You could consider doing a cash out refinance of your current primary as an investment property with a dscr loan.From there get a low cost or zero down loan for your Primary.Use the proceeds left from the refinance to get your next property.There are so many different strategies.

@Robert Weissfeld, Yes, you can sell, cash out half, and 1031 exchange the other half. 

Consider the following: - renovation cost, monthly expenses, potential rental income, cash flow, return on investment6.

Given your expertise as a contractor, you might find an investor willing to fund the rehab in exchange for a profit share or interest on the loan.Cash-Out Refinance:If you own other investment properties, consider a cash-out refinance to pull equity from those properties to fund the rehab.I work for Aslan Home Lending and we have a HUGE variety of loan products, including the ones mentioned above.

One to continue my business out of, and the other to retain for cash flow.

You're stacking risk factors - long distance (I think), first time STR investor, short on cash, partner to buy the land, lack of financing options due to land and non-traditional structures, and a little distress/hurry.
