A purchase bridge is a short-term loan to buy a property when the long-term money cannot be ready in time, or the property cannot yet qualify for it. That covers a chain that has broken, an auction or off-market deadline, a property that is not yet mortgageable, and land bought ahead of planning. It lends against the property as it stands today, and is repaid by a sale, a refinance, or development finance once the plan is in place.
Land bought ahead of planning is the case development finance cannot cover, because it needs full consent, a defined scheme and a costed build before it will lend. A purchase bridge lends against the land as land instead, typically 65 to 70% of its open market value, on a term set around the planning programme rather than a build one.
The other reason to bridge a purchase is speed. Two to six weeks is typical on a clean deal, with a complete pack, the legal work ready, a motivated client and good solicitors, which is what wins an off-market deal or holds a chain together. The risk to respect is the exit: the usual way a purchase bridge goes wrong is planning arriving later than the term assumed.
The exit is the underwrite
A purchase bridge is priced on how it gets repaid, not on the property. Development finance, a term facility or a sale are all credible exits, but only if the route is established before you draw rather than after.
Land valued as land
Without consent the security is the open market value of the site, not the scheme you intend to build on it. Expect around 65 to 70% of that, and expect a valuer to be conservative about hope value.
A term set around the planning programme, with headroom
Nine to fifteen months is typical, matched to the determination timetable. We build in room for the committee date that slips, because that is the common case rather than the unlucky one, and an extension negotiated late is an expensive extension.
The refinance lined up behind it
The strongest position is a development lender already circling before the bridge completes. Then consent triggers a refinance that is underway rather than a fresh search with a redemption date approaching.
