I think a lot of people like using the platform since even the primitive sites offer more space and privacy than a 'typical' public campground where you can hear the next guy snoring.   

When you're responsible for customizing the layout you can get more creative and find extra space a builder missed out on because they wanted to include some type of flex space or amenity room or it just didn't fit their box.

A pro tip is if you call shared office spaces or co working spaces in your city they also offer virtual mailbox services at usually better prices than the national ones!

If they see that youre generating cash for operations via a non-RE business activity, it could be an issue.

Is it in a Revocable trust or non-revocable? 

It works like this:(1) Save up enough money for a down payment(2) Buy a single family home that you will Airbnb/VRBO(3) Ensure the “average period of customer use” is <=7 days(4) Materially participate (5) Cost segregate the property, resulting in large depreciation deductions(6) Use the losses from step 5 to offset your W2 incomeWhat makes this possible is that operating an STR is considered “non-passive.”

Testing and tweaking over time helps us dial into the best strategies for each unique market.It’s helpful to hear what’s working well for others in the space!

In-unit washer/dryer is always a plus people are willing to pay more for, but even it's just on site and not necessarily in their unit it will perform better than a space with no access to laundry. 

Their support is non-existent.

I provide washers and dryers in second-floor apartments or when the space requires a stacked unit.
