In the future, we are probably going to look for cheaper alternatives for flooring and cabinets.

But even the hint of an alternate use in the units (hair salon downstairs) suddenly classifies this as more expensive 'commercial' loan. 

@Kevin Dougherty  I am trying to find an alternative to SFRs.

Given the choice, buying a duplex (assuming you mean both sides) is a better option for a few reasons. 

I would try to find a way to do some sort of desk and TV in each room so that they have the choice to work in their room or work in a communal space.

Alternatively, i have looked in the midwest states and it seems there are many properties that have positive cash flow potential.

Evidence would be a lease in the tenant's name, a current utility bill in their name at another address, and/or a copy of a current bank statement with their alternative address on it. 

But that was more by necessity than choice.

The alternative is to have the title under a business partner, either a friend or family member, to keep things legal (mortgage will likely be under my name).Worst case I stay at the Marriott and keep the MFH as a pure rental but that extra $2900/month going towards the property during the months I’m TDY would be nice.I’ll discuss with my local Finance office as well but just wanted to see if anyone has had similar experiences. 

Rather, such plans are simply a mean to diversify with broader investment choices.
