Would you put a portable AC in a rental?

[Hussain Harun]

I know there is a lot of threads about installing but none that talk in depth about portable A/C units...

Backstory: I purchased a 3 bed, 2 bath duplex in Baraboo, WI which rents for $995. Its about 1200 sq ft. It currently has a boiler with baseboard heating. No duct work currently. It seems like the majority of the rentals in my area come with some type of AC. In the past tenants have used window ACs but have resulted in significant water damage in the walls.

Question: I was considering alternatives to window ACs including: central AC, split mini ductless AC, through the wall ACs, or portable ACs (ones that look like dehumidifiers). Central and split mini ductless would run me at least $3900 per side from the quotes from installers. Through the wall is cheaper but an eye sore (for the neighborhood) and pain when looking for replacements.

So I"m wondering why nobody uses the little portable ACs? Particularly ones that is self evaporating so no pan to clean up under. I was thinking of buying them for tenants. Seems like a good investment to avoid costly water damage for poorly installed window ACs?
