Who cares about lifetime interest costs, except to the extent you can easily lower them (refinance to a lower interest rate) to increase your cashflow.

Id go right into looking at local credit unions and small community banks for HELOCs (lines of credit) so you can have a lower blended rate and draw/payback as you please.For the 3F - Since this is free and clear, you would only be looking at 1st position options here in the world of financing.

If you’re looking for short-term cash flow, you might need to explore nearby markets with lower entry costs and higher cash-on-cash returns, even if they aren’t as familiar to you.

HELOC: A cash-out refinance could be more beneficial if you're looking for a lump sum to purchase the new property outright, particularly because interest rates may be lower than a HELOC.

I think it was Airbnb that had suggestions for me to lower my pricing because they were scanning the competition (Booking.com in that scenario) and saw a lower price.
