The Battle of Property Valuation Tools: Who’s the Most Accurate?
Published 28 February 2025
TL;DR / Summary:
– The same property can get very different valuations depending on which tool you use.
– In our tests, some tools came significantly closer to the actual transacted price than others.
– Each tool offers different insights beyond just the estimated value, from price trends to rental estimates to cash proceeds.
– Use these tools as a starting point, then verify with a property agent before making any moves.
Among property valuation tools in Singapore, the most accurate ones tend to be those with the most current and comprehensive transaction data behind them. And since not every tool is working with the same data, the estimates you get can vary more than you’d expect.
So to find out which tool actually gets it right, we tested five of the most popular free property valuation tools in Singapore on the same property to see exactly how they compare.

HDB Resale Flat Property Valuation Comparison
Now, what’s the estimated value of a 4-room HDB resale flat (818 sq ft) in Toa Payoh Central?
SRX – X-Value Home Report
$732,000
99.co – Property Value Tool
$732,000
PropertyGuru – Property Valuation Tool
$799,634
EdgeProp – Edge Fair Value
$750,000
$745,000
Based on the most recent transaction of a 4-room flat in the same block, which was sold at $750,000, the closest estimated home value was from EdgeProp’s Edge Fair Value and Ohmyhome’s HomerAI.
Take note that these are specific property examples. As a rule of thumb, your estimated home value should not be significantly lower or higher than the last transacted price in your HDB block, condo development, or surrounding area. Having an experienced and knowledgeable property agent will help you determine the best and fairest selling price for your home.

What Each Property Valuation Tool Does Differently
Getting a valuation is one thing, but each tool offers a different set of insights that could change how you approach your home sale.
1. SRX’s X-Value Home Report
Shows how much your property valuation has changed in 10 years and compares it to the transacted prices of properties in your region, be it CCR, RCR, and OCR, and all over Singapore.
2. PropertyGuru’s Property Valuation Tool
It will tell you directly if your property valuation is above or below average based on past transactions of similar-sized units in your district over time.
3. 99.co’s Property Valuation Tool
Don’t just provide your estimated home value, but also your estimated rental value should you decide to put your home up for rent instead of for sale.
How is Ohmyhome’s Property Valuation Tool HomerAI Different From the Rest?
Upon registering your home with HomerAI by Ohmyhome, all your property details are securely stored within your personalised dashboard. This means that you don’t need to manually input all your home details to check your property valuation – it’s available at all times and is even updated every month.
So while you’re planning your home selling journey, you’ll get access to all the information you need about your home anytime, anywhere.
Beyond the Valuation Number
It’s worth noting that capital gains data on SRX and PropertyGuru is based on officially recorded property transactions with URA. If you own an HDB flat, this data may not always be available, so it’s always good practice to supplement any tool’s estimates with your own research.
That said, Ohmyhome’s HomerAI, 99.co, and PropertyGuru all let you calculate how much you’ve gained since purchasing your home. Just key in your original purchase date and price and the tool takes care of the rest — a useful way to get a sense of whether the timing is right to sell.
If you want to go a step further, HomerAI’s Cash Proceeds Calculator gives you a clearer picture of what you’d actually walk away with after the sale. Factor in your ideal selling price, outstanding loan, and CPF monies used, and you get a realistic estimate of your net proceeds, which makes planning your next move a whole lot easier.

Frequently Asked Questions
1. How often are property valuation tools in Singapore updated?
Most tools update their estimates monthly, though some refresh more frequently based on new transaction data submitted to URA and HDB. For the most current figure, it’s worth checking back regularly especially in an active market.
2. Can I use a property valuation tool to negotiate my selling price with a buyer?
You can reference it as a starting point, but valuation tools give estimates based on historical data and may not fully account for your home’s condition, recent renovations, or current buyer demand. A property agent can help you translate that estimate into a realistic and defensible asking price.
3. Is a property valuation tool accurate enough to replace a professional valuation?
Online valuation tools are useful for getting a quick ballpark figure, but they are not a substitute for a formal valuation done by a licensed valuer, which is typically required for bank loans and legal transactions. Think of them as a helpful first step rather than a final answer.
