It’s a higher down than a conventional non commercial loan   They look at your FICO BUT not your income.  

When I asked him why wouldn’t they just stay at MGM like a normal person, he said there’s this group of people who prefer the privacy of a non-commercial property lease.

I explored the idea of forming an LLC, but we would both like to obtain a non-commercial loan to take advantage of lower down payments.

I am seeing non-commercial DSCR loans as low as 3.750% right now and closing in 20-25 days.  

BP is a good place to brainstorm, but you should always have the deep conversation with your professional.Although it is cheaper to refi outside an LLC with a non-commercial mortgage, you'll want to talk to your professional about the impact this will have on LLC members who aren't on the mortgage, as they might not get debt-basis if only one member is on the loan.

Meanwhile, the relatively scarce individually-owned units are still priced relative to non-commercial RE market forces, including, among a variety of other factors, a lack of traditional financing options for the individual units (because of the predominant non-owner-occupied / single-corporate-owner circumstances within the complex). 

Would owning CRE or non-commercial RE using a trust or LLC be beneficial to my situation knowing I want to get a good rate as much as I can for the primary home mortgage?

Income potential does not have role in the value of non-commercial residential roperties (less than 5 units).  

Even if it didn't fit perfectly the bank will go to 80% on noncommercial loans so if the appraisal came in higher than purchase and rehab it was still less down.
