Mortgage affordability
across markets

One household, several different financing questions

A mortgage comparison becomes useful when it answers a practical question: with your income, spending and cash, which financing plan has room for the home you want? A salary multiple alone cannot answer that. A payment can pass an income check while leaving too little for ordinary life, or it can fit the monthly budget but require more purchase cash than you have.

This article brings together the MMDAI models for the United Kingdom, Poland, Spain, France, Germany, Italy, Switzerland and the United States. It compares owner-occupied purchase scenarios and keeps the household’s income, living costs, debts, savings and retained reserve consistent in euro terms. Each market retains the stated example financing and purchase-cost assumptions from its local model. The country guides let you examine a different financing plan.

The local mortgage rates and fees are fixed planning examples; household amounts are editable; currency conversion uses fixed planning assumptions. They are not live quotes, typical national prices or evidence that a lender will accept a particular borrower. Use the country pages to enter actual local offers and property costs before interpreting a difference as part of your buying decision.

Keep the income definitions separate

Annual gross income and monthly take-home income are different inputs. Neither is estimated from the other. The UK example uses a gross-income loan multiple alongside a take-home budget. The US example tests housing and total debt against gross income, then checks ownership costs against net income. Poland, Spain and Italy use their selected net-income ratios as well as household spending.

France normally uses net income before income tax. To keep one household scenario, this comparison uses your monthly take-home income as a conservative proxy for that test, without estimating tax or asking for another income. The French country guide accepts your actual qualifying income. Switzerland uses theoretical annual housing cost against gross income, with a separate net-budget check.

A stress payment is not the same thing everywhere

For a repayment mortgage, a higher-rate comparison changes principal and interest on the initial loan. Poland also uses a shorter assessment term when the contractual term is longer. Germany tests the debt remaining after the fixed-interest period against a later repayment term. Switzerland adds theoretical interest, required partial amortisation and maintenance instead of pretending the entire mortgage is repaid as a conventional annuity.

The assessed cost therefore means the monthly ownership cost used for this model’s household check. It includes the entered ownership allowance where relevant. In Germany it uses the larger payment across the initial and refinancing cases; in Switzerland it includes partial amortisation and maintenance. The explanation beneath the selected result identifies the basis. It is not a forecast that every fixed-rate loan will change.

Compare purchasing funds separately from the payment

Available purchase cash is savings minus the reserve you retain. The reserve stays outside the transaction. A reserve larger than savings causes the cash checks to fail without changing either input. Purchase cash includes the price paid from your own funds and the taxes, fees or cost provisions in the selected scenario. A deposit already paid is not subtracted here: it is still part of the total money committed to buying.

Switzerland adds a source-of-funds distinction. The Swiss result shows purchase cash needed outside the second pillar. This comparison assumes no pension withdrawal. It does not treat a pension pledge as cash. The country guide explains that distinction in more detail.

Build your comparison in the text

Enter your household income, monthly spending and savings. The article finds the highest property price that fits the income, household-budget and purchase-cash checks in each market. All amounts are shown in euros.

Inspect the result for one market

Choose a country to see how much property you could afford there, then inspect the mortgage, monthly budget and purchase funds at that price.

What stays fixed during the price search?

Your household inputs and each market’s example financing and fee assumptions stay fixed while the model searches for the affordable price. Candidate price changes the mortgage, equity and price-linked costs. The deposit or financing percentage is retained; the search does not optimize how much cash you choose to put into the price.

For Spain, Italy and Switzerland, this World scenario uses a fixed example valuation percentage of each candidate price. Spain also uses a tax-reference percentage. The example uses 100% of price, so these values move with price. This makes the comparison a price-range scenario rather than a search tied to one appraisal. A real property may have a lower valuation or a higher tax reference: use the country article to enter the actual values for a property-specific check.

Italian cadastral income and fixed cash fees remain independent of candidate price. Country tax treatment follows each stated example jurisdiction, transaction and buyer status. The maximum can stop at the World price range or a narrower local model range. If a converted input is outside a country model’s range, that result is marked outside range instead of quietly substituting a smaller income or appraisal.

Which differences should guide your next step?

If income assessment is the constraint, examine the recognized income, existing debts and the specific lending test. If household budget is the constraint, changing a headline lender ratio will not supply money for everyday life. If purchase cash is the constraint, review the price, deposit, tax treatment and costs while preserving the reserve you need.

Then use the country pages to replace the example financing terms with actual offers. A lower down payment can release purchase cash while increasing repayments or mortgage insurance. A longer term can reduce a contractual payment while leaving a shorter assessment term in place. An inexpensive initial payment can leave substantial debt to refinance later. These interactions are why the local explanation matters as much as the headline ceiling.

Cross-border eligibility, residence rights, recognition of foreign income, credit history, age, property use, loan limits and funds-transfer costs are outside this comparison. It also does not estimate personal income taxes, retirement affordability, local wages or purchasing-power parity. Those are necessary inputs to a real move or mortgage application.

Use the country guides to investigate the local income test and purchase-cost assumptions.
