The only issue is the interest rate is 7.125%.

A line of credit is adjustable rate with interest only payments that will have a "draw" period usually of 3-5 years for investment properties (usually 10 years for primary home) then will amortize over the remaining term after the draw period.

Don't expect rates to come down.
