This person likely has a 30-year fixed rate mortage financed at less than 4.5%. 

It is going to be near impossible to cash flow on a property with 100% financing, especially if that partners rates are above conventional rates.

I've done a couple of direct loans, but for the most part, I work with a mortgage broker who brings deals to me.

Every where you turn there are STRs going up on the market fully furnished because they couldn't pay the mortgage and bills with the rental income.

Quote from @Ryan Mcpherson: Moved to Austin for work and purchased a home in 2021 with just under 4% interest rate.

To me personally as well I found it was more important for what I do to cultivate commerical bankers and those relationships so I could get access to bank rate capital and lots of it !!

Through the LLC structure it is possible to take advantage of the existing mortgages modified first at 4,125% 22yers and 1%, yes one percent, for 40 years.

However, the rental value this area is very low compared to the Home values and mortgage rate.

Keep in mind if you buy another primary residence, you'd have better rates, terms and can pay as little as 5% down for multi family up to 4 units.
