Separate the purchase from the works
A property may look affordable until renovation, licences, professional fees and contingency are added. Build one sources-and-uses budget showing purchase price, taxes, transaction costs, works, technical fees and temporary accommodation.
Then identify which amounts must be paid at completion and which arise during construction.
The valuation may focus on current condition
A standard mortgage valuation reflects the property and accepted assumptions. Do not assume the lender will fund a future renovated value. Products that consider works may require a licensed project, fixed budget, contractor information and staged certification.
If the property is not currently habitable or has legal/planning issues, lender appetite can narrow further.
Prepare a real renovation budget
Obtain technical advice, scope, quotations, licence information and contingency. A cosmetic estimate is not enough for structural, energy or change-of-use work.
An independent lawyer and architect should verify title, planning, community restrictions and permits. Mortgage approval does not validate the proposed works.
Match cash flow to drawdowns
If funding is staged, contractors may need payment before lender release. Model certification time, VAT, overruns and the point at which the property can be occupied.
Compare financing routes
Options can include a standard purchase mortgage plus cash works, a purchase-and-renovation product, later refinancing or other secured finance. Compare total cost and risk rather than only the initial monthly payment.
RCG Finance can structure the funding case and identify viable lender routes. Send the price, works budget, property condition and available cash for an initial review.

Frequently asked questions
Will a standard Spanish mortgage finance renovation costs?
Not automatically. Some lenders assess specific purchase-and-works structures, while a standard loan may be based mainly on the current property and borrower.
