Selling a property in Cardiff — especially in sought-after areas like Llandaff and Pontcanna — is both an exciting opportunity and a significant undertaking. Naturally, you’ll want to achieve the highest possible price for your home, but even the most beautiful properties can lose value if certain mistakes are made.
The decisions that impact resale value often happen long before you put your home on the market. Small missteps in maintenance, presentation, or pricing can have a lasting effect — but the good news is, they’re avoidable with the right approach.
At Fortis, we’ve helped countless Cardiff homeowners maximise their property’s value. Here are the five most common mistakes we see — and how to fix them.
It’s natural to believe your home is worth more than your neighbour’s — particularly after a renovation or upgrade. But in reality, your property is only worth what a buyer is willing to pay.
If your asking price is set too high, it may sit on the market for months without serious interest. Prolonged listings often make buyers suspicious, and you may end up reducing the price significantly, which can undermine confidence and invite lower offers.
Fortis Tip: Start with an honest, evidence-based valuation. At Fortis, we combine local market knowledge with comparable property data from Llandaff, Pontcanna, and surrounding Cardiff areas to ensure your home is competitively priced from day one.
First impressions count. No matter how spacious or well-located your home, if it feels unclean, buyers may mentally subtract from their offer — or walk away altogether.
Stains on carpets, mould on grout, or sticky door handles are instant red flags. These details may seem small to you, but to a buyer, they signal poor upkeep. Even in premium Cardiff postcodes, presentation matters.
Fortis Tip: Invest in professional cleaning before marketing your home. Pay extra attention to high-traffic areas, skirting boards, windows, and overlooked corners. A sparkling home feels well cared for — and that translates into higher perceived value.
From leaky taps to outdated boilers, deferred maintenance can cost you when it’s time to sell. Buyers will often request reductions for repairs or walk away entirely if they suspect hidden issues.
In Cardiff’s older housing stock — from Victorian terraces in Pontcanna to character homes in Llandaff — proactive upkeep is particularly important. Plumbing, electrics, roofing, and heating systems should all be in good working order.
Fortis Tip: Keep detailed records of all maintenance, including annual boiler servicing, roof inspections, and electrical checks. Buyers are reassured by a documented history of care and are more likely to pay a premium for a “move-in ready” home.
Décor may be personal, but buyers need to see your home as a blank canvas for their own lifestyle. Outdated design trends — heavy drapes, dated tiles, or worn carpets — can make a property feel tired and reduce perceived value.
Modern, neutral interiors tend to perform best in Cardiff’s high-demand areas, as they photograph well and appeal to a broader audience.
Fortis Tip: If a full redecoration isn’t in budget, focus on cost-effective upgrades: repaint walls in neutral tones, replace old light fittings, and swap worn cupboard handles for sleek, modern ones. Small touches can significantly freshen the space.
Your home may reflect your personality, but bold paint colours, eccentric wallpaper, or overly specific décor can limit buyer appeal.
If buyers can’t envision themselves living in your property, they’re less likely to make a strong offer. This is especially true in competitive Cardiff markets, where buyers often compare multiple homes in quick succession.
Fortis Tip: Neutralise your décor before marketing your property. Light, natural tones create a welcoming atmosphere and help buyers mentally “move in” during viewings. Think show home simplicity, with just enough warmth to make it feel inviting.
In premium Cardiff locations, buyers expect quality. Presentation, maintenance, and realistic pricing are key to achieving the best result. Even small oversights can reduce perceived value, slow down your sale, or lead to price negotiations you’d rather avoid.
By taking a proactive approach — and working with a local agent who understands your area — you can position your property to sell quickly and for the best possible price.

Should I deep clean before viewings?
Yes — a spotless home makes a strong impression and reassures buyers about the level of care the property has received.
Does plumbing and heating really affect my sale?
Absolutely. Buyers will factor in the cost of repairs or replacements, so well-maintained systems can directly influence your asking price.
Do I need to redecorate before selling?
If your décor is outdated or highly personalised, updating to a modern, neutral style can broaden your property’s appeal and attract higher offers.
