I'm working on first STR purchase. Considering cash down payment versus HELOC draw for the down payment. Why I'd use cash is to avoid the HELOC payback (fixed 7.1%, 10/10, not yet tapped) and increased cash flow (no HELOC interest repayment) for the STR. On the other hand if I used the HELOC for down payment I preserve cash for to scale in near future and for rainy-day funds. Any suggestions?
