Many Singapore homeowners choose the DIY route to save on agent commissions. But hidden costs — in time, marketing, and admin — can quickly add up.

This guide covers 7 common mistakes that DIY HDB sellers face, and how Cosell’s $2,699 fixed-fee service helps you avoid them while boosting visibility and simplifying the sale.

1. Professional and 3D Photography Costs

1. Professional and 3D
Photography Costs

DIY sellers typically don't have access to 3D camera equipment, which significantly enhances virtual tours and attracts higher buyer interest. Hiring a professional service to create a 3D virtual tour usually costs between $300 to $500. We've witnessed multiple instances where DIY sellers, attempting to save on marketing costs, inadvertently create poorly presented listings that reduce buyer interest.

Cosell Advantage:
With Cosell, sellers gain professional guidance to affordable, high-quality photography and advanced 3D virtual tours. This ensures your property stands out prominently online, attracts more serious buyers, and helps secure a quicker, profitable sale.

2. Limited Marketing Exposure

Exposure

DIY HDB home sellers typically list their properties on platforms like the HDB Resale Portal, Carousell, or their personal social media accounts.

While inexpensive, these platforms attract fewer serious buyers compared to premium real estate portals like PropertyGuru and 99.co—platforms exclusive to professional real estate agents.

With limited exposure, HDB sellers significantly decrease their property’s visibility to active home seekers, prolonging market exposure and increasing indirect expenses.

Cosell Advantage:
Cosell gives your property access to high-traffic real estate portals, instantly increasing its visibility and attractiveness.

The result?

A faster sale, more competitive offers, and substantial cost savings.

3. Incorrect Pricing and Valuation Mistakes

Valuation Mistakes

DIY home sellers often price their properties inaccurately due to limited access to comprehensive market data. This often results in prolonged market exposure, multiple price adjustments, and ultimately, lost revenue.

Cosell Advantage:
Our professional valuation and pricing assessments leverage real-time market data to help you accurately price your property from day one, minimizing time spent on the market and maximizing your profit potential.

4. Legal and Conveyancing Fees

Conveyancing Fees

Property selling involves detailed paperwork, contracts, and conveyancing processes. DIY sellers frequently encounter unexpected legal complexities, often scrambling to hire last-minute professional services, leading to surprise EXTRA expenses upwards of $1,500.

Cosell Advantage:

With clear guidance through the entire documentation process, Cosell ensures transparency and predictability. You can avoid hidden extra legal costs and unexpected conveyancing fees entirely.

5. Opportunity Costs and Lost Earnings

and Lost Earnings

Home viewings, buyer negotiations, and administrative tasks consume significant personal time.

DIY sellers often underestimate this opportunity cost, which can amount to thousands in lost productivity and income.

Another hidden cost: even if you are flexible with your viewing schedule, traditional agents may not be. Many potential viewings are lost simply because the agent is unavailable at times when buyers want to view — leading to missed opportunities and delays in offers.

Cosell Advantage:
Cosell significantly streamlines your selling process. While you manage viewings on your own schedule — ensuring no missed opportunities — we handle all the administrative work, buyer communications, marketing, and paperwork.

This saves you valuable time, helps maintain your productivity, and maximizes your earnings potential while accelerating your sale.

6. Negotiation Errors

Negotiating effectively requires professional experience. DIY sellers, often lacking such expertise, may be easily pressured into accepting lower-than-optimal offers, costing thousands in potential profits.

Cosell Advantage:
Our professional negotiation support empowers sellers to handle price negotiations confidently, helping you secure the best possible offers and avoid costly mistakes.

7. Administrative and Post-Sale Expenses

Post-Sale Expenses

Administrative duties don't end once an offer is accepted. Many HDB sellers face unexpected administrative fees or post-sale requirements, eroding their anticipated savings.

Cosell Advantage:
Cosell’s fixed-fee model transparently covers all processes, clearly outlining potential expenses in advance to ensure no surprise costs occur post-sale.

Real-Life Example: How Hidden Costs Add Up

Real-Life Example:
How Hidden Costs Add Up

Recently, a couple decided to sell their 4-room HDB flat in Sengkang on their own, hoping to save on agent commissions.

Initially confident, they began by using their smartphones for property photos and videos, thinking it was sufficient. Unfortunately, their listing attracted minimal interest.

To market their home, they used limited platforms like Carousell, the HDB Resale Portal, and their personal social media accounts. While these platforms were inexpensive, they soon noticed most serious buyers were looking on premium platforms like PropertyGuru and 99.co, which they couldn’t access as DIY sellers.
This drastically limited their market visibility, leading to fewer interested buyers and prolonging the selling period.

They listed their HDB for 7 months without any offer.

They decides to adjust their price and eventually sold below the actual market value, losing around $10,000 to $15,000 in potential earnings.

Legal paperwork and conveyancing were also more complex than anticipated. Lacking initial legal guidance, they encountered unexpected conveyancing fees and last-minute expenses, costing approximately $1,000 extra. Furthermore, managing their own home viewings required them to take frequent leaves from work.

In total, their DIY selling effort—which was supposed to be cost-saving—resulted in more than $8,000 in hidden expenses and lost income.

Had they chosen Cosell’s clear and predictable fixed-fee solution (just $2,699), they would have immediately benefited from professional guidance, strategic property marketing, higher market visibility, accurate property valuation, expert negotiation support, and significant financial savings.

This real-life case highlights precisely why Cosell’s fixed-fee approach offers HDB owners a smarter, more cost-effective solution to DIY selling.
