They usually sell for a really attractive price because investment property financing is (obviously) difficult, somewhat limiting the buyer pool to owner-operator small business owners (who in turn are typically great clients, as well).  

@Nadia Jones Starting and running a fund is a separate business because it's something that you need to actively market for and regularly work on attracting capital to invest in. 

Understanding your market, what you are offering, and the kind of tenant you can expect to attract and KEEP will help you determine how to screen.

The ability to use leverage to acquire more attractive assets and amplify their potential gains4.

As I am new to this and looking for cashflow using rentals, one key aspect of this investment is to ensure that the unit rents out quickly and while I do understand that cash flow to begin with might not be attractive, it can be a good investment in the long run if the location is right(as appreciation also kicks in).

Any way to capitalize on this garage outside of just attracting higher rents once I move out and/or higher sales price if I decide to sell?

 @Jake Baker Love that strategy by being to attract tenants with affordability and getting the stable monthly cash flow compared to weekly rentals which may have a higher profit but a much higher risk making them not really viable in today's market. 

Determine the price that attracts the investor, stop the bleeding and and move on.

Not a ton of value-add opportunity, more of a core+ investment in a very small market I'm familiar with - my initial analysis is yielding a 14% IRR & 1.28 EM, so I'm not sure of the attractiveness to investors.

It’s crucial to have local market knowledge or work with someone who does.
