Start with the monthly picture

A purchase price tells you what the home costs to acquire. The monthly budget asks a different question: what could it cost to own and live in it?

Use actual bills and your own quotes where possible. A realistic budget can include a bond repayment, municipal rates, levies, utilities, insurance, a maintenance reserve and the cost of your regular commute.

1. The bond repayment

Your deposit reduces the amount financed. The repayment also depends on the interest rate and term. Enter a lender’s quoted rate rather than assuming a default is the rate you will receive.

Changing the deposit, interest rate or term changes the repayment. A lower monthly repayment does not by itself describe the total lifetime cost of the loan. The calculator estimates a standard fixed-input amortising payment; it does not model future rate changes or a bank’s full lending terms.

Use the ownership-budget rate table to see what one or two percentage points more interest would do to the monthly payment. The lifetime-interest summary assumes your entered rate throughout the term. Neither is a rate forecast or lender approval.

2. Rates, levies and utilities

Ask for recent municipal accounts and levy statements. Confirm which services are included and which you will pay separately. Water, electricity, refuse, sewerage and other charges may be billed differently for different properties.

For a sectional-title home or a property in an estate, ask about ordinary levies and any special levies. Use the amounts for the actual property instead of a city-wide average.

3. Insurance and maintenance

Get an insurance quote for the property and your situation. Do not treat an example premium as a confirmed insurance cost.

A maintenance reserve is money set aside for repairs. The example starts at 1% of the price per year, divided by 12; this is an illustrative budgeting assumption, not a prediction of repair costs. Adjust it for what an independent inspection reveals. Changing the price later does not automatically replace your chosen reserve.

4. The commute you will actually make

Enter a realistic one-way distance, the number of days you expect to travel and your allowance for fuel and wear. The monthly estimate includes return trips.

A straight-line map distance is not a road route. Check the route yourself and consider traffic, tolls, parking or public-transport costs separately where they matter. There is no live traffic-time estimate in this MVP.

Keep once-off costs on a separate list

Monthly ownership costs are only part of the purchase decision. Keep a separate list for transfer duty where applicable, conveyancing, bond registration, moving and any immediate work on the home.

The budget tab provides a dated SARS transfer-duty estimate alongside your deposit, separately from the monthly total. Confirm the acquisition date, taxable value and any VAT or exemption with your conveyancer. Legal fees and other purchase costs require written quotes.

Compare homes using the same questions

Save each report with its own assumptions. A useful comparison shows the monthly costs and the questions still open, rather than simply ranking asking prices.

A municipal audit and police-precinct statistics provide context for investigation. They are not a street-level safety guarantee or a substitute for visiting the neighbourhood and checking the property.
