A 18,000 btu mini split I installed can perform a minimum of 5,400 BTU's.
I'm not saying install a 18k system where a 6K is needed, but installing a 18k system where you need 12K will not cause you to have high humidity.
2) 700sq feet per ton should not be used for everyone. Region and building design determine cooling and heading load. Parts of Michigan with great insulation may only need 1 ton per 1,000 sq ft. An area of Texas with bad insulation may need 1 ton per 300- 350 sq feet.
3) You must also factor in heating performance in your region and unit specifications. A 12,000 BTU cooling unit may get 16,000 BTU of heat at 47F, however it may drop to 8,000 BTU at 5F.
18K = $1,299.99
24K = $1,499.99

That's typically true, but these are high efficiency units that have variable speed compressors. They can run at lower speeds instead of constantly triggering on and off.
12k=12000=1ton
The only reasons to oversize(in a normal residence):
Is in Arizona(or similar) heat and lots of opening closing/poorly insulated.
If using these as heating units more than cooling.

I have a 1500sq ft cabin with 22 ft tall ceiling and too many old windows. I was going to spend $8k this year on half the windows and still have a problem heating and cooling the place. This 24k should put a huge dent in that need.

"Pre-charged w/ eco-friendly R410 refrigerant"
I have a 750sq ft garage with a split 70/30 of 14' and 12' ceilings (all walls and garage doors are insulated). I am just north of Denver and would like the best unit for heating (maintain 50°F throughout the winter) and cooling (maintain 70°F while I am working in there, otherwise 80°F). Had I not read all the previous threads about being careful not to oversize, I would have sprung for the 24k without a doubt - but now I have my doubts. The 24k has a higher BTU rating at lower temperatures, which I figured would be beneficial for my needs.
For the record, I tried a 18k BTU window unit in my service door and built a frame to hold the unit. Unfortunately, even starting it at 5am at full blast it was only able to take 4-6°F off of the ambient temperature when the temperature was 95+ outside.
Thanks.

I installed a Senville unit that wasnt not a DIY unit myself this past spring. It came pre flared and deburred. I would say I only have average DIY experience although probably more electric experience than most.
