Renovation finance: the project cost is not the lender’s added value
Separate essential repairs, energy improvements, valuation and phased cash needs.
Define the project before financing
A renovation budget should distinguish essential repairs, energy improvements and discretionary upgrades. Each category has a different urgency and may be treated differently in valuation and financing. Obtain specifications and comparable quotations before asking how much more can be borrowed. A vague lump sum for “modernisation” leaves the lender and household guessing. Include professional fees, contingency and temporary living costs where relevant. The borrowing decision should follow a defined project rather than encourage expanding work simply because credit might be available.
Cost does not guarantee value
Money spent on a renovation does not automatically increase the lender’s accepted value by the same amount. Ask how the property is assessed before and after work and which evidence supports the improvement. Decorative choices may have substantial personal value without adding equivalent lending value. Financing based on completion can create a temporary cash requirement during construction. Clarify drawdown conditions and inspection dates instead of assuming the entire facility is paid before the first contractor invoice arrives.
Hypothetical funding gap
Imagine CHF 80,000 of work and a lender willing to finance CHF 50,000 under its assessment. The household needs CHF 30,000 plus a contingency, not merely the initial contractor deposit. If half the work is payable before the loan drawdown, timing adds another challenge. These invented figures are not lending criteria. They demonstrate why cost, approved credit and invoice calendar must be shown separately and why a project can be affordable in total yet short of cash midway.
Recalculate the permanent budget
Adding debt changes interest and possibly amortisation beyond the construction phase. Update the household’s affordability and retirement scenarios on the total debt. Expected energy savings should be labelled estimates, with their source and uncertainty; they are not guaranteed income for loan approval. Retain a repair reserve after the project and do not use the same cash as both equity and contingency. A renovation that improves comfort but removes all resilience can leave the household vulnerable to the next ordinary interruption.
Check ownership and permissions
For shared or condominium ownership, identify who approves the work, who owes the invoice and whether common-property arrangements apply. Obtain the necessary permissions before making the financing unconditional. Ask professionals about contracts, staged acceptance and warranties. Insurance during the works is another distinct question: home contents cover is not automatically a complete construction policy. Describe occupancy and the nature of work to the relevant insurer, and request written confirmation of any changes needed during the renovation period.
Close with a funded contingency
Your final file should contain scope, quotations, approved loan, drawdown conditions, invoice dates and a funded contingency. Set a point at which overruns trigger reassessment rather than another automatic borrowing request. After completion, reconcile actual expenses and update property and insurance records. FINMA’s mortgage-risk guidance supports careful valuation and sustainable borrowing, but your lender decides the individual case. A strong renovation plan remains workable when costs or timing deviate modestly from the first optimistic budget.
