Bidding Above The Askingprice? This Is How You Do It
The housing market is tight and fast-paced. Homes are off the market before you know it, often selling well above the asking price. You know you need to bid above asking to have a chance, but how much?
​
An effective bidding strategy starts with accurately determining the market value of the home. With SlimBieden’s data-driven approach, you receive personalized bidding advice, helping you make a successful offer on your dream house.
How do you determine what to offer on a house?
The asking price and property features don’t tell the whole story. What you really want to know is what the house is worth in today’s market and what similar homes in the same neighborhood have actually sold for.​
​Ideally, you should have access to:
-
Selling prices of comparable homes.
-
Insights into average overbidding in the area.
-
The condition of the home and renovation potential.
-
Location, popularity, and level of competition.
​
Why overbidding is inevitable
In today’s market, bidding above the asking price is often unavoidable. According to the Funda Index (Q2 2025):
-
23% of home seekers expect to bid between 5% and 10% above the asking price.
-
25% believe that even more is needed to have a chance.​
These expectations match reality. In the third quarter of 2025, 71% of homes were sold above asking price, with an average overbid of 4.9%. The average transaction price also kept rising: in September 2025 it was 7% higher than in the same period the year before. This upward trend has been visible in every month of 2025.
In short: in many regions, overbidding is not just common, but necessary to even stand a chance. At the same time, buyers often don’t know exactly how much they should overbid — and that’s where things go wrong.
Common mistakes when bidding on a house
Because you’re eager to secure a home, you’re more likely to make mistakes. With pressure from the market, competition, and time constraints, it becomes difficult to make rational choices. Without a clear plan or solid information, a misstep is easily made.​
These are the most common mistakes we see:
-
Blind overbidding: Offering thousands of euros extra without any insight into what similar homes are selling for.
-
Bidding based on emotion: Letting enthusiasm, pressure, or the fear of missing out guide you, without a clear plan.
-
Being too cautious: Out of fear of overpaying, you bid too low and are immediately out of the running.
​
A smart offer isn’t a gamble, it’s a well-informed decision based on facts, market insights, and smart timing.
This is how you do determine the right offer
There’s a lot of competition, and determining the right amount takes more than just gut feeling or a quick glance at the asking price. Especially if you don’t have a buying agent, it’s difficult to assess what a property is truly worth. SlimBieden helps you there. You receive carefully constructed advice, based on in-depth data about the property, the neighborhood, recent selling prices, and current overbidding percentages.
We draw from a database of over 5,8 million property transactions (94,5% of all registered home sales at the Dutch land registry over the past 20 years) and analyze more than 1.600 property features. This gives you advice that’s not only fast, but also firmly backed by data.
