That being said, it's just a white noise/humming sound, just like having a window air conditioner.

I was talking to my property manager in SW Florida one day and they told me they had a tenant that refused to use the air conditioner.

I would think that the rental income would be enough, but we were hit with a couple big bills for roof and air conditioner replacements over the past few years, so the numbers weren't impressive enough for the banks. 

It had been vandalized, all the appliances were gone, the two central air conditioners were gone, some of the blinds, all of the shower heads. 

Depreciation can be applied not only to the property but also to fixtures, such as air conditioners, so if those fixtures are also new, the tax savings can be even greater.On the other hand, used property does not provide the same tax savings as new property because many years have passed since it was built, so it's useful life may be less, or in some cases, almost zero.

., hotel/motel shampoo, soap, conditioner, snacks, etc supplier?  

Current plans include: new patio, solar panels eventually, moving the pool filter/pump from the corner of the yard to the side of the house near the air conditioner to free up space. 

Depending on the age of the one you purchased air conditioner condensers refrigerators and tuckpointing seem to be the biggest expenses

Do you agree if this is a typical price to replace a furnace and an ac for a 3B/2B 1400 sq ft home (Gas Furnace, Up to 96% efficient, Up to 60000 BTUh and Air Conditioner, 2 Tons, Up to 18.00 SEER, 71 dB max)? 

I’m planning on installing an electric furnace/air conditioner in both units.
