Gadgets to attract millenial tenants

[Account Closed]

I'm under contract to purchase some smaller multi's in rapidly changing neighborhoods.   Next door to these properties on 1 side can be a 700k new build, and next door on the other side could be a boarding house.  Occasionally you may have the homeless guy zig zagging down the sidewalk pushing his shopping cart next to the lady jogging with her baby in a stroller.  I'm looking for ideas on how to attract and retain younger, quality tenants.  Has anyone done the nest thermostats or ring door bells in a rental?  Any good suggestions for good outside lighting?  Any other strategies or ideas we could include while rehabbing these units?  Thanks for the collaboration!
