What is bridge financing and will I need it?

Bridge financing is a short-term loan that lets you close on a new home before the money from your current one arrives. It is common and routine on resale. On new construction it is more awkward, for a specific reason.

Why new construction complicates it

Lenders provide bridge financing against a firm sale: your existing home is sold, conditions waived, closing date fixed. They lend knowing exactly when they are repaid.

New construction breaks the symmetry. Your builder’s closing date is typically a tentative date the builder may extend, sometimes more than once and sometimes by months. How that works.

That means you cannot confidently sell your existing home for a date matched to the new one, because the new one may move. Sell too early and you need somewhere to live. Sell too late and you need bridge financing you may struggle to arrange.

The move-up buyer’s dilemma

This is the practical problem for most low-rise buyers, who are usually selling something:

• Sell early, firm, you have certainty on funds, but may need interim housing and two moves if the build slips.
• Sell late, near the builder’s date, you avoid interim housing, but you are selling under time pressure, which costs money, and you may need bridge financing.
• Sell conditional on the new closing, cleanest, but narrows your buyer pool and usually your price.

There is no free answer. The right one depends on your equity, your tolerance and how reliable the builder’s dates have historically been, which is a genuinely useful thing to know about a builder before you buy from them.

What lenders will want

• A firm, unconditional sale agreement on your existing home.
• Clear closing dates on both transactions.
• Confirmed mortgage approval on the new purchase.
• Equity sufficient to cover both positions.

Expect a higher interest rate than your mortgage plus an administration fee. On a short bridge the total cost is usually modest relative to the alternatives.

Planning it properly

Raise it early. Talk to your lender about bridging before you list, ideally a year out. Discovering your lender will not bridge a tentative builder date in the final month is a bad discovery.

Track the builder’s dates. As construction progresses the date firms up. There is usually a point, often after the pre-delivery inspection is scheduled, where selling becomes much safer.

Hold a contingency. Delays are normal. Budget for the possibility of a few months of carrying both, or of interim housing and storage.

Read the extension clause in your agreement so you know how far the date can legitimately move.

For a move-up buyer, sequencing the sale against a moving builder date is the hardest logistical part of the whole purchase, and the part where getting it wrong is most expensive. Let’s plan the sequence.
