Thank you Mark Krantz / Broker & CEO of Keys to the Lake for overseeing my group of condos, Osage National. You were there when I really needed someone to step in and take the reigns for me. I live in Kansas City. My husband died in 2009. Mark and his team worked hard to get the units leased out on a full time basis for me. They maintained and made repairs as necessary and maintained the property.

They were a blessing to me. I enjoyed my relationship with Keys to the Lake and I would recommend them to anyone who could use their services. I sold the group of condo in 2012. Thanks again, Keys to the Lake.

Lake of the Ozarks Vacation Rental Testimonial

Our family has owned a condo at Lake of the Ozarks for almost a decade. It was purchased for occasional use by our family, but mostly as an investment. The plan was to rent it out ourselves and save the expense of the management company. That didn’t work (at all). We researched management companies and thought we found the best choice. It was a long and less than profitable relationship. There were a number of reasons we left, not just bookings.


Keys to the Lake came highly recommended by several people. After only one season we are wondering why we didn’t look harder 10 years ago. Not only have the number of bookings increased dramatically, but the level of service is incredible. They have continually provided answers to all of our questions, and worked with us through some complicated issues. Keys to the Lake is a well organized, respected, and professional company, which is hard to find these days. Be assured that Keys to the Lake is the only company we will use for management our condo.

Mr. & Mrs. J.

Palisades Owner

To Whom It May Concern:
I have been the president of three office building associations: The Palisades Centre, The Brandon Michael Building and the Crossings for several years now.

We have used Mark Krantz/Keys to the Lake to manage all of these properties.  Both the maintenance and financial aspects have been second to none.  Mark and his organization have proven to be extremely personable, efficient and well qualified to handle this type of operation.
I would wholeheartedly recommend them to anyone looking for a management company.
Please do not hesitate to contact me for any further information regarding Mark Krantz and Keys to the Lake.

To Whom It May Concern:
I am writing this letter in regards to the Keys to the Lake Management.  I have a condo at the Harbor Point condominium complex, and am currently the president of the association.  I have been a board member for over four years now.
In June 2006, we entered into a contract with Mark Krantz from the Keys to the Lake, to manage our condo complex.  Their duties are to maintain the complex, keep a check on all portions of the buildings, grounds, docks, etc.  Also they manage all collections, payments, and all the book work.  It has been a pleasure working with the Key’s entire team.
Since the Keys have taken over, it has been a much easier and more rewarding position for all of the board members.  All our ledgers and reports are done in a timely fashion, and are easy to understand.  When something needs to be addressed, one phone call is made, and you know it will be taken care of.  Their work is done effectively, and in a very professional manner.
I feel our decision to work with the Keys to the Lake as our management team, was a good one.  I highly recommend the Keys to the Lake to other associations. Thank You!

Leroy Klauser

President, Harbor Point Condo

To Whom It May Concern:
Keys to the Lake was hired by Cedar Heights Condo Association to manage the existing 180+ unit project.  The transition was as smooth as could be and the management has been easy to work with.  In the first 6 months they did a very good job, have done what they said they would do, and have a been a pleasure to work with.  Employees have been as good as we expected and very workable.
I would recommend Keys to the Lake for any complex of this type from my past experience.

Board of Directors, Cedar Heights Condo Association

To whom It May Concern:
My name is Dave Fleming and I’ve the vice president of the Timberlake Master Association Board.  I’m writing to introduce you to and tell you of our experience with Keys to the Lake as our Property Management representative and Mark Krantz and his employees.

Some background, we had a property management team in place for several years and after many problems and disappointments we asked for other management companies to give us bids.  I wasn’t on the board at the time, but after hearing from the current board and their recommendations, I voted to give Keys to the Lake a chance.

This past year has been a learning experience for all of us, the board and Keys to the Lake.  They have stood by and supported us through our issues with our sewer treatment facility, water issues, pool problems and many other items that we had no idea were going to become so complex and consume so much time.  Not once did Keys to the Lake or their employees ever say that things couldn’t get done!  In my opinion, they went above and beyond what I felt was their responsibility to help us through many tough issues.  Mark, Sherri, Dave, Shane, and Laurie have provided our complex with excellent service.  They really care about what happens daily!

We have recently asked Keys to the Lake to submit a bid to stay as our property manager for the next three years.  We have been very pleased with their service, response to our needs, and a genuine concern that things will be done right!  I own other condos around the lake, Keys to the Lake stands head and shoulders above other companies.  If chosen to be your property management representative, I’m sure that you won’t’ be disappointed!

I wanted to commend you and your staff on the professionalism Keys to the Lake displays as a Management Company. As a Real Estate Appraiser I am in and out of most all of the Lake Area’s Condominium Developments throughout the year. The developments you manage are always clean, I am able to access the units in a timely manner, your on site staff is knowledgeable of the development’s amenities, dues and special assessments. Cedar Heights is one of the developments I work in most often and also one of the larger developments at the Lake. I am impressed at how clean and well maintained the grounds are every time I’m there. As always I appreciate Keys to the Lake’s assistance.

