Bridge loan mortgage: how to buy your next home before selling the current one

The problem is classic: you find the home you want but your money is locked in the one you own. Sell first and you need somewhere to live while searching. Buy first and you need capital you do not yet have. A bridge loan solves this timing gap — it finances the purchase of the new property before you have sold the old one, giving you a grace period to organise the sale without pressure.

  • Bridge loan = one mortgage combining the current home's debt + financing for the new one during the transition
  • Bridge period of 1–2 years: you pay interest only until you sell the current property
  • Once sold, proceeds cancel the portion of the loan tied to the old home
  • Not all lenders offer this product — a mortgage broker can identify which ones do
  • The lender requires solvency to cover the full amortising payment from day one, not just the reduced rate
  • Alternatives: sell first and rent / simultaneous completion / cash-out refinance

How a bridge loan works

A bridge loan combines two financial obligations into a single temporary mortgage: the outstanding debt on your current property and the financing for the new one. During a transition period (typically 1–2 years) you pay reduced instalments — often interest only. Once you sell the old property, that portion is cancelled and the remaining loan covers only the new home.

Step by step:
1. Both properties are appraised
2. The lender grants a single mortgage covering: outstanding balance on the current home + purchase price of the new one
3. Bridge period: you pay reduced instalments (interest only or partial capital repayment)
4. You sell the current property → proceeds cancel that portion of the debt
5. Remaining loan = standard mortgage on your new home only

Real numbers: what a bridge loan looks like

Practical example:

  • Current home: appraised at €200,000, outstanding mortgage €40,000
  • New home: purchase price €250,000
  • Lender finances: up to 80% of new home (€200,000) + cancels €40,000 outstanding balance
  • Total bridge loan: €240,000

During the bridge period (until you sell the current home):
• Interest-only payment at 3.5%: ≈€700/month
• Full amortising payment: ≈€1,200/month

Once you sell for €200,000:
• Cancel the €40,000 outstanding balance
• Decide how much of the remaining €160,000 to apply to the principal
• If applied in full: remaining mortgage ≈€40,000 with minimal monthly payment

The lender requires from day one that your income can cover the full amortising payment (€1,200) — not just the reduced one — in case the sale is delayed.

Lender conditions and limitations

Not all lenders offer bridge loans — each institution decides whether to include this product. Typical conditions:

  • Bridge period: 6 months to 2 years depending on the lender
  • Maximum LTV: lender limits total exposure to 80–85% of the combined value of both properties
  • Interest rate: usually slightly higher than a standard mortgage (0.1–0.3% additional spread)
  • Income requirement: earnings must cover the full amortising payment from day one
  • The lender may require you to prove the current property is actively listed for sale with an estate agent

Not all lenders offer this product. A mortgage broker can quickly identify which ones do and compare grace period terms.

Alternatives to a bridge loan

Sell first, rent while you search. The most conservative option. Sell, receive the proceeds, rent temporarily, and buy without time pressure. Downsides: two moves, rental cost, and the market may rise while you wait.

Simultaneous completion. You coordinate the sale of your current home and the purchase of the new one on the same day. Proceeds from the sale fund the purchase directly. Requires perfect timing — difficult but possible.

Cash-out refinance. If your current property has significant equity and a small outstanding loan, it may be more efficient to release capital through a cash-out refinance and use that cash as a down payment on the new property — without needing a bridge loan.

Short-term personal loan. Only viable when the sale timeline is very short and the bridge amount needed is small (maximum €20,000–30,000).

When a bridge loan makes sense — and when it does not

It makes sense when:
• Your current property is in a high-demand area and will sell within 12 months
• You want to avoid two moves and a temporary rental period
• You have found the right property and cannot afford to wait
• Your income comfortably covers the full amortising payment if the sale is delayed

It does not make sense when:
• Your current property is hard to sell (low-liquidity area, high asking price, poor condition)
• Your income margin is tight — a delayed sale could leave you unable to cover both obligations
• You are buying under pressure — with a bridge loan active there is a strong temptation to overpay for the new property to avoid losing it
• You do not have a cash buffer of at least 6 months of the full combined payment

Frequently asked questions

Usually from a few months to about two years, while you sell the first property.

Selling first and renting temporarily, a sale with a delayed move-out, or using savings for the down payment.
