Thank you all for your input and different perspectives.

From a mortgage perspective, does anyone have a definition of what "Primary Residence" is and how it is tested? 

From a tax perspective, keep in mind state tax exposure.

The cost to file a tax return for a corporation is much higher than it is to complete a personal tax return as well, so you should probably confirm this with your accountant.From a legal perspective it makes sense to have a corporation, and your lawyer will almost always advise you do so. 

Agree with your advocations but from a legal perspective, I'd be truly shocked if this charge stuck. 

@Josh AndersonJosh thanks for putting the numbers in perspective, it really helps out being able to determine cap rate and overall purchase price.

I guess it depends on the person's perspective, but for the most part I would think all could be written off versus depreciated.

I get the appeal of BRRRR for those who lack cash or want to scale faster, but to me it seems like I am introducing unnecessary variable/interest expense in taking out some kind of high interest LOC (sofi offered unsecured $100k at 9% or my bank will do secured $50k at 7%).Interested in any perspective, thank you. 

Here is a graphical diagram to help you on some of these questions and quest: So, another perspective would be to apply the "Asspro rule of 2%" (© Costin 2018) - the cost of setting up and maintaining your asset protection should be less than 2% of equity you are trying to protect.

Is this an appropriate adjustment of perspective as costs shift or am I just being too aggressive as I search for more deals?
