Whether that be setting up the team, finding the deals or the "boots on the ground" to bring the deal in.  

Set up a working line of credit.  

We (me and my fiancé) absolutely agree with you on that, and when we did our due diligence to set expectations for the rent, we were comparing our property to exactly what you said.

At the end of a set number of years I will pay you in full the remainder of the loan balance which we can track with the amortization calendar.

Hopefully, they were honest about those year 1 and year 2 numbers and set the expectation that your true numbers will hit in year 3 once you start getting repeat customers.You're sitting on 800k.

My property is set in a small neighborhood in a quiet lake town. 

Make sure to research local rates for cohosting and management services to stay competitive.If you're doing this as a side gig or part-time job, it’s essential to time block, create systems, set expectations with property owners, and establish boundaries to ensure a smooth experience for everyone involved.We opted not to pursue rental arbitrage for two key reasons: dealing with landlords and the significant upfront costs to set up and run a profitable STR without the benefit of property ownership.

Open a business checking account, obtain a DUNS number, and look into setting up accounts with companies that report to business credit agencies (e.g., net 30 vendor accounts).

when you buy a property you'll have a down payment, closing costs,  rent-ready costs, costs to get set up with a PM, a commission to place a tenant...

Not only do you have more flexibility, but you have another set of eyes on the deal, and you won't have to deal with the risk/huge changes to your personal credit.
