Each city has is own ordinances from code and violations enforcement to yes Airbnb (short-term rental or not).Then you need the best management company is the blood of you business.

I am considering opening a business account at JP Morgan for all income + expenses, and simply use baselane for rent collection + higher APR on security deposits, etc.

I run a kitchen design and supply business.

My wife and I are based in Florida and work as non-profit business consultants.

Traditional DSCR (Debt Service Coverage Ratio) loans typically consider the entire property's rental income, not individual rooms.

I'd want the business to be inherited by my family.

I own 1 profitable rental property and I am retired, keep separate records on my rental property.According to IRS guidance it states:  "If an interest in real estate fails to satisfy all the requirements of the safe harbor, it may still be treated as a trade or business for purposes of the section 199A deduction if it otherwise meets the definition of a trade or business in the section 199A regulations."

If you are buying rental properties and you can qualify for conventional lending, Fannie and Freddie will require the properties to be in your individual name. 

What you need to do is get a property and some experience managing it to see if this is the right business for you.I would not wait until graduation.

Which in turn will bring plenty of other investors and general business to the market.
