Case study
Sanne and Tom had been living in their own apartment in Amsterdam for six years when they signed for a new-build home in Almere.
The completion date was eighteen months away. The part that worried them was the middle. Their apartment wouldn't sell until the new house was ready, which meant carrying two mortgage payments at the same time — plus the staged payments to the builder as construction progressed. On paper the new mortgage was affordable. What they couldn't work out was whether they could survive the overlap without running their savings dry. They also weren't sure whether to sell first and rent for a year, or hold on and risk the market moving against them.
1. Mapped the full timeline Toni set out every payment month by month, from signing to handover: the instalments to the builder, the interest on the construction deposit, and the point at which both mortgages would run at once.
2. Calculated the real overlap cost The construction deposit earns interest that offsets part of the payments, and they'd only pay interest on the portion drawn down so far. The actual overlap was far smaller than they'd assumed.
3. Arranged a bridging loan This released equity from the apartment before it sold, so the overlap was covered without touching their savings.
4. Chose the sale timing deliberately With the numbers clear, they decided to sell close to completion rather than a year early — avoiding a year of rent and a second move.
5. Fixed the rate at the right moment Toni compared lenders on how long they'd hold a rate offer, which matters more on new-build than on an existing home given the long lead time.
