Given your situation, a property closer to Nashville might be more advantageous for short-term rentals like Airbnb, as proximity to a popular city typically attracts more guests and higher rental income.

Quote from @Jake Bute: Good Afternoon,I listened to Wheelwright's podcast the other day discussing how short term rentals do not have the same rules as long-term rentals when it comes to some of the tax laws around active/passive investing.

I own a small portfolio that brings enough income for me not to have a w-2 income.

May not be your cup of tea but they are cost efficient and they work to add passive income at a fraction of the cost to build a SFH.There are a few "Tiny Home" builders in Tampa and Manatee doing a ton of business.  

Previously I'd always used Stessa, which has a great Net Cash Flow statement view, breaking down the usual income/expenses, but also includes a section for Interest/Principal, and another section for CapEx. 

This could help decide if the income is enough.  

You can't sell your account.You can only sell SFR properties based on comps not rental income.

That question depends on if you have enough other income to qualify.

I've never heard of a lender that wouldn't count Section 8 payments as income.

It's a tough road though, not at all passive.
