Condition report, electrical report and hidden defects: how to see what is wrong with the house The condition report (tilstandsrapport) and the electrical installation report (elinstallationsrapport) show the house's defects, and together with an offer of change-of-ownership insurance (ejerskifteforsikring) they release the seller from the 10-year liability for hidden defects. Read the colour scale red/yellow/grey/black, the electrical report's icons and what the insurance actually covers, before you bid. What does it cost to own a home? Owner expenses, energy label and radon The real monthly cost of owning a home is more than the loan. Owner expenses (ejerudgifter) (land tax, property value tax, insurance, association), heating cost driven by the energy label (energimærke), and radon below 100 Bq/m³ decide what the home costs you every month. Here are the numbers. Registration duty and purchase costs 2026: what the deal costs on top of the price On top of the purchase price you typically pay 25,000-50,000+ kr in purchase costs. Registering the deed (skoede) costs 1.850 kr + 0,6 %, the mortgage charge (pant) 1.825 kr + 1,25 % (cut from 1,45 % as of 1 Jan 2026), and a property lawyer 4.450-10.000 kr. The estate agent is paid by the seller. Here is the whole calculation, so you know exactly what to have ready in the account before you bid. Can I afford it? Mortgage bond loans, down payment and debt-to-income ratio explained How to work out how much you can borrow for a home in Denmark: a mortgage bond loan (realkreditlån) up to 80 percent, at least a 5 percent down payment (udbetaling), a debt-to-income ratio (gældsfaktor) below 4, and an interest-rate stress test of plus 1 percentage point with a floor of 4 percent.
