Fridge upgrade or no? Stainless steel $1800 fridge for $800?

[Lydia Fogo]

Hello! Right now my partner and I are house hacking a duplex that we hope to move out of and start renting in a year. The duplex is in a solid B neighborhood in Chattanooga, TN and we're hoping to get ~$1000-$1150 a month. It has a backyard, a garage, new bamboo floors, and is a 2 bd 1.5 BA. 

Our decision is this: we'd like to purchase a fridge so that we have two for ourselves. If we're going to take it with us in a year, we'll happily buy a cheap $200 used one off of Craigslist. OR, we could buy a $800 stainless steel French door fridge from our local used appliance store that is discounted from $1,800 and leave it in the rental unit when we move out in hopes of it upping the rent/attracting tenants.  It works great and looks amazing. I guess my question is: is it worth it to pay $600 more for a fridge that is significantly better then the one we have for a rental? Can you actually up the rent because of the fridge/ does it really make a difference to the tenants? If we could charge $25 more a month, the fridge would pay for itself in 2 years... our current fridge is a little typical white two door cheap fridge. 

Thanks for your input!!
