What is the specific product you used, if you don't mind me asking?

And yes, the income from renting is still taxable, but ideally you are offsetting a chunk of that with depreciation which is a non-cash expense.You should read Amanda Han and Matt MacFarland's books as well which are available in the BP Bookstore. https://store.biggerpockets.com/products/tax-strategies-book...

Would a low enough sales price make all of my concerns go away?

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.  

For walls in common areas like halls and stairs, there are rigid products that can absorb some sound.

These loan products include a partial release feature that allows them to be repaid gradually as TIC interests are sold, and ensure that the sold TIC units are not encumbered by a blanket encumbrance.- The variety of financing products available as individual tenant in common loans remains limited, and the terms are generally less favorable than either apartment building loans or condominium loans.

Steadily has their own product (with multiple writing companies) and then they offer policies through other carriers just as an independent agency would. 

Rates that low don't make sense especially if they're a no doc shop.

The owner occupant rate is super low compared to many states but as a rental it goes up alot.
