Adding mini splits worth it?

[Shawn Sopic]

I'm currently flipping an older brick single family home in central PA - 2700 sq ft, 4 BR 2.5 BA with ARV around $290,000 which is fairly high in my area. It currently has no cooling system (just ceiling fans). During this heat wave the temperature on 2nd floor has been in the upper 70s and even hit 80. I'm getting ready to list for sale within next couple weeks, but I'm afraid once we start showings, potential buyers may pass once they notice how hot it gets.

My question is, do I bite the bullet and add mini splits? Will I get return on my investment for something like that? Or should I just throw in a couple window units? I’d love to hear your opinions.

Thanks!
