Bridge Loan Calculator
Buying before you sell has a price, and it is charged by the month. Here is yours.
What This Calculator Does
Puts a number on the gap between buying the next home and selling the current one: the bridge your existing equity supports, the interest-only carry while both properties are held, the fees to originate and to exit, and what each additional month on the market adds to the bill.
Who Is This For
Anyone trading up in Miami and South Florida where a contingent offer simply will not stick, owners who found the right property before listing their own, and buyers weighing a bridge loan against selling first and renting.
How It Works
Enter your current home's value and remaining mortgage balance, the amount to be bridged, the rate and fees 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 does a bridge loan actually do?
Short-term financing secured against your current property that provides the down payment for the next one before the first has sold. Repayment comes when that sale closes, which is what makes the timeline the entire product.
Why are the payments interest-only?
Because it was never meant to amortise. The loan lives for a handful of months, so payments cover interest and the principal is retired in a single lump at the sale. That keeps the monthly carry manageable and puts all the pressure on the payoff date.
What if my home sells late?
That is the risk, stated plainly. You carry both properties, the bridge keeps accruing, and extension terms — where a lender grants them at all — normally arrive with fees. Model a sale that takes considerably longer than planned and see whether the arrangement still holds.
How expensive is bridge financing?
It is priced well above a conventional mortgage and usually 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. What you are buying is speed and short duration, not a cheap loan.
What else could I do instead?
Selling first and renting, or writing an offer contingent on your sale. Renting costs a move and some inconvenience but eliminates timeline risk outright. A contingent offer costs nothing and competes badly against clean bids in an active Miami market. The bridge buys certainty on the purchase and accepts the risk on the sale.
How much will my equity support?
It depends on the equity remaining after the existing mortgage and on the lender's ceiling against the property's value. Obtain an accurate payoff figure and a realistic valuation before committing to a purchase, because the bridge cannot exceed what that equity carries.
