This isn’t/wasn’t a loophole - just tax policy. 

You’ll pay more for tax prep, more for record keeping, more for financing but what will you get?

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.  

The only taxes I remit directly now are the tiny town tax they implemented of 1%.I just take my net income spreadsheet and calculate the 1% and give them a check.

At a 7% annual return, this could grow to $908K after 10 years, providing immediate liquidity and diversification.Alternatively, holding the property could yield $825K net equity after taxes in 10 years, assuming a $900K sale, with the potential to defer taxes via a 1031 exchange if reinvested into another property.

Hey @Nick Gallon Martin, I recommend speaking to a Tax Planner/CPA, @Jeff Nash would be a great resource for you.

Could VRBO users from Michigan provide some clarity about the topic of sales tax/lodging tax collection and payment to the state.

Somebody bought that house at Tax Sale.   

Whether you need a CPA with just three rentals depends on the complexity of your situation and your comfort level with DIY tax prep.If things are pretty straightforward, you might be fine with tax software for now.

I don't know the answers on taxes, but New Jersey is the densest state in America.
