Personal and Family considerations to although that to happen ..

Hey Roberto - I personally would only pull the down payment from the HELOC just to lessen the risk associated with leveraging your personal home.

I personally prefer staying in a nicer STR and appreciate nicer finishes, details, and a unified ascetic, and want to provide a similar experience to our future guests.  

Many companies are offering STR coverage.I will also say don't listing to a single person who tells you AirBNB and VRBO 1m dollar guarantee is insurance.

Personal guarantee? 

I supply toilet paper, paper towels, liquid hand soap at all sinks, dishdetergent, dishwasher pods, one new dishwashing sponge, spray oil, salt & pepper (I buy the plastic disposable ones for picnics so they can't be refilled) and a few other spices, trash bags, some cleaning supplies such as Simple Green and microfiber cloths, coffee filters, plastic wrap, ziploc baggies, laundry detergent, and dryer sheets.Guests are asked to bring their own shampoo, conditioner, personal soap for showers, sugar, creamer and coffee. 

Network (virtually & in-person)3. 

We have a core 4 in TN area and a personal connection to both areas.

But generally yes, I personally have seen people (just spoke to one today) that took over a property doing 40k with a PM and going to 83k.

If not, it is what it is and if you personally want to move to Texas than so be it and you may need to sell it.Now, if you can keep the first one and still afford a second one then great.
