Preparing a real estate purchase project is not just about visiting properties and signing a preliminary agreement. The current context, marked by a relative easing of rates but still tight banking criteria, requires a rigorous structuring of the file well before the first search. Here, we detail the points of vigilance that most consumer guides overlook.
Effort rate and remaining living expenses: two indicators that banks scrutinize before assessing borrowing capacity
Calculating borrowing capacity based solely on income is a common mistake. Lenders first analyze the actual effort rate in relation to remaining living expenses, not just the debt-to-gross-income ratio.
In practice, a household with a comfortable net income but high recurring expenses (alimony, ongoing consumer loans, residual rents) will see their file rejected even below the usual threshold. The average effort rate observed on accepted files hovers around 30%, with long durations remaining the norm to keep monthly payments manageable.
We recommend paying off any consumer loans before submitting a file. An early buyback, even with a penalty, mechanically improves the debt ratio and signals to the bank a well-managed financial situation.

Since autumn 2024, average rates have begun a significant decline, dropping from around 4.20% to about 3.30% in January 2025 according to data from Observatoire Crédit Logement/CSA. This decrease has mechanically revived financing requests, but the granting criteria remain cautious. The window of opportunity is real, provided the file is impeccable.
Structuring the financing file: what makes the difference in the credit committee
A banking file is not limited to the last three pay slips. The credit committee evaluates the overall coherence of the borrower’s profile over several months.
- Stability of income over 12 to 24 months: bank statements should show neither recurring overdrafts, nor payment incidents, nor unexplained balance fluctuations
- Residual savings after contribution: keeping the equivalent of three to six months of payments reassures the lender about the ability to absorb an unexpected event
- Coherence between the project and the profile: a first-time buyer targeting a property representing more than six years of net income triggers a reinforced examination of the file
- Absence of a risky co-borrower: if one of the two profiles has a precarious contract or a fragile banking history, the file is analyzed based on the weakest profile
First-time buyers, who today account for the majority of the recovery in transactions, are particularly exposed to these filters. Less experienced, they often underestimate the importance of impeccable account management in the six months preceding the application.
The role of the broker in optimizing the file
Engaging a broker is not just about negotiating the rate. Their primary utility is to pre-qualify the file according to the internal grids of each partner bank. Each institution applies different weightings on remaining living expenses, type of employment contract, or property location.
An experienced broker will direct the file to the bank whose criteria best match the profile, reducing the risk of refusal and speeding up the release of funds.
Preliminary sales agreement: the suspensive clauses not to be overlooked
Signing the preliminary agreement is the moment when the buyer legally commits their responsibility. Suspensive clauses constitute the only legal safety net in case of a blockage.
The loan approval clause remains the most critical. It must mention an amount, a maximum rate, and a duration consistent with the actual financing plan. Setting a ceiling rate too low (out of excessive caution) can paradoxically backfire on the buyer if no bank offers that rate: the clause applies, but the seller may contest the good faith of the approach.
Beyond financing, two clauses deserve particular attention:
- The suspensive clause related to obtaining a building permit or urban planning authorization, if the project involves structural work
- The clause for the sale of an existing property, which secures the buyer-seller but extends deadlines and weakens the offer against a competitor without conditions
We observe that buyers often forget to have the preliminary agreement reviewed by a notary independent of the seller. The seller’s notary drafts the deed, but nothing prevents the buyer from appointing their own to check the easements, mortgage status, and technical diagnostics. Fees are shared between the two notaries without additional cost to the buyer.
Overall acquisition budget: the items that online simulators ignore
Online calculators display a monthly payment amount. They almost never take into account all the additional costs that weigh on the actual budget.
Notary fees (transfer duties, fees, disbursements) represent a significant part of the total cost in the old market. Added to this are the loan guarantee (mortgage or bank guarantee), borrower insurance, any brokerage fees, and compliance work if the energy diagnosis reveals a thermal sieve.
A realistic acquisition budget systematically includes a margin of 10 to 15% beyond the displayed price of the property. Without this margin, the financing plan finds itself under pressure from the first months, increasing the risk of default or forced resale.
The current market, driven by first-time buyers but still fragile, does not forgive tight financial arrangements. Structuring the project in advance, with a solid banking file and a clear vision of actual costs, remains the best protection against unpleasant surprises after signing.
