and the entire conventional wisdom of the 70% are there any people who don't really use it all and have found out their ways of making the numbers work Like adjusting the percentage based on the market. 

Webinars about the project can bring people to see what you are offering.

Technically, Conventional allows 15% down but you end up incurring a hefty hit to your rate/points options when you put down less than 20%, which makes causes most people opt to put 20% down.

Held for 8 years and make a small amount.

Oh and people would fill out buyer or seller forms, and they would never populate.

Obviously do your own research before asking people on Facebook, but just another way to connect with hosts and see what they do and how they file those STR taxes and maybe some additional helpful info. 

@Landon Sheveland People do fix and flips while living into the property to classify the property as primary residence and not pay any capital gain taxes. if that is your intention, don't use LLC to establish this as your LLC.If your goal is different compared to what I said above, you can use LLC.

What I see a lot of people do is overthink it and then either stop in their tracks, or wait for years to get started due to the overwhelming data that they get on what they want to do.

But I will say that 1031 will not apply, that needs to be a longer-term hold/investment. 1031 applies to rentals, STRs, MTRs that are held for much longer. 

If I did need to, Zillow would be my next go-to as I'm seeing more and more people use it.