Mark, just wanted to write and tell you how much I appreciate Keys to the Lake. It is so good knowing that even if I am out of town for an extended period of time that Keys will be there to answer any questions a tenant may have and make sure that any physical problems that may arise with the unit will be resolved immediately. Also, your office staff are outstanding. I think of the times that I have called in a state of near panic because of an issue with a unit that I really did not understand and I probably did not do well trying to explain what was wrong. Your staff person was patient, listened, and attempted to find a resolution to the problem. (Amazing they didn’t even laugh!)

Anyway, thanks for all that Keys does for me.

As owners of a condominium rental property, our experience with Keys to the Lake has been nothing short of outstanding. Our rentals have been strong and have increased every year. The Keys staff is pleasant, professional and quick to respond to any question or need we have. Our condo is in great shape when we are there for personal stays, which speaks to the quality of renters that Keys attracts, as well as their cleaning staff. We highly recommend Keys to the Lake as the property management company for any condominium rental property owner.

Mr. W

Emerald Bay Owner

As chairman of the Budget Committee from August of 2008 to August of 2011 when I became President of the Cedar Heights Board of Directors, I have had the pleasure of working with Keys To The Lake Property Management personnel. With 182 sold units in our complex, Cedar Heights is more like a small community than a condo complex. With diverse ownership comes challenges and Keys To The Lake has dealt with them in a very professional and positive manner since the beginning of their management of Cedar Heights in January of 2008. With the purchase of the developer rights and the remaining property in March of 2014, Keys To The Lake employees, especially Mark and Stephen Krantz, were exceptional advisors to the Board during the over a year long process.

As a professional engineer, I really appreciate their TEAM approach; the professional, positive, and progressive manners of all employees; and would highly recommend them for any size complex management, big or small, to help fellow board members deal with the challenges that WILL occur from time to time.

Michael L. Davis, PE

President, Cedar Heights Condo Association

I have been involved in the development of seven condo projects in the Lake of the Ozarks area over the last 20 years. I can honestly say I’ve never found a management company any easier to deal with than Keys to the Lake. Every KTTL team member with whom I have had the pleasure of dealing has returned my communications promptly with a “can-do” attitude. Katie is very knowledgeable and is especially good at networking with area businesses and doing research when special conditions arise. If you have condominium management questions, Mark Krantz and his team can get you answers.

Keys to the Lake did a great job managing our condo and subdivision homeowner associations. They instituted a very efficient and organized system. Their office staff and onsite personnel did an excellent job. We would highly recommend Keys to the Lake.

I want to thank you again for you and your company’s good work with the management of our projects. You now have three of my projects and you have done a great job of managing them and keeping the relationship between owners and developers on an even keel. That is a difficult challenge to say the least, and you’ve done very well indeed.

Timberlake Village is made up of 112 occupied condos, 15 buildings, 39 residential lots and/or homes, 13 multi-slip docks, 5 pools, several acres of common ground, and is led by 3 separate associations with 9 total board members.  In 2008, when our boards became owner occupied, we felt it was our duty to begin an exhaustive search for the absolute best management company to manage our property and provide superior service to our owners at a fair price.  A great deal of time (over 12 months) was spent reviewing bids, interviewing potential companies, and performing random inspections of properties managed.  In 2009, we informed our ownership, and current developers, that we were making a management company change for 2010.  I can assure you this was not a casual decision.

KTTL took over management responsibilities for Timberlake Village on Jan 1, 2010.  Mark Krantz and his team have not only met our expectations, but far exceeded them.  The quality of service clearly starts at the top with KTTL.  I know Mark visits our complex weekly, something that stood out during our company interviews.  There is a sense of comfort knowing that Mark stands behind the work of his employees and takes the time to visit the properties he represents.  Sherri, our property manager, has made herself extremely accessible and is eager to make certain our owners are happy with KTTL.  Sherri is very responsive to our board members, and quite frankly gets the job done on all levels.  I can’t say enough good things about the grounds team assigned to our property.  Our pools are the cleanest they have ever been, the grounds look fantastic, and our owners absolutely love Dave and Shane. Laurie in accounting is fantastic and was very helpful during our transition.  Every request we’ve made of Laurie has been met with a “can-do” attitude.

When we made the decision to change management companies for 2010, each of our 3 boards signed a 1-year contract to see if KTTL was a good fit.  I can tell you that all 3 of our boards now collectively agree that we absolutely made the right decision with KTTL and it is our desire to enter into a long term relationship with Mark Krantz and his team.  I think that speaks volumes.

I am happy to discuss with any potential client how satisfied we are with KTTL, and would encourage them to visit Timberlake Village.  I am proud of our complex, and I am confident that we have the best lake management company in KTTL handling our property.
