The unit is also not a pure investment; I plan on moving  back into it eventually.

You could also get the perfect tenant who really takes care of your house.From a purely business perspective.

Its purely for entertainment like others have said.

So, my question is- would yall make the down payment pure HELOC?

Seems almost everyone from purely an investment position shifts parks this way. 

I also use Turbo Tax and had no problem with it.Just pure speculation here, but I get the sense that what they don't want are people claiming QBI benefits for things like Triple Net Leases (i.e., where the tenant, as opposed to you, your agent or your contractors is responsible for conducting most lease related activities).

Thinking otherwise is pure madness.

@Michael PlaksThe scales have fallen from my eyes and I have been enlightened with the ray of pure and perfect knowledge that you have chosen to shine upon me in my benighted ignorance.

Are you looking to do something similar with your investment or are you purely buying the property for investment purposes?

So pure graphs not reality in REI I think
