Woah 13.85% even on an investment property is super high...I got a heloc at a 7.25% (this is variable with the market as with any HELOC) for an investment property.Talk to your local credit union.

Hopefully we will be managing a handful of other STRs in the same market in the future.

Or you could decide that you're going to hang in there for family/legacy reasons, and keep raising the rent whenever the market supports... and whenever you turn over a set of tenants.

I tried attending one in my local market a couple of times but felt like I was in some hotel ballroom being pitched on how the 12 year-old kid up in front would teach us all how to run to the back of the room to swipe $10K on our AMEX for the secrets of real estate investing.

If looking to change the market value of property, well there you go. 

I avoid the multi-family market here, so unfortunately, I will not be a good go-to here, but I am confident you will find quality resources and help here on BP.  

Any brokerage can be the right fit for you so long as you commit to taking initiative and putting in the work.By 'work', I mean income-producing activities (lead generation and follow-up) i.e. cold calling, door-knocking, contacting your sphere of influence, networking, hosting open houses, running online advertising, marketing (paper or online), or anything else that will get you in front of prospective clients.My first broker rarely answered my phone calls and by the time she responded, I'd often already have the answer I was looking for.

You won't find one PM that hits all 3 markets as there is a pretty decent distance between the 3.

I won't be out-marketing anyone. 

@Ella Marie, I can't speak on behalf of your market, but in my respective market, competition is tough, and the successful fix-and-flip vendors are often full-time operating businesses.
