Buying a house can feel like a dream come true, especially when it’s your first venture into the market and comes after years of planning. Even if you’ve moved several times by now, the exhilaration of a new place to call home never gets old.

As you tour potential properties, you may be envisioning how you will arrange and decorate once you take possession. Before you make that final commitment, however, it’s also essential to do some research and due diligence so your transition remains a positive experience.

In this post, we’ll talk about the difference between a minor imperfection and what might be a red flag to reconsider your choices.

Defining Your Criteria

Some attributes, like signs of Kitec plumbing or horizontal cracks in the basement foundation, are enough to give any buyer pause. These repairs are not small, and they are certainly something to consider when looking at a home.

If you are planning for a substantial remodel, you might be more open to certain flaws that will be taken care of in the process anyway. For example, a roof that needs to be replaced is a red flag for many buyers, but perhaps not if you intend to build a second-floor addition. Even in that case, deficiencies can be a point of negotiation. Any price concession helps to make your remodel more affordable.

A buyer without the knowledge or resources to invest in major renovations will need to be more careful. Nearly everyone will add some personal touches and make some upgrades over time. It’s the urgent repairs you don’t expect that make owning your new home stressful rather than exciting.


Expert guidance is the key to finding and securing the right house, whether you’re on the hunt for something move-in ready or a fixer-upper. Learn more about choosing an agent in the posts below:


Don’t Panic at Surface Imperfections

Seeing something ominous like a water mark on the ceiling can be enough to make you run out the door. Your first thoughts might be that the roof is leaking, and you don’t even want to imagine how much that might cost to repair. It’s definitely worth a deeper investigation, but you don’t need to cross this option off your list just yet.

  • The mark could be something as simple as a stain from a bad spill or an overflowing bathtub from years ago. A little primer and paint might make it disappear, no harm no foul.
  • Discolouration along the visible concrete at the base of the house can be alarming. Is it the foundation? It could be a sign of trouble, or it could be a relatively inexpensive grading issue.
  • Of all the red flags to watch out for, water in the basement is often public enemy number one. Your mind is immediately calculating the costs for an outdoor dig, and it could add up to the equivalent of a down payment!

Foundation issues are a primary cause for concern, but a little moisture isn’t always the disaster it seems to be. In some cases, the eavestroughs are plugged and rain is overflowing onto the ground right next to the house.

Clean the gutters and ensure the downspouts are far enough away, and all may be well. Working with an experienced professional will help you discern between a true dealbreaker and a relatively simple fix that looks worse than it is.

Signs of Real Danger to Watch Out For

A flaw that appears to be simple but is actually a major problem is one of the toughest challenges of buying a house. Many danger signs can be tough to spot with an untrained eye.

For example, you visit an open house, and the basement has a slight smell of fresh paint. It doesn’t even occur to you to be worried. Every seller paints before listing their house; what’s the difference in this case? 

If the basement ceiling has been repainted, it could simply be because a diligent homeowner wants to make a positive first impression. On rare occasions, they could also be trying to hide an active water leak, or worse, mould.

In the same vein, recently installed carpet could be an innocent homeowner wanting to make their property look its best. Or it could be covering a pet-destroyed floor that needs to be entirely ripped out and replaced.

Learning to discern between real problems and minor issues that are no big deal can take years of training and experience. Fortunately, buyers have the option of a home inspection by a licensed inspector. You can also protect your interests by including certain conditions on your offer whenever the market allows.

They may not be able to detect everything, but they will give you detailed information you need to decide whether or not to negotiate or to simply move on.

Flexibility Can Open Many Doors!

As a buyer, you want to ensure you are getting the absolute best value from your purchase. If you insist on a home that is perfect in every way, you may need to be prepared to spend more. Even in slow markets, buyers compete over the best listings that need the least amount of work.

By remaining flexible, you could find properties that need a little care to make them check all of your boxes. In some situations, this can be the most affordable path, especially if any flaws are cosmetic rather than functional.

You can’t necessarily wait to replace a broken furnace if we’re heading into the winter months. However, you can live in a home even if the bathroom is a little outdated or the backsplash in the kitchen really isn’t your style. As time goes on and your budget allows, you can invest in those minor changes to make your house feel like home.

The combination of due diligence and flexibility can mean more possibilities are open to you. Your real estate agent will be there to protect you and guide you straight to your ideal home.
