Private landlord: 5 measures that boost rental investment in Haute-Savoie

The parliamentary report submitted to Valérie Létard proposes five major levers to encourage rental investment. A focus on their concrete effects in our valleys and on the shores of the Alpine lakes.


1️⃣ Enhanced amortisation for new and old properties: a major lever forrental investment

Amortise 5% on new build

From acquisition, the private landlord will be able to deduct 5% per year from the cost price of the new dwelling. Enough to smooth the financial effort while securing profitability, particularly for recent developments around Lake Annecy.

4% + 15% of works on old properties

In village centres or ski resorts, many properties require energy renovation. Amortisation of 4% per year, combined with the possibility of deducting 15% of works from the first year, boosts cash flow and speeds up compliance with the 2028 standards.

2025 trend : demand for homes rated A or B jumps by 28% in Savoie-Mont-Blanc. Investors who anticipate renovation are already capturing this growing green value.

2️⃣ Affordable rents & property deficit ceiling raised to €40,000: heading for an affordable rent

Tax bonus of 0.5% to 1.5%

By letting below market rents, the landlord obtains additional amortisation. A winning strategy to retain local families while securing a net return.

Property deficit doubled

The ceiling rises from €21,400 to €40,000: a significant boost to absorb insulation works or the installation of heat pumps, very common in our altitude chalets.

This measure strengthens the attractiveness of mid-mountain communes, where vacancy has already been falling since the end of 2024.


3️⃣ Exit from IFI and holding period reduced to 20 years: advantages for landlord owner in the mountains

Exclusion from IFI during the rental period

Eligible dwellings let on a long-term basis (minimum 9 years) are removed from the IFI (real estate wealth tax) base. For estates worth more than €1.3m, it is the certainty of maintaining regular net income.

Reduced capital gains tax after 20 years

The holding period for full exemption falls from 30 to 20 years. In a Haute-Savoie market where values are still rising (+4.1% over one year), this relief offers welcome flexibility for adjusting your portfolio.


4️⃣ Macro-economic impact & local expertise : how Althenor guides you with a personalised advice

+ 90,000 homes/year and + 100,000 jobs by 2030

These national objectives will translate locally into targeted projects: rehabilitation of large chalets, micro-developments around Lake Geneva, and natural eco-neighbourhoods near the resorts.
