Bridge Loan Calculator
Buying before you sell carries a price per month. This tells you what it is.
What This Calculator Does
Prices the gap between buying your next home and selling your current one: the bridge amount your existing equity supports, the interest-only carry while both properties are held, the fees to originate and exit, and what every additional month on the market adds to the total.
Who Is This For
Move-up buyers in Miami and South Florida who cannot make a contingent offer stick in a competitive market, owners who found the right property before listing their own, and anyone weighing a bridge loan against selling first and renting.
How It Works
Enter your current home's value and remaining mortgage balance, the amount you need to bridge, the rate and fees you have been quoted, and how long you expect the sale to take. The calculator returns the monthly carry and the total cost across both your expected and your delayed timeline.
Frequently Asked Questions
What is a bridge loan?
Short-term financing secured against your current property that supplies the down payment for the next one before the first has sold. It is repaid when that sale closes, which is what makes the timeline the entire product.
Why is it interest-only?
Because it is never meant to amortise. The loan exists for a matter of months, so payments cover interest and the principal is retired in a single lump sum at the sale. That keeps the monthly carry manageable and concentrates all of the pressure on the payoff date.
What if my home does not sell on time?
That is the risk in one sentence. You keep carrying both properties, the bridge keeps accruing, and extension terms — where the lender grants them at all — usually arrive with fees. Model a sale that takes considerably longer than you expect and see whether the plan still stands.
Is a bridge loan expensive?
It is priced well above a conventional mortgage and typically carries origination and exit fees on top of the rate. With benchmark 30-year rates near 6.6-6.7% in mid-2026, bridge pricing sits meaningfully higher. You are buying speed and short duration, not a cheap loan.
What is the alternative?
Selling first and renting, or writing an offer contingent on your sale. Renting costs you a move and some inconvenience but removes the timeline risk entirely. A contingent offer costs nothing and competes poorly against clean bids in an active Miami market. The bridge buys certainty on the purchase and takes the risk on the sale.
How much can I borrow against my current home?
It depends on your equity after the existing mortgage and on the lender's ceiling against the property's value. Get an accurate payoff figure and a realistic valuation before you commit to a purchase, because the bridge cannot exceed what that equity supports.
