Introduction

Borrowing 100,000 euros to buy a property in Massy, Palaiseau, or Chilly-Mazarin raises the crucial question of the ideal monthly payment. As of today, the payment ranges between 525 € and 1,024 € depending on the term and 2025 market conditions. For 25 years, expect about €582/month; for 20 years, €652; for 15 years, €780. The right duration is the key to managing your budget and making your property purchase a reality in the best conditions.

Calculating payments according to loan duration

100,000 euro loan over 25 years: maximum accessibility

For 25 years, the monthly payment is around €582. This solution offers flexibility and accessibility, perfect for a first purchase in Massy or Palaiseau. A minimum salary of €1,663 net is needed to respect lending criteria, making a real estate project possible with even a modest down payment. For every project, Nicolas Immobilier delivers personal guidance and precise simulations using its free property valuation tool.

100,000 euro loan over 20 years: balanced and controlled budget

The monthly payment is about €652 over 20 years. This duration attracts working couples who want to invest in a strong local market, where average prices per square meter in Massy are around €4,028. An income of €1,863 net minimum is required for this scenario. By working with Nicolas Immobilier, you benefit from a complete assessment and customized support.

100,000 euro loan over 15 years: quick payoff

100,000 euro loan over 10 years: minimal costs, higher payments

A 10-year loan results in a monthly payment of €1,024. This requires a substantial income (at least €2,926 net) but greatly reduces the amount of interest paid. It's ideal for seasoned investors or those with significant savings.

Key factors shaping your loan payment

Interest rate and bank negotiation

The rate strongly impacts the total cost. In 2025, average mortgage rates remain below 4.5%. Nicolas Immobilier emphasizes the power of negotiation, leveraging local banking partnerships to obtain the best terms.

Down payment: balancing factor

A significant down payment lowers the amount borrowed—meaning lower monthly payments. For instance, with €20,000 down, the monthly payment over 25 years would drop to €466. Try a free property valuation to refine your financing plan.

Borrower insurance: don't overlook it

Insurance (about €28/month for €100,000 borrowed) should be part of your budget. The Nicolas Immobilier team will help you choose the best insurance option to keep your overall payment manageable.
