Would it be wise to use a HELOC on our current residence to use for a down payment on a new propertyHi David, as someone who works with a lot of OOS investors, I would let you know that most of the clients I work with have never physically visited when buying their first investment property - the most important thing is working with a great investor agent and doing proper due diligence.

I'm very new to investing and weighing which options would benefit me the most.Option 1:  Use the cash as down payment on another primary residence and rent out the current.

I strongly advise you to get your primary residence taken care of FIRST.

But the manager's unit is really a 3000 sqft / 4 br / 2.5 ba SFR, and we live there as our primary residence. 

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.  

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.

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

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.

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.
