The property industry has always attracted people looking for long-term returns, but success often depends on avoiding simple mistakes. Joe Martin Bindley, founder of Peninsular Property, has spent years building a reputation in the property market through practical, grounded advice.

As someone who’s been deeply involved in both property management and investment, Joe knows where many new buyers go wrong.

He believes that avoiding poor decisions before you buy is just as important as what you do after the sale. Rushing in, trusting the wrong people or skipping important checks can affect the worth of property and lead to expensive problems down the line.

Below are Joe’s best tips on what not to do before investing in property:

#1 Don’t skip local research

One of the biggest mistakes new investors make is not spending enough time understanding the area in which they’re buying. A property might look appealing online, but the local environment can tell a very different story.

Joe Martin Bindley recommends physically visiting the location and speaking to people who live or work nearby. This can reveal things that won’t show up on a property listing, like high turnover of tenants, noise issues or signs of local decline.

• Walk the area during the day and again in the evening
• Research school catchments, public transport and any planned developments

Numbers don’t show you what it’s like to own there. People do –  says Joe Martin Bindley

#2 Don’t be guided by price alone

Many first-time buyers make the mistake of thinking that a low purchase price guarantees a good investment. Joe has seen this go wrong time and again. A cheaper property might look like a win, but without thinking through the risks, it can quickly drain your finances.

If the property needs major renovation, or if tenant demand is low, that “bargain” may take years to pay off if it ever does.

Joe Martin Bindley puts it simply: A good deal isn’t just about the price you pay. It’s about what you get back and how much hassle it takes to get there.

#3 Don’t ignore the maths

Joe Martin Bindley always highlights the importance of knowing your numbers, not roughly, but properly. Many investors make guesses about costs and income, only to get caught out later.

Forgetting to factor in things like repair costs, tax, void periods or rising mortgage rates can quickly turn a profit into a loss. In the property industry, bad maths is an expensive mistake.

• Work out all your potential costs, including insurance, tax and maintenance
• Don’t rely on “best case” rent figures that may not hold up

It’s not about being cautious. It’s about being realistic, says Joe. If the numbers don’t work, walk away.

#4 Don’t rely on the wrong advice

There’s no shortage of advice in the property world, but not all of it is worth following. Joe warns that advice from social media or forums often lacks real-world experience. Some people are trying to sell courses, some are repeating what they’ve heard and others are offering ideas that worked once but aren’t repeatable.

Joe Martin Bindley suggests sticking to those who’ve had hands-on involvement in the kind of property work you want to do. That could be local investors, experienced agents or trades people who know what it really takes to keep a rental running.

If someone can’t explain the risks, they probably don’t understand them, he adds.

#5 Don’t underestimate the work involved

New investors often underestimate how much effort goes into property management. From finding tenants and handling repairs to chasing rent or dealing with complaints, the work doesn’t stop once the property is bought.

Even with a letting agent, Joe believes the owner needs to stay involved. A good agent helps, but the investor is still responsible for the condition of the property and the experience of the tenant.

• Be ready to respond when things go wrong, especially out of hours
• Keep track of legal responsibilities like gas checks and deposit protection

A property isn’t passive if you want it to perform, says Joe. You can’t just hand over the keys and hope for the best.

Joe Martin Bindley’s advice is clear: buying property isn’t just about spotting a deal, it’s about knowing what to avoid. Whether it’s rushing in without research, ignoring the money side or relying on second-hand opinions, these mistakes can lead to stress, delays and lost income.

For investors who recognise that property is not entirely passive, exploring structured options such as a guaranteed rent scheme can help reduce risks such as void periods and inconsistent rental income. In competitive markets like London, having clearer expectations around rental income and property management responsibilities can support more predictable financial planning for landlords.

As founder of Peninsular Property, Joe has built his career on careful planning and real-world knowledge. His view is that success in the property market comes down to preparation, patience and not cutting corners. Avoiding these five common traps is a good place to start.
