New-build or existing property: which is the better investment?

By Loro Real Estate team · Last updated: July 2026

New build or existing property? Few questions occupy private investors more before their first or next property purchase. Some favour new-build predictability and efficiency; others the lower price and established location of existing apartments. This guide compares strengths and weaknesses, depreciation and yield, maintenance and lettability. It does not crown a universal winner — none exists — but provides a reliable basis for your decision.

First, property is a long-term investment with opportunities and risks. Rental default, interest changes, value fluctuations and limited liquidity affect both types. Check all tax information against current rules, as laws and rates can change.

The starting point: both approaches can work

“New build versus existing” is often treated as a statement of principle. In practice it is a calculation. Both can be investments or mistakes. Viability depends not on category, but on the full individual assessment: price and purchase costs, achievable rent, non-recoverable expenses, maintenance needs, tax effects and financing terms.

A structured comparison therefore helps: knowing typical strengths and weaknesses lets you ask the right questions and spot optimistic arithmetic versus a sound calculation.

New builds as investments: strengths and weaknesses

Strengths of new builds

• Energy efficiency. New builds meet current energy standards. This means comparatively low consumption costs for tenants and no foreseeable pressure to renovate for energy requirements.
• Low maintenance in the early years. Systems, roofs and façades are new, backed by warranty claims against the developer. Early years are therefore predictable.
• Tax depreciation. Residential buildings completed from 2023 receive 3% annual straight-line depreciation. Construction begun between 1 October 2023 and 30 September 2029 permits 5% declining-balance depreciation on residual value with a later switch to straight-line. Under conditions including Efficiency House 40/QNG criteria and construction cost caps, section 7b special depreciation of up to 5% annually in the first four years may apply too. See our guide to Property depreciation (AfA) — please check the current rules.
• Good lettability. Modern layouts, up-to-date fittings and low service charges appeal to many tenants. In high-demand regions, new apartments generally let quickly.

Weaknesses of new builds

• Higher price per square metre. New condition, current standards and construction costs have a price; entry usually costs more than comparable existing properties.
• Often lower initial yield. Achievable rent does not rise proportionally with price, so initial rental yield is often lower than for existing property.
• Completion and project risk. Buying from a developer generates rent only after completion. Allow realistically for delays and project risk, and check the counterparty carefully.

Existing property as an investment: strengths and weaknesses

Strengths of existing property

• Lower entry price. Existing property usually costs less per square metre, reducing capital required or widening your choice within the same budget.
• Established location. Mature infrastructure, known rents, an assessable neighbourhood: you buy what you see and judge the location using real data rather than forecasts.
• Immediate rental income. Buying an already Buys a tenanted apartmentprovides income from transfer, with the tenancy and tenant's payment history known before purchase.

Weaknesses of existing property

• Maintenance and renovation risk. Roofs, heating, pipes and façades age. Check actual condition, meeting minutes and owners' association reserves carefully before buying or risk unplanned expenses.
• Energy requirements. Age and renovation status may require energy investment. Energy condition must therefore be included in every purchase review and calculation.
• Lower depreciation. Existing buildings generally receive 2% straight-line depreciation if built from 1925, or 2.5% if built before 1925, lower annual rates than new builds.

Comparison across six criteria

Here is how the two types compare on key decision criteria:

• Price: existing property is usually cheaper per square metre; new-build prices include new condition and current standards. What matters is whether price matches location and achievable rent.
• Ongoing yield: existing property often starts with higher rental yield; new builds often lower, offset by lower early maintenance costs.
• Tax and depreciation: new builds offer higher deductions through 3% straight-line depreciation for completion from 2023, optional declining-balance depreciation and potentially section 7b; existing properties usually offer 2%. Tax is part of the calculation, never the main motive, and current rules must be checked.
• Maintenance: new builds start low and benefit from warranties; existing property involves real costs requiring reserves and buffers. Both need honest long-term maintenance planning.
• Energy efficiency: new builds meet current standards; existing property depends on renovation status. An energy-efficient existing property can be attractive; one needing upgrades requires an appropriate discount.
• Lettability: both let well in high-demand locations. New builds appeal through fittings and service charges, existing property through established location and often more moderate rent.

What really matters

The honest answer: location, condition and price beat category. An overpriced new build in a weak location is not a good investment; a carefully checked existing apartment at a realistic price can be. Conversely, a fairly priced new build in a strong-demand area may offset lower initial yield through predictability and low early costs. Looking only at the label asks the second-most-important question first. Compare both with your own figures directly in the interactive rental yield calculator.

This is how Loro Real Estate works: on the buyer side, with curated, vetted properties of both types across Rhein-Neckar and Hessen, commission-free for buyers and with off-market access. Since 2018 we have supported over 250 clients and manage more than 1000 units. See current properties in our overview of current projects.

Conclusion: no universal winner, but a clear decision process

There is no universal winner. New builds tend to suit investors who value predictability and low initial maintenance, can use higher depreciation and accept lower initial yield and completion risk. Existing property tends to suit those favouring lower entry cost, established location and immediate income, who will actively manage condition checks, reserves and potential renovation.
