Thanks for update! I'll have to go at least 24k unless the price isn't much different. Did you do a double mini split? It going well during these summer months?
Thanks for all the useful information. I'm getting ready to build mine also. But quick question. Did you have to get permits right away for water and electricity when you started your slab? I wanted to future proof and get the pipe in now, but will likely wait a year to get it all installed.
