Really looking to upgrade to battery powered access control to be more efficient and cut costs during turnovers.

Electronics ones would be fine hard wired, but batteries don’t last very long in 60° with wind chill very long is what I meant

When i arrived she handed me a bill for $200 for batteries that had been replaced in the chair. 

You have no idea what is under there or how they treated the top cap.Who would want to have a garden on top of lead and old batteries?

You'll have less drama and be able to enjoy living together as friends.How to charge rent?

Plan on adding a 100kw DC charger, around 50k-100k after rebates. 

Regardless, batteries and back covers seem to go missing constantly whatever the remote brand. 

Right, the list of things to maintain and/or replace is never ending; rugs, AC filters, light bulbs, water filter in fridge, detector batteries, pest control, coffee maker, stove eyes and pans, silverware, bowls, glasses, sofa cushions, pillows, blinds, brooms, mops, vacuum, brushes, shower curtains, bath mats, beach towels. 

For that reason I think it's more critical for you than others to do whatever you can to stand out (ex: EV charger, arcade games, amazing photos, allowing dogs, etc.).
