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.  

I’d be happy to walk you through the process, from pre-approval to closing, and provide guidance on the best mortgage products for your goals.

For added liability protection, consider setting up an LLC for the rental, though this may have limited impact if the mortgage is in your name.This post does not create a CPA-Client relationship.

A classic example is Vestin Mortgage back about 15 - 20 years ago.

(I am starting investor, please understand)So many guys are buying in second-hand market, when original can not cover their mortgage payment because of the depreciating rent, and let go of their property at great value.

Summit county (Akron) has a much lower sales tax rate (6.75%) than Cleveland (Cuyahoga at 8%).The MLS in Akron shows homes at similar if not cheaper homes but for a good reason.

In this manual (which I assume could be modified to provide to tenants) I include all the financing information (which you would not include for tenants) bank accounts, mortgage accounts, payment information, and mortgage payoff), a list of the contractors, what each contractor does, a list of upcoming planned or necessary repairs, and a copy of all leases associated with the property.

It is what is left after snow removal, cutting the grass, utilities, tenant issues, parking lot issues, property taxes, mortgage payment, etc. that make a difference.

In both cases to keep things clean for underwriting at the bank I used my HELOC to secure the mortgage. 

This sounds complex, and if the conclusion you're coming to is mortgage fraud, I would not recommend it.
