If you had borrowed the 10K for your SUV and had a payment of 185/month assuming 4.25% interest rate, you could have easily made that one payment with the 10 grand you had sitting in the bank. heck, you'd have that payment for next 55 months...So you might have a little higher insurance that would push it down to maybe 48 months. Plus, if you really want to talk worst case scenario and self protectionism, if things really got bad, you could let the SUV go back and have 10K to feed yourself.
I think in our hard lessons learned from being hurt by debt or seeing others hurt by debt, we have skewed our logic so far to the other side as to not see a situation for its actual risks and rewards. I agree that people make this kind of decision as 90% personal, but I don't agree that this is correct logic.
Finally, if you are okay with an unsecured note to make a DP on a property such that you have 100% financing on the property that will have low cash flow to break even for the first 5 years but cash flow like crazy after the unsecured note is paid off, most astute investors would do that and work on maybe paying that note back quicker. To me, a car note with a great term is no worse than an unsecured note with a great term. So many people willing to jump on hard money lenders for loans, yet the same ones (many of them) would balk at car note. It makes no logical sense.
