Have you considered this option as well? 

but you would only want to do this as part of a BRRRR, otherwise you're paying closing costs twice for no reason, as well as the interest on the HELOC prior to refinancing. 

For me as well as the seller.First, you have to define Sub to financing.Do you mean the reckless kind where you overpay for a property, take over the financing and borrow from others to cover closing costs and holding costs when you have no money, no credit, no income, no reserves and can't tell a warranty deed from a deed of trust and you close on the kitchen counteror do you meanbuying below market value, already having a nice income, having reserves, using escrow and title, already understanding the due on sale clause, have done a lot of creative purchases and know when to use and when not to use creative finance and how to recover if something goes amiss?

Then when we’ve done our first or second property, we could get into flipping homes as well.

If interested in adding another state / city to the list I am happy to connect - but hopefully this is irrelevant and you are already progressing along well with your purchase!!!!  

You might even want to setup a C-Corp (for tax and liability reasons as well) to manage the business with the guests and pay rent to your LLC. 

Report breaking and entering - as well the occupation. 

Sometimes paying a premium on a home also guarantees a higher demand in the neighborhood and with that may come a higher demand for a rental as well.  

My situation currently is I have 1 SFH rental that is owned by my LLC and doing well, and also I'm doing a live-in flip on my primary residence.

They all use the same Real Estate Agent as well and she is a shark.
