Frequently asked questions

What does Home Affordability Calculator do?

Find the maximum home price you can afford from your income, debts and down payment, using the 28/36 debt-to-income rules.

When would I actually use this?

Before making an offer: what the bank will lend, what the purchase costs on top of the price, and how much deposit closes the gap.

What is the most common mistake?

Budgeting for the price and forgetting the acquisition costs. Notary fees, transfer duty and registration add between 2% and 15% depending on the country — enough to sink an offer.

How is Home Affordability Calculator different from Home Equity Calculator?

They sit next to each other but answer different questions: Home Equity Calculator is the one to open when you need it to work out the equity in your home from its value and your mortgage balance, with LTV, borrowable amount and a future projection. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

Rent Affordability Calculator is the closest one after this: See how much rent you can afford using the 30% rule and a debt-adjusted 28/36 rule, and test a target rent.

What else is worth having open alongside it?

Housing Appreciation Calculator and Interest-Only Mortgage Calculator — they come up in the same task often enough to be worth a second tab.

Where do the figures come from?

Fee scales and duty rates are published per country and per region, and they change with each finance act. Lending limits also depend on the bank's own policy, not only on the regulator's debt-to-income cap.

ExplainerHow Much House Can You Actually Afford?Three constraints decide it — the deposit, the lender's ratio and the payment you can live with — and they bind in a different order for different buyers. Same $90,000 income, three answers: $230,769, $355,360 and $431,922.ExplainerWhat Is Loan-to-Value (LTV), and Which Bands Actually Change AnythingLoan divided by the lower of price and appraised value. The bands at 80, 90 and 95 percent are where pricing steps — and a valuation that comes in low moves you across one without you touching the deposit.ExplainerHome Equity Is Not One NumberValue minus debt gives $139,167. After the costs of selling it is $111,867. What a lender will actually let you borrow against it is $55,167. Same house, same day, three answers — and the third is the one that governs.How-toHow to Compare Price Per Square Foot Without Comparing Two Different ThingsThe division takes a second; the trap is the area. A listing that looks 6 percent cheaper per square foot turns out to be 17 percent more expensive once both are measured the same way.ComparisonComparing Two Mortgage Offers ProperlyThe rate is not the comparison. Over a five-year holding period the 6.25 percent offer with $2,000 of fees beats the 5.875 percent offer with $12,000 by $2,485.73; the crossover falls at month 80, not at the month 103 the simple payback suggests.How-toHow Much Storage Space Do You Need?You are sold floor area and you use volume. A 10 by 10 unit is 800 cubic feet gross but 595 usable, and a one-bedroom home itemised piece by piece comes to 635.75 packed — so the unit advertised for it only just holds it.
