Typical cosmetic (lifestyle) upgrades we do are better/more LED lighting, dimmers, flooring, paint, trim, solid wood door slabs in place of the hollow core etc.

we have 3 properties. but the best benefits to me are the message templates and automatic messaging and door coding, along with being able to handle direct bookings.

I've not done that remotely, but it could be done.I have a handyman that gets used appliances all the time and installs them in my rental houses when needed.It would take some trust or coordination on your part but could save you some substantial money.I'm sure you could find someone on the next door app that was handy and had a truck to go pickup stuff.

@Ashish Acharya Thank you so much for your feedback, I completely agree and have included seasonal trends and will look into economic factors including rental demand drivers.

I currently have 4 doors here in Columbus, Ohio and I'm looking to add some more rentals to my portfolio.

I'm looking to replace the front door of my rental property.

IE change your drivers license to reflect both addresses and pay the bills on both to make it like both are your primary residence? 

All 4 properties could be up to 4 units and you could be looking at as many as 16 "doors" in 4 years if you were to live in each home for only 12 months each. 

Willing to help out with ground work or if you need me to cold call people or door knock.

Either recommend tenants sign up for it and get the $5 "kick back" from those that do or offer it as a service for the entire community and increase the rent to compensate.
