That's like saying - a lease 'guarantees' that a long-term tenant will pay=-)It's no more nor no less guaranteed than in any other rental configuration...

With the current configuration, once you have clothes on one wall, there isn't much room to 'walk in' and get the ones at the back. 

This complex contains 12 units configured as a series of single-story brick duplexes and underwent extensive renovations in 2015.

When it comes to mid-term rentals, there's not just 1 "ideal" bedroom/bathroom count configuration! 

.,4 bath STVR duplex with identical 2500 sq ft configurations.

MTR in the winter months would be helpful, but as others have noted, it's not a great configuration for MTR. 

With cheap acreage properties with the right zoning, configuration and ground conditions, the cost to get started is cheaper than a dirt cheap house, you can add at least a couple of zeroes to the typical profit margins, most of the "work" is just paperwork for credit certifications to make them salable and, best of all, NO tenants.  

Seems liek a small lot --it depends on configuration --do you have access for second drive way --at least 20 feet wide --to go back for second home --just divide the lot or build as duplex --keep it Fee simple Not Condo --so you do not have to maintain --- check with some architect student at engineering college

I would be more concerned about the suitability of the unit given the configuration you described.

Play around with the configuration and see which is best.
