Investment-Property HELOC Calculator
A rental-property HELOC carries two penalties a primary-residence line doesn't: a lower borrowing cap and a higher rate. This shows the haircut, then pressure-tests it the way a lender does — on the fully-amortizing repayment payment and the property's DSCR, today and under rate stress — not the cheap interest-only draw.
How is the property occupied?
Does the rental survive the line?
measured on the repayment payment, not the interest-only draw — the number a lender qualifies you on
The haircut: what the rental costs you vs. your primary home
the cheap, temporary phase — the teaser
fully amortizing — what you qualify on
the jump when the draw period ends
rent after vacancy + operating costs (never gross)
existing P&I + the repayment payment
the interest-only teaser — flatters the real number
lenders generally want this under 43%
Reserves — the buffer that carries a vacancy or a rate jump

DSCR and cash flow are on the repayment payment, re-amortized at each rate — not a linear bump.
