- A property is worth what comparable properties actually sell or rent for, not what the owner hopes.
- Compare size, condition, location, title and facilities.
- For large deals, ask a qualified valuer for a professional opinion.
The Short Answer
A property is worth what comparable properties actually sell or rent for, adjusted for differences in size, condition, location and documents. It is not what the owner hopes, what the agent says or what a neighbour paid long ago. You can make a good first estimate yourself by comparing real examples, and for large deals you should ask a qualified valuer for a professional opinion. This guide is general information, not a formal valuation.
Step 1: Gather Comparable Properties
Find properties that are similar in type, size and area that have sold or rented recently. Asking prices are only a starting point, because many sell for less. Ask agents, neighbours, recent buyers and landlords what prices were actually agreed. Collect at least three to five examples.
Step 2: Compare the Features That Change Value
| Factor | What to compare |
|---|---|
| Location | Access, security, neighbourhood reputation, power, water and nearby services. See our neighbourhood checklist |
| Size and layout | Land size, floor area, number of bedrooms and bathrooms |
| Condition | Age, repairs needed, quality of finishes. Use our inspection checklist |
| Title and documents | A clean, verified title is worth more than a risky one. See our title guide |
| Extras | Parking, boys' quarters, generator, borehole, estate facilities |
Step 3: Adjust and Estimate
Start from the closest comparable and adjust up or down for differences. A better location or newer finishes may justify more, while repairs or a weak title lower the value. Create a range, such as lowest likely, most likely and highest likely, instead of one number. Add costs such as fees, taxes and repairs to see the true price.
Step 4: Value an Investment by Income
For a rental, compare the price with the rent you can realistically earn. Use the yield formulas in our guide on evaluating a rental property. A property that costs a lot but earns little rent may be overpriced as an investment, even if the neighbourhood is popular.
Step 5: Know the Limits of Your Estimate
Markets move, and a single sale may not represent the market. Be careful about prices that are unusually low or high, since there may be a hidden reason, such as a title dispute or a rushed sale. Do not accept a valuation from a person who benefits from the sale as your only opinion.
When to Hire a Professional Valuer
For a large purchase, a loan application, an inheritance, a dispute or a company asset, hire a qualified estate surveyor and valuer. Ask about their registration and experience, and agree the fee and the scope in writing. Lenders may also require their own valuation, as explained in our guide to home financing options.
Action Checklist
- Collect three to five recent, similar sales or rents
- Confirm real prices, not only asking prices
- Compare location, size, condition, title and extras
- Estimate a range, not just one number
- Check yield for rental properties
- Verify the title before relying on any value
- Hire a qualified valuer for large or important deals
