Unit B has newer forced air furnace, Unit A has an old gravity style furnace, still functional.

@Jeri HerreraThe only tax benefit I can think of that you get on commercial property that you wouldn't on residential property is Section 179 expensing categories that allows you to 100% expense roofs; heating, ventilation, and air conditioning property; fire protection and alarm systems; and security systems.

Also the basement is an air bnb. 

Thanks for your help,Jordan Applegate

If you allow pets, ensure your outside air conditioner condenser(s) are fenced to keep from the pets peeing onto them.

Hey @Brent Salazar -- I would second @Jordan Jones's suggestion. 

@Marty SummersI don't see any problem with it if they are paying the bill and as long as the air conditioner is connected to the electric outlet with the correct amperage able to handle the load.

My last Air-B&B was great.

Who needs to turn up the air when you leave when it's free?!  

I researched our area using Air DNA and it seems like the asset would do well assuming we can keep it booked at a decent rate.
