How to figure out the maximum home price you can afford
Before you start browsing listings, you need to know your real ceiling. The maximum home price you can finance depends on three combined factors: your monthly income, the savings you have available, and current interest rates. Ignore any one of them and the budget stops being realistic, which ends either in disappointment or in borrowing too much.
- You need 28–32% of the price in savings: 20% down payment plus 8–12% in closing costs
- Bank finances up to 80% of appraised value (not necessarily the purchase price)
- Aim for 28–30% of net income on the mortgage payment, not the bank's 35–40% ceiling
- Interest rates dramatically affect how much house the same monthly payment buys
- Always keep a 3–6 month emergency reserve after buying
- Bank approval maximum ≠ what you should borrow
The 4–5× annual salary rule of thumb
A widely used quick guide: the maximum home price should not exceed 4× your gross annual salary (up to 5× when interest rates are low). With a gross salary of €35,000/year, the reasonable range would be €140,000–€175,000. It is only a starting point: your real ceiling depends on your savings and the debts you already pay. Use it to quickly filter realistic markets and neighborhoods before running the full numbers.
The savings you actually need (most people underestimate this)
European banks typically finance up to 80% of the appraised value, meaning you need at least 20% as a down payment. But that's only part of the cash requirement. Closing costs add another 8–12% of the purchase price: notary and registry fees, transfer taxes (6–11% depending on the region and the type of property) and the appraisal. In total, plan to need 28–32% of the purchase price in available savings before signing. The bank does not finance these costs.
The real constraint: the monthly payment you can sustainably afford
The price you can afford is not only what the bank allows. It is what you can pay every month without strain. Banks apply a hard limit of 35–40% debt-to-income (DTI): at €2,000 net/month income, maximum accepted payment is €700–€800. But the financially prudent recommendation is to keep the mortgage payment at 28–30% of net income, leaving margin for other costs and emergencies. Use that threshold as your real starting point, not the bank's maximum.
Full worked example: two scenarios
Net income €2,200/month, savings €40,000, no other debts. Scenario A (prudent, 30%): max monthly payment €660. At 30 years, 3.5% fixed → loan ≈€147,000 → max price ≈€184,000. Savings cover 20% down (€36,800) + closing costs (≈€18,400) with a small buffer remaining. Scenario B (bank maximum, 35%): max payment €770 → loan ≈€170,000 → max price ≈€212,500. Savings barely cover the down payment with nothing left for closing costs or emergencies. Scenario A is the safer path.
How interest rates change what you can afford
Interest rates have a massive impact on the maximum price. The same €700/month payment over 30 years finances: about €146,600 at 4%, €166,000 at 3% and €189,300 at 2%. A 1-point rate drop lets you borrow roughly 13% more with the same monthly payment. This is why timing matters: low rates increase purchasing power, but they also push prices up, and the two effects often cancel each other out.
Common mistakes when calculating your maximum
The most common mistake is confusing the bank's maximum approval with the right price for your situation. Other frequent errors: not budgeting for closing costs (the bank won't cover them), buying at the limit with no emergency reserve, ignoring how a variable rate rising 2–3 points would affect monthly payments, and overlooking the running cost of ownership: community fees, property taxes, insurance and maintenance, which can add €200–€400 a month on top of the mortgage.
Frequently asked questions
How much house can I afford?
Start from the monthly payment you can sustain (around 30–35% of net income), convert it into a loan amount and add the savings you have for the down payment and costs.
Is 4–5 times salary a good rule?
It is a quick reference, but the real limit comes from the monthly payment, interest rate and your savings.
How much do interest rates change my budget?
A lot: with the same payment, a 1-point lower rate lets you borrow roughly 13% more over 30 years.
What do people forget in the calculation?
Taxes and closing costs, maintenance, insurance and keeping an emergency fund after the purchase.
