Fyrstu kaup

Buying your first home in Iceland? Start here.

Fyrstu kaup landing page — “Buying your first home? Start here” beside a line drawing of a house

Fyrstu kaup is a free, ad-free public-service site for first-time home buyers in Iceland. It turns the official sales registry into address-level valuations, an affordability map and a mortgage calculator that models Iceland's indexed and non-indexed loans, wrapped in plain-language guides.

01The problem

Everything a first-time buyer in Iceland needs is public, and none of it is usable. The sales registry, the affordability rules, the difference between an indexed and a non-indexed mortgage, the neighbourhood price data — all of it sits across banks, government portals and registries, in different formats, assuming you already know the vocabulary.

02The approach

The site treats the official registry as raw material rather than a destination. Recorded sales become an address-level valuation with visible comparables; income and savings become a map that colours neighbourhoods by what you can actually afford; the indexed-versus-non-indexed decision becomes a calculator that shows both curves side by side instead of a paragraph of explanation. Every data view names its source, every route is fully bilingual Icelandic and English, and there are no ads and no tracking anywhere — it links out freely to the banks and government services it sits alongside rather than competing with them.

03The outcome

A first-time buyer can go from "I have no idea what I can afford" to a specific address, a comparable sale and a monthly payment, without opening a bank's funnel.
