I decided to get a remote job, establish work history, save up enough capital for my first househack while I researched and learned about markets and strategies.I'd like to create an active business and I am looking at the MTR strategy.

The couple are both empty-nesters and each owns their own business. 

. #4 Once you're comfortable with everything and you find a deal you like, pull the trigger.

I market them as basically a 'turn key small business'. 

Doing so ensures they've had notice sooner rather than later, and also so they know I'm running a business and not simply enjoying a hobby in real estate.On the other hand, if the tenant doesn't pay the rent when due, the law in Michigan only requires a 3 day notice.

I knew a bulk deal would net something less.

And Grandma now gets to write off business trips to go see the grand kids every year.  

This would significantly help my ability to afford the market from a house hack standpoint, but I want to understand what those tax advantages are renting out my basement as a business rental.

If you will be doing future deals with your co-worker you might consider forming an LLC or partnership.

The only use case I know of for SBA-backed loans to finance real estate is when a non-RE business owner-occupies at least 51% of the property, such as an attorney firm buying the office building where their office is and leasing out the units they don't use.
