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.  

If you have this debt and need money, you may not be preparing yourself for the challenges of being a landlord.

But you cannot exchange from an investment property into your primary residence. 

While you did point out the negative aspects of a deal like this, you didn't really highlight the pros on the RE side and future investment, appreciation etc.I’ve done two of these projects in the past 3 years in SoCal.

If I did, I'd find a place I really like to visit and be prepared to spend a lot of time there making connections.  

I'm considering tapping into the equity from either my primary residence or rental property to purchase another rental home that generates solid monthly cash flow.I'm open to investing out of state and have heard that areas like Ohio, Tennessee, Georgia, and North Carolina offer potential opportunities.

I was preapproved with that amount before, but it was for a single family, primary residence about six months ago.

Look at their rental history, the conditions of their previous residence, and ensure they have a good track record with past landlords.

If you do have to move because of a job, you would be safest (in my opinion, i am not giving legal advice or financial advice), i would sell that property to ensure that you did not just purchase with the goal of moving out early and taking advantage of lower rates and lower down payments for purchasing your home as a primary residence. 

It sounds like this is their personal residence.
