The fresh air, no traffic and no one in the gym expect for the one or two regulars.

Thought about a leaking air conditioner and laminate?  

At that time, I'll be moving into one unit and renting the other.The duplex is in an upscale neighborhood in Los Angeles where units like this (3 beds, 2 baths, private yard, private 2-car garage, central heat and air) rent for $5000+ and comparably sized houses rent for $6500+.

I am looking into managing Air Bnb properties and would like some advice on how to get started.

My central air crapped out in my own house 2 nights ago, it's 15 years old. 

Timelines for the leasing is a bit up in the air.

In my case, I also stock portable air conditioning units in case of a prolonged AC outage.  

As a HVAC & plumbing tech, I'll tell you first hand that Tennant's rarely are on top of changing air filters regularly.

I am going by the pictures, and things that have happened to me before.From the photos:The central air may be not working at all or not working well - you can see the outside unit at the back of the house, but there are window or portable air conditioners in two of the bedrooms and the living room.
