Renovation loan: mortgage or unsecured credit

You can finance a renovation with a purpose mortgage, a non-purpose mortgage secured by property or an unsecured personal loan. The right option depends on the budget, available security, desired term and the documents you can provide. A lower monthly payment does not by itself mean a lower total cost.

Compare three options

Option	Security and use	What to compare
Purpose mortgage	Legal charge over property; funds are for renovation	Budget, permits, invoices or photos, drawdowns, valuation and fees
Non-purpose mortgage	Legal charge; use usually does not need to be documented	Potentially lower LTV, rate, fees and the risk of pledging your home
Personal loan	No property security	Shorter term, higher payment, APR and total amount payable

For a mortgage, the bank decides whether to release funds at once or in stages. It may ask for an itemised budget, a building permit or notification, current and future valuations, photographs or receipts. Requirements can differ within a bank depending on the loan type.

Illustrative payments for the same amount

A €20,000 loan over 20 years at a model rate of 4% has an estimated annuity payment of about €121.20 a month. A €20,000 loan over 8 years at a model rate of 8% is about €282.73 a month. These are mathematical scenarios with a constant rate, excluding fees, insurance and bank assessment. The rates are not current offers from specific products.

The lower payment in the first scenario mainly reflects the longer term. Before choosing, compare total interest, fees and the balance after the same number of years. Enter your amount and rate in the mortgage calculator.

What differs between banks

For construction and building alterations, Fio banka publishes a minimum loan amount and requires a budget plus valuations of the current and future property. VÚB describes a budget, photographs and a declaration instead of invoices for its own-build process. Slovenská sporiteľňa describes staged drawdowns and conditions under which it does not require purpose documents. ČSOB allows additional renovation funds with a declaration under a specific refinancing offer; this is not a general limit for every mortgage.

Do not treat these bank examples as identical products. Before signing, get written confirmation of the drawdown deadline, documents for each tranche, fees and how completed work must be accounted for.

Grants and your own funds

Loan terms are not a promise of a grant. A bank notice or a link to a home-renovation programme does not establish that a call is open, that you qualify or that costs will be reimbursed. Check the current call with its administrator and plan your financing so you can cover the work if a grant is delayed or refused.
