Looking for various tax strategies to reduce the reality that a large RV or boat is a grossly depreciating assetI would not have a loan, so claiming it as a primary or secondary residence and claiming the mortgage deduction is not applicable.I sold my primary residence and I have several rental properties which I use as I'm fixing them up.What I'm pondering is living aboard and working aboard developing a new product, while traveling.  

Housing is one of those things that people like to scream about, but the reality is that there are more than enough places for everyone to live.

It is just a reality how many PMs have no idea how to process claims and have close to 0 systems to protect assets for business owners. 

You're tricking your brain into thinking that you're taking action when, in reality, you're not.
