To make a more accurate estimate, you can use the Fotocasa mortgage calculator, which helps calculate both the required down payment and the estimated monthly instalment.
Monthly costs (mortgage + expenses)
In addition to the down payment, it’s essential to assess the monthly instalment you can comfortably afford.
The Bank of Spain (Banco de España) recommends that the mortgage payment should not exceed 30–35% of the household’s net monthly income. Exceeding this percentage may lead to financial difficulties in the medium and long term.
It’s also important to remember that the mortgage will not be the only monthly expense. Other regular costs include:
- Community fees
- Property Tax (IBI – Impuesto sobre Bienes Inmuebles)
- Utility bills (water, electricity, gas)
- Local council taxes and charges
- Possible special assessments (derrama) or home maintenance costs
2. Compare mortgages from different banks
Another key step before even deciding which property to buy is to research the financing options available. The mortgage market is highly competitive, and conditions can vary significantly from one lender to another.
Knowing in advance what type of mortgage you can secure allows you to search for properties within a realistic budget and avoid wasting time on homes that don’t fit your financial situation.
Some key aspects to analyse:
-
Interest rate: fixed, variable or mixed.
-
Arrangement fees or early repayment fees.
-
Linked products: check whether it is mandatory to take out products such as insurance policies or pension plans, which may end up increasing what we pay month by month.
-
Mortgage negotiation margin: since this is the first time we are buying a home, lenders will generally offer loans covering up to 80% of the property value. However, some profiles may be able to secure higher financing, and even mortgages covering 100% of the cost.
One important thing to keep in mind when buying a house is not to be influenced by the first offer you receive. Ideally, you should compare mortgages and request at least three proposals.
When comparing offers, consider not only the interest rate, but also fees, linked products and repayment flexibility.
3. Analyse what type of property you are looking for
Not all property features are equally important. If we don’t set priorities, we may end up buying something that doesn’t truly match our needs. We recommend dividing your list into three categories:
- Essential: minimum square metres, number of bedrooms, lift, parking space, etc.
- Desirable: balcony, storage room, south-facing orientation, green areas.
- Optional: features that can be added or improved later on.
A great help is using apps such as the Fotocasa app, which allow you to filter through hundreds of listings and find only the options that truly match what you’re looking for in your first purchase. You can also use the AI-assisted search to find your ideal home.
4. Find the best areas to buy a home
One of the main steps to buying a home for the first time without making mistakes is to carefully analyse which areas fit within your search. To do this, you should pay attention to at least the following highly valued aspects of a neighbourhood:
- Public transport and road access
- Nearby services: schools, health centres, supermarkets…
- Safety and street lighting
- Green spaces
- Leisure options
- Overall quality of life
