to him in the future, if we ever decide to move again!

John was beyond incredible. He was very strait forward while also giving us our space to make decisions. He was a great teacher when it came to homes and buying a home in general, which was fantastic for us first time home buyers. His communication was very quick and efficient. He was careful to notice things that could’ve created problems down the line. His professionalism was met with great kindness and felt like a friend from the moment we met him. We are so very grateful for John!
