We have also replaced two of the four heat/air conditioner units.

You'll be surprised how many appliances 2 to 3 years old are for sale I get my best deals in New York City when people leave their high-end apartments they tend to leave air conditioners in the windows the Super's get them and they have storage rooms filled with appliances that's where I get my best deals.

An air conditioner will eat 3 months of your rent.

There are several drain pipes that water funnels through in your air conditioner.

Notify the sellers and if the lease you are inheriting indeed says something to the effect of “2 installed working air conditioners” are the responsibility of the landlord then have them do that before closing. 

Home had new roof installed in 2017 and a new air conditioner 2014.

A poor man's air conditioner.

I've already had to replace several air conditioners, furnaces, hot water heaters and a roof, but I know several of my properties will need more big ticket items in the future and I want to make sure I'm prepared for it.  

I had a couple that got one and it managed to eat the plug off a window air conditioner, the quarter round in the bedroom and my front porch swing,   Also tore up the shrubbery in the raised bed in the front because, of course, the dirt was nice to dig into during the hot summer months.Since then, no puppies!

I've replaced the air conditioner (which was stolen while it was vacant), added 5 interior doors (that were missing for some reason), paid the property manager to paint the place at $2,250, replaced a few window panes, and bought a stove and refrigerator for it.
