Mortgage & Real Estate

Price a home loan properly — payment, escrow, affordability, equity, closing costs and whether renting still beats buying where you live.

A mortgage quote is one number hiding six. The rate you are shown is not the payment, the payment is not the monthly cost, and the monthly cost is not what the house ends up costing you. These ten tools separate those layers.

Most people arrive at the mortgage calculator first, and it is the fullest tool on the site: principal and interest, property tax, insurance, HOA dues and private mortgage insurance, with a complete amortisation schedule underneath. That schedule is the part worth reading. On a thirty-year loan at 6.5%, the first payment is roughly 78% interest, and it takes about eighteen years before principal overtakes interest in a single payment.

Before the payment comes the ceiling. The affordability calculator works backwards from income, existing debts and a deposit to the price a 28/36 debt-to-income test will actually approve — usually a good deal less than the figure a portal suggests. The down payment calculator covers the cash side, including where the 20% PMI threshold sits, and the closing cost calculator itemises the fees that appear on a settlement statement and surprise first-time buyers.

For people who already own, home equity shows what you have built and how much of it a lender will actually lend against. For landlords, rental yield and property investment turn rent, price and costs into gross yield, net yield, cap rate and cash-on-cash return. And for the question that never has a clean answer, the rent vs buy calculator runs both scenarios across your real horizon and finds the break-even year.

How to choose the right tool

Affordability before payment. If you have not chosen a house yet, the affordability calculator is the right starting point — it tells you the price band. The mortgage calculator answers the next question, once a price exists.

Mortgage against home loan. The mortgage calculator is built around the US-style escrowed payment: tax and insurance collected monthly alongside principal and interest. The home loan calculator is the EMI-style tool used in most of the rest of the world, and it adds a prepayment field that shows the interest saved and the months cut from the term. Same mathematics underneath; different conventions on top.

Yield against full investment analysis. Use rental yield for a quick screen when comparing several properties — gross and net yield are enough to reject most of them. Use property investment once a deal is worth real attention, because cash-on-cash return accounts for financing and yield does not.

One habit worth adopting: run the mortgage calculator, then add one extra payment a year and run it again. On a typical thirty-year loan that single change removes four to five years and a substantial share of the total interest, and it is easier to arrange than any rate negotiation.

Mortgage questions

The common lender test is 28/36: housing costs no more than 28% of gross monthly income, and total debt payments no more than 36%. The affordability calculator applies both and reports the lower of the two, which is what a lender does.

Usually day-count convention, fees folded into the quoted APR, or a first payment date more than a month after drawdown. Differences of a few units of currency are normal; anything larger is worth asking about. How we calculate explains our assumptions.

Conventionally when your loan-to-value reaches 80% — that is, when equity reaches 20% of the original value — and automatically at 78% under US rules for many loans. The home equity calculator shows where you currently stand, and rules vary by lender and country.

A 15-year term costs far less in total interest and far more each month. Run both in the mortgage calculator and compare the monthly figure against your budget, not just the total. A 30-year loan with voluntary extra payments gives most of the saving and keeps the flexibility.

It depends entirely on the market and on financing costs, so treat any universal number with suspicion. What matters more is whether net yield — after management, maintenance, insurance, tax and vacancy — comfortably exceeds your cost of borrowing. If it does not, the deal relies on appreciation.
