Buying a new home is one of the most exciting investments you will ever make, but it is also one of the largest. When you walk into a viewing, it is incredibly easy to get swept away by beautifully staged furniture, a fresh coat of paint, or a stunning modern kitchen.
However, beneath a polished surface can lie costly structural or legal issues. Knowing exactly what to look for when buying a house can mean the difference between finding your dream home or inheriting a financial nightmare.
To help you navigate your next viewing with confidence, the team at Simon Blyth has compiled this essential walkthrough checklist of what to check, ask, and observe before making an offer.
1. The Exterior: First Impressions and Structural Integrity
Before you even step through the front door, take a slow walk around the outside of the property. Fixing structural or roof defects can cost thousands, so check these key areas first:
-
The Roof: Are there any cracked, missing, or slipping tiles? Does the roofline look straight, or is there a noticeable sag?
-
Guttering and Pipes: Look for signs of leaks, rust, or damp staining on the external brickwork. If it’s raining during your viewing, this is a perfect time to see if the gutters are overflowing.
-
Brickwork and Foundations: Keep an eye out for large, diagonal cracks in the brickwork or rendering. While minor hairline cracks are common as houses settle, deep structural cracks could indicate subsidence.
-
The Surrounding Area: Note which way the garden faces. A south-facing garden is highly sought after for maximum sunlight. Also, look at neighbouring properties – are they well-maintained, or could they impact your future resale value?
2. The Interior: Spotting Hidden Warning Signs
Once inside, switch your focus from the décor to the core health of the building.
-
The Damp Test: Damp is one of the most common issues in UK properties. Look closely at the ceilings and baseboards for peeling wallpaper, flaky plaster, or dark patches. Don’t be afraid to use your senses – a musty, earthy smell is a major giveaway for hidden damp.
-
Water Pressure and Plumbing: Turn on the taps to check the water pressure and see how quickly the water heats up. Flush the toilets to ensure the system runs smoothly.
-
Storage Space: Modern homes can sometimes compromise on storage. Look for built-in cupboards, assess the size of the kitchen units, and ask if there is accessible loft space.
-
Windows and Locks: Open and close a few windows. If the property has double glazing, check for condensation between the glass panes – this indicates a blown seal, meaning the window will need replacing to maintain energy efficiency.
3. The Power Checklist: Heating and Electrics
Replacing a boiler or rewiring a house can severely impact your post-move budget. Always inspect the utility systems:
-
The Boiler: Ask how old the boiler is and request to see its service history. If a boiler is more than 10 to 15 years old, you should factor the cost of a replacement into your negotiations.
-
The Fuse Board and Electrics: Take a look at the electricity meter and consumer unit (fuse box). If it features old-fashioned rewireable fuses rather than modern circuit breakers, the property may require a partial or full rewire.
Crucial Questions to Ask the Estate Agent
A physical inspection only tells half the story. To get the full picture, make sure to ask the managing estate agent these key background questions:
-
How long has the property been on the market? If it has been listed for several months, ask if there have been any previous chain collapses or issues raised in past surveys.
-
What is the seller’s situation? Are they in a forward chain, or have they already found a property? A seller looking for a quick break or selling a vacant probate property may be more open to flexible offers.
-
What is included in the sale? Don’t assume the garden shed, light fixtures, or integrated kitchen appliances are automatically yours. Clarify exactly what forms part of the final inventory.
-
How much are the running costs? Ask to see the Energy Performance Certificate (EPC) rating and inquire about the average utility bills and Council Tax band.
The Final, Most Important Step: Secure a Professional Survey
While this checklist will help you filter out clear warning signs during an initial viewing, it does not replace a professional home survey. Once your offer is accepted, instructing an independent RICS surveyor is the ultimate insurance policy. They have the specialist tools and expertise to check the property thoroughly from top to bottom.
