Ah, yeah if your plan is to use potential cashout money for a vehicle, perhaps a HELOC isn't ideal, as it is "borrowing" money from a property's equity. You're still paying for it. In a HELOC, most lenders will lend on 75-80% of a property's appraised value, minus a potental mortgage balance. In my case, I have a duplex that was appraised at $167,000 at the time. The lender lent on 80% of that value, or $133,600. Minus the mortgage balance of about $98,000 at the time. So, the amount of credit they lent was about $35,000. My interest rate is whatever the prime rate is, plus 1%.
In my opinion, HELOCs are ideally used in a BRRRR type situation, in which, you're using the money for a short period of time, then you're selling or refinancing out and pulling it all back out. The goal, at least my goal, is to continually recycle that HELOC money, not leave it in any property, since I am paying for it. Going back to your plans, yeah, I wouldn't use it on a vehicle purchase. Cashed out funds would probably be better suited for that. However, if using HELOC money on improving your other properties increases their value enough to refinance them and pull that money back out, maybe it's feasible in that situation.
