Bridge Loan Calculator
Owning two properties at once has a price per month. This attaches a number to it.
What This Calculator Does
The gap between buying your next home and selling your current one is priced out in full: the bridge amount your existing equity supports, the interest-only carry while both properties are held, the fees to originate and exit, and what each additional month on the market adds to the total.
Who Is This For
Designed for move-up buyers across 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
Supply your current home's value and remaining mortgage balance, the amount you need to bridge, 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
How does a bridge loan work?
It is short-term financing secured against your current property that supplies 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 the loan is never intended to amortise. It exists for a matter of months, so payments cover interest while the principal is retired in a single lump sum at the sale. That keeps the monthly carry manageable and concentrates every bit of pressure on the payoff date.
And if the sale takes longer than planned?
That is the risk stated in one sentence. You continue carrying both properties, the bridge continues accruing, and extension terms — where the lender offers them at all — usually arrive attached to fees. Model a sale that takes considerably longer than you expect and see whether the plan holds.
How expensive is bridge financing?
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. What you are buying is speed and short duration, not a cheap loan.
What else could I do instead?
Sell first and rent, or write an offer contingent on your sale. Renting costs you a move and some inconvenience while removing the timeline risk entirely. A contingent offer costs nothing and competes poorly against clean bids in an active Miami market. The bridge purchases certainty on the purchase and takes the risk on the sale.
How much will my equity support?
That depends on your equity 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 supports.
