How should I invest $300k cash in a commercial multi unit?

[Hyacinth Dolor]

I would like to get into the commercial multi-unit. I have $300k as deposit and about $200k in equity in my properties but not sure where to start besides mls and loop net. Currently, I have a few properties and try to keep a maximum of 4 properties due to me being owner operated, contractor and Realtor. I would like to remain site contractor due to my abilities and love the work more than the free time. I can put a team in place for electrical and plumbing. I will hire office manager and get my broker license to have site manager do my leases. The reason for this change is I see myself getting tied of running from one property to another shortly. I need input from Bigger Pockets. Help me find the correct avenue to start my goal of owning a high-rise within 12 months. I would like to stay away from partners and investor teams. 

Thank you for you advice.
