What is a buy to let investment?

A buy to let investment means buying a property with the intention of renting it out, rather than living in it yourself. This allows you to potentially earn income from the rent, which should cover the mortgage payments and leave some profit. However, earnings are not guaranteed on buy to let properties, and the amount you can charge tenants will depend on local market pricing. When offering you a buy to let mortgage, lenders may assess the potential rental income as part of their criteria.

 

The property may also increase in value over time, which can be an incentive to buy. However, as with any investment, returns are not guaranteed, and it’s worth considering both the benefits and the challenges before proceeding.

Key advantages of a buy to let new build

So, is a new build buy to let a good investment? For some people, the answer is yes. You may find that new-build homes offer several practical benefits. Below, we explore some of the main reasons why you may be drawn to this type of property.

Warranty and insurance policy

One advantage of a buy to let new build is that appliances, heating systems and fixtures are often covered by warranty and insurance policies, such as the NHBC warranty and insurance policy. Check with your housebuilder for specific terms and conditions around warranties and what is covered. This can provide you, the homeowner, with peace of mind.

Energy efficiency and running costs

New-build homes are typically designed with energy efficiency in mind thanks to features such as double glazing, modern insulation and efficient heating systems. You may find your property has a higher Energy Performance Certificate (EPC) rating, which could mean lower running costs for your tenants.

New build appeal for tenants

Many tenants may be drawn to the look and feel of a new-build home. Modern finishes, modern layouts and up-to-date amenities can make a strong first impression. Developments may also include communal spaces or be in desirable locations with better transport links, which can boost their appeal to prospective tenants.

Potential drawbacks to consider

While a buy to let new build can offer many benefits, there are some factors you may want to keep in mind, such as:

 

  • Higher purchase prices. Property prices for new builds can sometimes be higher than comparable older homes. This may affect your initial rental yield
  • Competition affecting demand. You may also find that, as a new development grows, there can be competition from similar properties nearby. Over time, this may influence rental market pricing and demand
  • Evolving tax rules and interest changes. As with any buy to let investment, market conditions, interest rates and changes in legislation could also impact how much you make on your investment

It can be helpful to weigh up these drawbacks before investing in a buy to let property.

New builds vs older properties: key differences

When comparing a buy to let new build with an older home, the differences will often come down to cost, upkeep and tenant preferences. The table below highlights a few of these differences:

 

Type of property

Differences

New build property

  • May require less maintenance in the short term
  • Could offer higher energy efficiency and lower running costs
  • Might appeal to tenants seeking modern living spaces

Older property

  • May have a lower purchase price in some areas
  • Could offer more character or larger room sizes
  • They may require more frequent repairs or upgrades

If you’re exploring a buy to let property investment, the right new home will often depend on your long-term goals and how hands-on you want to be as a landlord.

Buy to let rental yields and long-term value

Rental yield is often used to measure how profitable a buy to let investment will be. To calculate it, compare your projected annual rental income with the property’s purchase price to calculate profitability. A strong yield would be between 5–8%. These yields are often used by lenders to assess whether you will be able to make the monthly mortgage payments.

 

New-build homes can sometimes deliver slightly lower initial yields due to higher purchase prices. However, they may offer better long-term value compared to older properties, thanks to their improved energy efficiency and potentially lower maintenance costs.

Factors affecting buy to let investments

Every investment is different and several factors can influence your property’s profitability. These can include:

 

  • Location and rental demand
  • Purchase price and mortgage rates
  • Property type and condition
  • Rental income potential
  • Ongoing maintenance and management costs
  • Legal and tax requirements

For example, a well-connected location with strong employment opportunities may attract more tenants. There may also be other factors that affect your buy to let property, so it is worth exploring all avenues before investing.

Who are buy to let new build properties suitable for?

A buy to let new build could be suitable for you for a range of reasons, including:

 

  • Modern fixtures, fittings and appliances
  • Energy efficient features like double or triple glazing and improved insulation
  • Lower maintenance costs initially thanks to warranties

Whether you decide on a new build or an older property as a buy to let investment, make sure to consider other factors such as location and budget (in case of changes to interest rates).

Costs to consider when investing in buy to let property

Before committing to a buy to let property investment, it’s important to understand the costs involved. These will often go beyond the initial purchase price. Common costs may include:

 

  • Deposit and mortgage fees
  • Legal and conveyancing fees
  • Letting agent or management fees
  • Maintenance and repairs
  • Insurance and safety checks

Factoring in the extra costs can help you build a more accurate picture of your potential returns.

Is Stamp Duty higher for buy to let properties?

A buy to let property is considered an additional property which means your Stamp Duty costs will be higher than if you were replacing your primary residence. You will need to pay a 5% surcharge on the entire purchase price, in addition to the standard rates.

Expert insight: what makes a strong buy to let investment

We spoke to a David Wilson Homes mortgage adviser, about what makes a strong buy to let property investment. Here's what he said:

 

“A strong buy to let investment will often combine several key qualities besides a competitive rental yield potential. While there is no single formula, successful properties tend to share common features. These can include a desirable location with strong rental demand, good transport links and local amenities. A buy to let new build can align with many of these factors, particularly in growing areas where demand for modern housing is high.”
