How much to save to buy a home: the complete guide
Buying a home is the largest financial decision most people make. Knowing exactly how much money you need before going to the bank — not just for the down payment but for all associated costs — is the first step to avoiding nasty surprises.
- You need at minimum 30–32% of the purchase price: 20% down payment + 10–12% closing costs
- Closing costs (transfer tax, notary, registry) are not financed by the bank — you need cash
- Transfer tax varies by region: between 6% (Madrid) and 11% (some regions)
- Monthly payment should not exceed 35–40% of your net monthly income
- Keep a buffer of at least 3–6 months of expenses after purchase
- Buying at the limit of your debt capacity is the most costly long-term mistake
- For savings with a 1–3 year horizon, use HYSA or short-term bond ETFs — not stock market ETFs
The 20% down payment isn't enough: the real amount you need
Banks typically finance up to 80% of the appraised value or purchase price (whichever is lower). This means you need at least 20% of the purchase price as a down payment. But that only covers the price itself — closing costs (taxes, notary, registry, appraisal) add another 8–12% on top. For a €200,000 property: down payment (20%): €40,000; closing costs (10–12%): €20,000–€24,000; recommended emergency reserve: €5,000–€10,000. Total needed: €65,000–€74,000 before signing.
What the closing costs actually are
For a resale property: Transfer Tax (ITP) varies by region — between 6% and 11% of the purchase price. Notary and registry fees: approximately €1,000–€2,000. Legal/administrative processing: €300–€600. Bank appraisal: €300–€600. For new construction: VAT at 10% (or 4% for social housing) instead of ITP, plus Stamp Duty (AJD) of 0.5–1.5% depending on the region (paid by the bank since 2018 in Spain).
Variables that affect how much you can borrow
The bank analyzes your debt capacity: the mortgage payment should not exceed 35–40% of your net monthly income. With a net salary of €2,000, maximum monthly payment = €700–€800. At a fixed rate of around 3–3.5%, a €160,000 mortgage over 30 years implies approximately €700–€750/month.
Worked example: €220,000 property
Purchase price: €220,000. Down payment (20%): €44,000. Estimated closing costs (8% transfer tax + notary + registry + processing + appraisal): ≈€22,000. Total savings needed: €66,000. Mortgage: €176,000 over 30 years. At 3.2% fixed, monthly payment ≈ €760. To qualify for that payment, the bank would require net income of at least €2,170–€2,450/month. With two applicants, the calculation uses combined income.
Common mistakes when planning a home purchase
Arriving at the bank without enough savings: some applicants confuse the 20% down payment with the total needed and run short of cash for closing costs. Banks don't finance those. Ignoring the emergency reserve: after buying, you should have at least 3–6 months of expenses in reserve for unexpected costs. Not accounting for mortgage costs: setup fees, potentially tied insurance, origination fee (rare today but possible). Buying at the absolute limit of debt capacity: an income drop or Euribor rise (for variable mortgages) can make the payment unaffordable.
How long does it actually take to save enough?
For a €200,000 property requiring €60,000 in savings (30% of purchase price): at a savings rate of €500/month, you'd need 120 months (10 years). At €1,000/month: 5 years. At €1,500/month: 3.3 years. But those numbers assume zero return on your savings. If you invest your savings at 4% annually: €500/month for 10 years grows to ~€73,000 (vs. €60,000 under the mattress) — reaching the target 18 months earlier. The takeaway: saving aggressively AND putting that money in a safe but productive vehicle (high-yield savings account, short-term bond ETF) meaningfully shortens the timeline. Rule of thumb: aim to save at least 25–30% of your net income during the accumulation phase. Track both how much you're saving and the return it's earning.
Where to keep your savings while building up
Your home-purchase savings have a specific time horizon (1–5 years), which limits how much risk you should take. Appropriate vehicles: high-yield savings accounts (HYSA) — currently 3–4.5% in the US, great for liquidity; money market funds — slightly higher yield, near-zero volatility; short-duration bond ETFs (e.g., iShares 1–3 Year Treasury Bond ETF — SHY) — low risk, better than cash. What to avoid: stock market ETFs for money you need within 2–3 years — a 30% market drop the year before you buy could delay your purchase by years. A practical framework: if your horizon is under 18 months, keep savings in HYSA or money market. 18 months–3 years: mix of money market + short bond ETFs. Over 3 years: you can add a small allocation to balanced ETFs (up to 20–30%), accepting modest volatility for better long-term return.
Frequently asked questions
How much do I need to save to buy a house?
In Europe, around 30% of the price: a 20% down payment plus 8–12% taxes and fees. In the US, the down payment can be lower, but closing costs add 2–5%.
Where should I keep my house savings?
In safe, liquid places such as high-yield savings accounts, deposits or money market funds. If you buy within a few years, not in stocks.
How long will it take to save?
Divide your target by your monthly savings. Lowering the target price or increasing savings shortens the timeline.
Should I use all my savings for the purchase?
No. Keep an emergency fund after closing for repairs, furniture and unexpected costs.
