New-build or Existing for Investment: How to Choose in 2026
Published on October 19, 2026 · New vs existing
Are you torn between a new-build home and an older property for your buy-to-let project? It is one of the most frequent questions we receive at JL HOME. The answer depends on your situation, your wealth-building objectives and your holding horizon. In this article, updated for 2026, we compare the two options point by point, without marketing shortcuts, to help you decide with full knowledge of the facts.
Understanding the fundamental differences between new and older homes
Before discussing figures, let us set the scene. A new-build home is a property never previously occupied, delivered by a developer and often sold under VEFA (vente en l'état futur d'achèvement, off-plan sale). An older home is an already-built property, sometimes in need of renovation, bought on the resale market.
These two markets do not follow the same logic. New-build emphasises energy performance, builder warranties and reduced acquisition costs. Older homes appeal through their central location, their character and a purchase price that is sometimes lower per square metre. Each has its strengths and constraints: the right choice is the one that matches your profile.
Acquisition costs: a notable gap
A first concrete point of comparison: notary fees. For new-build, they are reduced, of the order of 2 to 3 % of the property price. For older homes, they are generally around 7 to 8 %. On the same budget, this gap can represent several thousand euros.
In addition, in certain cases and under conditions, a reduced VAT rate of 5,5 % applies to the purchase of a new-build home located in specific zones. Please note: this reduced VAT rate is in no way automatic; it depends on strict criteria linked to location and the property's use. A JL HOME adviser can check with you whether your project falls within this framework.
Taxation: different levers
Existing homes: the property deficit
Existing homes, especially those requiring work, allow use of the property deficit mechanism. Deductible charges and works can reduce your property income and, within certain limits, your overall income. The ceiling is 10 700 € per year, raised to 21 400 € for energy renovation. It is an attractive lever for highly taxed taxpayers who intend to renovate.
New-build homes: furnished rentals and current schemes
In both new and existing homes, non-professional furnished rental (LMNP) remains a popular framework. The micro-BIC regime provides an allowance of 50 %, up to a ceiling of 83 600 € for 2026 income (versus 77 700 € for 2025 income), with a non-professional threshold set at 23 000 €. New builds also give access to recent schemes such as intermediate rental housing (LLI) or the Jean-Brun scheme, which relies on depreciation calculated on a base of 80 %.
It is worth clarifying an important point: none of these schemes is a successor to or replacement for the Pinel scheme. They are separate frameworks, each with its own rules. Nor does any of them guarantee a return: an investment's performance depends on many factors, including location, letting management and market changes.
Maintenance and running costs over time
A new home meets the latest construction and insulation standards. On delivery, you benefit from guarantees: the one-year performance guarantee, the two-year guarantee and the ten-year guarantee. In practice, this means little work to plan in the first years and heating costs that are often kept under control thanks to energy performance.
In existing homes, the picture is more nuanced. A characterful property in a good location can be an excellent asset, but you must anticipate works, facade renovation, bringing the property up to standard and a sometimes unfavourable energy performance diagnosis. For several years, energy-inefficient homes have been subject to progressive letting restrictions. A poorly rated older property can therefore become difficult to let without renovation.
Rental appeal
For an investor, the ability to let quickly and sustainably is essential. New builds attract tenants looking for comfort, energy-efficient homes and no works. A well-located existing property, in a town centre, often enjoys strong demand linked to its location.
The sensible approach is therefore not to decide in absolute terms, but to look market by market. A new home in a tight market, close to transport and employment, can offer better rental visibility than an isolated existing property. That is the whole purpose of our work in selecting and comparing programmes.
Financing: the same principles of caution
Whatever your choice, financing follows the same principles. The reference debt-to-income ratio is 35 %. For a first-time buyer, the zero-rate loan (PTZ) can finance part of a new-build purchase, with proportions and ceilings that vary according to your geographical area and income.
JL HOME is a new-build estate agent holding a T card. We are neither a broker nor a credit intermediary: our role is to support you in choosing and reserving the property, and to direct you to financing professionals. Current credit rates and assistance such as that from Action Logement change regularly and must be checked case by case.
So, new build or existing?
If you are looking for reduced acquisition costs, little work, guarantees and access to the most recent schemes, a new build has strong arguments. If you are aiming for a highly sought-after central location, a potentially lower price per square metre, and you are willing to manage works to activate the property deficit, an existing home may suit you.
There is no universal answer: there is the answer suited to your project. That is why we offer a personalised discussion to frame your objectives.

In summary
New builds stand out for reduced costs, guarantees and good energy comfort. Existing homes rely on location and works levers. Both can be good investments: the essential thing is to start from a rigorous, dated analysis suited to the market targeted in 2026.
