The price displayed on a real estate listing represents only a part of the actual budget. Between taxes paid to local authorities, banking fees, and expenses related to the condition of the property, the gap between the sale price and the final cost of the transaction can reach several tens of thousands of euros. Anticipating these items helps avoid an undersized financing plan.
Transfer taxes: the 2025 increase changes the game depending on the departments
General articles often mention a notary fee rate between 7 and 8% for older properties. This benchmark remains valid in terms of magnitude, but it masks a recent evolution. Since the 2025 finance law, most departmental councils have raised their rates for transfer taxes (DMTO).
A large majority of departments now apply a full rate of about 6.32% for DMTO, compared to about 5.81% in those that have remained at the old scale. On a property priced at 300,000 euros, the difference between these two rates represents over 1,500 euros in additional taxes.
First-time buyers purchasing their primary residence benefit from an exemption from the 0.5-point increase. Their DMTO remains capped at a lower level, creating a concrete cost gap depending on the buyer’s profile. Before signing a preliminary agreement, checking the rate applied in the relevant department is a reflex to adopt, as not all territories have exercised this option in the same way. To better understand the costs to anticipate on Capitaine Immo, it may be useful to consult detailed simulations by department.
In addition to these transfer taxes, there are notary fees (a proportional rate regulated by decree, thus non-negotiable) and disbursements, which are the administrative costs advanced by the firm. In new builds or VEFA, notary fees fall between 2 and 3% of the property price, as transfer taxes are replaced by VAT already included in the sale price.
Actual cost of mortgage credit: beyond the nominal rate
The interest rate displayed by the bank is not enough to evaluate the cost of financing. Several lines of expenses are added, and some are negotiable while others are not.
Bank processing fees
The bank charges processing fees when setting up the loan. The amount varies by institution, generally between a few hundred and a thousand euros. This is one of the few items where direct negotiation is possible, especially when the borrower presents a good risk profile.
Borrower insurance
Borrower insurance can weigh as heavily as the interest itself over the total duration of the loan. The Lemoine law allows changing insurance at any time, which opens up real maneuvering room to reduce the overall cost. Comparing delegation insurance offers before signing remains one of the most effective levers.
Loan guarantee fees
The bank requires a guarantee on the financed property. Three formulas coexist:
- The conventional mortgage, which involves a notarial deed and fees proportional to the amount borrowed, plus release fees in case of early resale.
- The lender’s privilege (or registration in real estate privilege), slightly less expensive than the mortgage as it is exempt from the property publicity tax.
- The guarantee by a specialized organization (like Crédit Logement), often the cheapest solution, with part of the fees refunded at the end of the loan.
The choice of guarantee has a direct impact on the total cost of credit, and the bank does not always offer the most advantageous formula for the borrower.
Energy audit and DPE: an indirect cost that weighs on negotiation
The Climate and Resilience law has established a regulatory obligation for energy audits for the sale of properties classified F or G in the DPE. This obligation is gradually extending to class E. The audit, distinct from the simple DPE, details renovation work scenarios with their estimated costs.
For the buyer, this document becomes a negotiation tool. A property classified F or G with an audit estimating heavy work (insulation, replacement of the heating system) is negotiated with a discount. The displayed price rarely includes the actual cost of bringing it up to energy standards.
Field feedback varies on the extent of this discount. In some tight areas, the impact on price remains moderate. In more relaxed markets, the discount can become significant. Reading the energy audit before making an offer, and not after, allows budgeting for the work as a separate acquisition item.
Real estate agency fees: who pays and how much
The agency commission generally represents between 3 and 10% of the sale price. This percentage varies depending on the property’s location, its price, and the agency’s practices. The sales mandate specifies whether the fees are the responsibility of the seller or the buyer.
This distinction is not just a formality. When agency fees are the responsibility of the buyer, they are added to the net seller price but the transfer taxes are calculated on the price excluding commission. The taxable base is therefore lower, which slightly reduces notary fees. Conversely, when the fees are the responsibility of the seller, the displayed sale price already includes the commission, and the DMTO applies to the total.
Checking the distribution of fees in the mandate allows for a more accurate overall calculation. This detail, on a high-priced property, represents several hundred euros of difference in notary fees.
Property tax and condominium charges: recurring costs forgotten in the budget
The property tax is not an acquisition cost in the strict sense, but it impacts repayment capacity from the first year. Its amount depends on the cadastral rental value and the rate voted by the municipality. The differences between neighboring municipalities can be considerable.
For a purchase in a condominium, the amount of quarterly or monthly charges (maintenance of common areas, building insurance, mandatory work fund) must be included in the monthly budget. The seller is required to provide the minutes of the general assembly and the maintenance log: these documents reveal the voted or upcoming works, thus the foreseeable calls for funds.
The sum of the property tax and condominium charges constitutes an annual cost that modifies the real effort rate well beyond the monthly loan payment. Ignoring it when calibrating the purchase offer is to underestimate the holding budget of the property in the early years.
