They can be installed just like air conditioners, and they function as A/C in the summer, and heat in the winter.

That means that even if you install a window air conditioner, as long as it's on the first level behind the fence, you're fine, but up on the side of the house on the second level will get you a letter.

If you are a newbie, you will not believe the conditions tenants will tolerate rather than getting prompt, proper, repairs done.I just re-rented a luxury home where the prior tenant never complained during a five year tenancy about anything, and due to very unusual circumstances a thorough interim inspection was never done:Range hood inopClothes dryer inopGarbage disposal inop5 of 7 exterior area lights inop; two interior circuits inop1 of 6 toilets inop3 of 5 air conditioners inoppool sweep inop5 sets exterior french door handsets so pitted you cut your hand opening the doorsrodent infestation in atticAll this in addition to nearly a complete repaint, stripping and resealing floors that had improper products applied, replacing 4 rooms of carpet, and minor miscellaneous items.Believe me, I would have MUCH preferred to make these repairs as they occurred, paying out of the cash flow, rather than having the owner fork over nearly 20K to make it rent ready again!
