After a long and complicated history with the current tenant, I’m now starting the eviction process.

While I don't have ideas on compelling Airbnb to do the right thing (unless you have national news reporter friends), what you've reported is one of my fears and you've had a great and successful history of bookings so far.

Several options you can explore to get the down payment capital: Solo401k; HELOC on personal residence or from equity of the SFR; Cash Value Life Insurance Policy; Business Credit; Private Lenders, to name a few.

Based on your numbers, and assuming you have a credit score high enough and have never filed for BK, you shouldn't have an issue getting approved for an HML to buy/rehab the property that I would estimate at about $370k-$375k (which includes 100% of the rehab costs).

And even tougher to get it financed.. from what I can see the only folks that build new are subsidized housing in some manner or  big tax credit plays something other than normal economics.

Quote from @Charles Fay: Hello all, first time posting and wanted to ask for your advice.currently in the military awaiting a 9-12 deployment within the next 6 months.I will have ~150k savings after deployment, 85k before, with no debt, payments or anything other than basic bills, 750+ credit.

My W2 income is very high (+$500k), excellent credit, but I hate my job and I want to leave within a year or two. 

While Johnson City might not have the pull of Pigeon Forge, it offers an authentic mountain experience that could attract hikers, history buffs, and visitors to nearby national parks.

That way, you might preserve some of your monthly profit while still knocking out that line of credit.

The credit unions tend to have lower fees and offer solid business products.
