I strongly recommend Harold Hartmann to anyone who is looking to buy or sell a home in Orange County.

In 2008, we needed to relocate from Seattle to southern Orange County on a compressed schedule, due to a job transfer. We started searching online, and chose to contact Harold because we preferred his website’s ease-of-use and the information that it provided.

We flew down to California and had one three-day weekend to look at homes. We were very pleased with the selections that Harold had chosen to show us. He had understood our requests exactly. He also had an excellent process for guiding us through the process of selecting a new home.

We finished up paperwork remotely, from Seattle, and bought the condo that we are still enjoying today. We were very fortunate to find an agent who is so good at what he does.

I have known Harold for 14 years. He's managed 3 home purchases for me, both for my primary home and investment properties. He's very professional, friendly, gives good advice and spends the time necessary to allow his client to make a good decision. I would go with Harold again if I were purchasing another home.

My wife Debbie and I recommend Harold Hartmann to anyone looking to buy or sell a house. Our experience with Harold has been nothing short of amazing.

We first met Harold in 1987. We lived in Long Beach and did not know the local Orange County market. Fortunately, we met Harold and he helped us find our dream house in Mission Viejo. Later, he found the perfect home for Debbie's mom, and recently the sell of a rental property in Rancho Santa Margarita.

Not only a superb agent, but he was a trusted advisor who understood our needs and goals as he guided us skillfully throughout the entire process.

Buying and selling property can be a stressful endeavor. We were thankful Harold has been there to provide support and confidence that things will, and did, work out.

I've known Harold for about 25 years now. He helped me and my family find our first home in 1989 and then helped us find our next home many years later. Harold took the time to understand what we were looking for and worked diligently to make the deal on our second home work out. He pays attention to detail and is always available to answer questions. Harold has been a big help over the years even in matters not related to the process of selling or finding us a new home. Matters such as home maintenance issues, and helping us lower our property taxes by providing the necessary information for me to submit to the county tax office. More recently I tried refinancing my home loan for a lower interest rate but the value the appraiser placed on my home came in too low and the loan was denied. I called Harold and he was able to provide more accurate information than the appraiser had, and my lender was able to use that information to get the appraiser to amend the value of my home. As a result, my loan was approved, and my monthly payment was reduced, thanks to Harold. Harold has had my trust and I'd recommend him anytime."


Loan Officer at United American Mortgage Corporation

I have known Harold for over 30 years. We met, working for the same real estate company. Harold was always one of realtors that associates went to with a difficult business situation. His knowlege far exceeded most of the other realtors.

I eventually left real estate and became a Mortgage professional. Harold and I continued to work together. He referred his buyer's to me to handle their financing. His clients were always satisfied with his expertise. I work with many realtors, and he exemplifies the word "professional".

Greg Hamer

Hydrogeologist at amec E&E

I first met Harold more than 25 years ago when looking for a home in Lake Forest. He was efficient, thorough, and very knowledgeable about the area we were interested in for a home. He even wrote letters to homes in the neighborhood we were interested in, asking if owners were interested in selling. I really like that he shows initiative. I made several referrals to Harold, which resulted in satisfied buyers.
I give Harold a strong recommendation, and would not hesitate to use his real estate services in the future.

Harold is a true professional and trusted colleague. When I referred my brother to Harold as a businessman relocating his family from California to Florida, I knew Harold had his work cut out for him! I am happy to report that my most particular brother raved about the awesome job Harold did in selling the home in a challenging market. Kudos to Harold, Realtor(R) Extraordinaire!
