Property Merchant Business in 2026: The End of Guesswork
In a context of interest rates stabilized around 3.5% - 4% and increasingly strict thermal regulations, the modern property merchant can no longer rely on approximations. The success of a buy-and-sell operation now rests on surgical mastery of three variables: thermal sieve renovation costs, applicable VAT regime, and final green value.
Why Use Dedicated Margin Calculation Software?
In 2026, a €15,000 error on external insulation or misinterpretation of margin VAT can transform a lucrative operation into a total loss. Our tool integrates the latest tax developments and real post-inflation material costs to give you an immediate verdict.
The 3 Pillars of Property Merchant Profitability in 2026
1. Mastery of Margin VAT
The margin VAT regime remains the most complex. As a reminder, if you buy from a private individual (non-registered) and resell after works, the 20% VAT only applies to the difference between resale price and purchase price. However, if the property's nature changes (office to residential conversion), the regime may shift. Our simulator integrates these specificities to avoid surprises at the end of operations.
2. Impact of EPC on Resale
A property merchant who buys a G-rated sieve to resell a G-rated sieve takes a massive liquidity risk. In 2026, final buyers demand a minimum D-rated EPC to obtain their mortgage. Your renovation budget must imperatively include the "Sieve Exit Pack" to guarantee a quick and profitable resale.
3. Reduced Notary Fees (Merchant Regime)
One of the major profitability levers is the application of reduced notary fees (approximately 2% to 3% versus 7.5% for individuals). Note: this privilege is conditioned on resale within 5 years. Our tool automatically calculates this saving to refine your working capital requirement (WCR).

Can you recover VAT on renovation works?
Yes, if you're VAT-registered, you can recover VAT on your contractor invoices. This is an important cash flow lever to integrate into your financing plan.
