Background: I am scaling up an Airbnb Vacation Property Management Business.

You're already in college, so it sounds like getting a degree is pretty probable so why not take advantage of a *higher* salary for a few years and the fact banks will find you more appealing and just use that to scale faster.

Great way to scale it up.

STR property management, Co-Hosting, Revenue Sharing agreements and Investor partnership agreements to earn equity and profit sharing opportunities as you continue to scale. 2.)

Like @Cory King said, house-hacking is likely the quickest way to scale. 

I’m going to need to ramp up on the Ohio market, find property manager, get a team together, look at ways of scaling with $50k.

A Pro membership gives you the tools and resources you need to start, scale or manage your portfolio.

I've created a VA POD so that I can easily scale from 1 to many with a pool of Top Gun VA's - call center, set appointments, cold call, project coordination, social media, SOP development,  etc. 

They become a part of your team in some ways and deal with all local contractors for you related to the propertyWhich one of the three above have you found to help you in your journey and how did you scale it from there?

In my area designers are in the $120 to $200/hr range so if it adds value do it for sure but on small scale projects I really don't think you will get that much impact especially for a vanilla basic house flip.
