The post above reminded me that there is also a Facebook group called "Denver Area Mustachians" that you might want to check out.

I have them check it to make sure it isn't full of crap and check the propane.

Gotcha, thank you.Yes, we are actively speaking with our CPA to check on if this strategy would work for us!

We lost the equity piece of BRRRR, but we gained appreciation - something I did not see much in the earlier years.We work with the same contractors, we have standardized materials, we use the same vendors and SKUs for the most part - but still: if I am not on the job 3 times a week and check in on progress, quality and issues, things go sideways.Most of our OOS clients end up doing paint & carpet and will later say they are so glad they did not take on more!
