If neighbor says they own it I would tell them I plan to construct a new one next to it on my property line even if I needed to lose a couple of feet of yard. 

These are all things I am trying to plan for. 

My point above is how solid are your financial and management plans?  

It may also make it easier for your estate planning attorney to line up ownership with your estate plan, assuming a CA-estate plan if a CA resident.

@Jeffrey Bourque Are you planning to finance this with a local bank or credit union?

You're better off opting for an interest-only mortgage, saving on payments, and then refinancing it into something more conventional when interest rates drop—or, if possible, making a plan to pay down the principal.Interest-only loans, which typically last for the first 5 to 10 years of the loan term, offer two key benefits.

I would be thinking about future loans as I plan to do purchase another property soon after.
