About us

We help people who want to benefit from Knoxville's thriving rental real estate market—but who don't have the time or experience to find and manage the best investment opportunities. In today's environment, finding potential investment properties, analyzing their profitability, arranging financing, engaging in seller negotiations, and managing repairs or renovations can be incredibly time-consuming. By working with Martini Development on your next deal, you can gain a trusted partner with unique expertise in Knoxville's rental market.


At Martini Development, we're generous with our returns—we don't make money until our investors and partners make money. We understand that the most successful real estate investments require this win/win approach.

Our Past Projects and Recent Deals

Just a couple of our recent successes include:

  • North Hills Apartments

    Another 24-unit development in Knoxville is North Hills Apartments. Like Oak Hills, the area surrounding North Hills has experienced rapid growth of white-collar jobs, bringing both young professionals and families into the area. These units present cash-out refinance opportunities with a low vacancy rate.

    • Our Strategy

    When it comes to finding and vetting properties, we look for the following: 

    Investments that Cash Flow

    Value-Add Investments

    Stable Markets

    Highly Profitable Vacation Rentals

    Fix and Flip Homes

    Long-Term Rentals

    Our strategies are made simpler by our location in the fifth most recession-proof market in the country. Located within a day's drive for 60 percent of the country, Knoxville benefits from low unemployment, a low vacancy rate, a high concentration of business headquarters (including Regal Cinemas, the TVA, and Pilot/Flying J), and business- and landlord-friendly laws. Deals cash flow in Knoxville, and with Tennessee's increase in net migration over the last several years, the demand for rental housing is only set to rise. 


    Meanwhile, the Great Smoky Mountains area is a prime location for successful short-term rentals, boasting the most visited national park in the U.S. (with 12 million visitors a year), Dollywood, and other family-friendly attractions.  Vacation rentals in the Great Smoky Mountains have been around for more than 70 years, and short-term rentals are clearly here to stay.

    Investor Portal

    Easy Access to Your Investment Portfolio

    Our Investor Portal includes an easy-to-read Dashboard for a summary of all your investments. It’s designed to keep complex investment information simple and organized. 

    Understand Your Investments’ Assets

    Bring your investments to life with access to detailed information. Understanding asset details will give you a more tangible investment experience and will help you have more informed discussions with our team.

    Documents in One Secure Place

    Paper documents lack security, can get lost, and are difficult to safely share with CPAs and other financial managers. Important investment documents are organized and stored in the Investor Portal, which is backed by state-of-the-art data security.

    Real-Time Investment Performance

    It’s important to have real-time visibility to your investments’ progress. The Investor Portal gives 24/7 access to easy-to-understand performance metrics with both high-level data and details.
