Arizona Landlord: Is it a good idea to buy stuff from Mexico?

[Ximing Feng]

Hi guys,

Hope this finds you well! 

We are trying to put mini-splits in our tenant's bedrooms. My family told me that we can purchase the mini-splits from Mexico and bring them back to the US, which can save us a couple of hundred dollars. Given that we visit my family in Mexico sometimes so the transportation is not of a big concern, do you see any issues with it? What about buying maintenance material in general from Mexico? 

Thank you very much!
