Expert Report for Exclusive Mandate: Secure Your Mandates with a Technical Audit 2026

Technical Audit Generator for Mandate Unlocking Agent

For professional real estate agents, the technical expertise report is the key tool to secure exclusive mandates and avoid failed sales. By identifying critical defects (cracks, humidity, EPC F/G, asbestos, termites) before listing, you can adjust the price realistically, negotiate works with the seller, and maximize sale probability. A property with 2+ critical defects has a sale probability of <50% and an average delay of 12+ months. A preliminary audit allows reducing this delay to 3-5 months by adapting the strategy.

The 6 Technical Audit Categories for a Secure Mandate

1. Structure (Cracks, Roofing)

Structural defects are the most critical and have the strongest impact on sale:

• Structural cracks: Through cracks, facade lizard, foundation settlement (15,000-80,000€, impact -35% on sale)
• Degraded roofing: Broken tiles, weakened framework, infiltrations (8,000-25,000€, impact -25%)

Recommendation: If structural cracks are present, require geotechnical expertise before mandate or refuse the mandate.

2. Humidity (Rising Damp, Infiltrations)

Humidity is a dealbreaker for 70% of buyers:

• Rising damp: Ascensional humidity, saltpetre, damp walls (5,000-15,000€, impact -20%)
• Water infiltrations: Roof leaks, terrace, exterior walls (3,000-12,000€, impact -18%)

Strategy: Negotiate with the seller to carry out waterproofing works before listing OR adjust the price by -15 to -20%.

3. Energy (EPC F/G - Thermal Sieve)

Since 2023, thermal sieves (EPC F/G) are banned for rental and suffer a strong discount on sale:

• EPC F or G: Defective insulation, obsolete heating (20,000-60,000€, impact -30%)

Legal obligation: Since January 1, 2025, banned to rent an EPC G. EPC F ban in 2028.

4. Safety (Electricity, Plumbing, Asbestos, Termites)

Safety defects are major blocking points for banks and buyers:

• Non-compliant electricity: Obsolete panel, no grounding, fire risk (3,000-8,000€, impact -15%)
• Lead plumbing: Lead pipes, health risk (4,000-12,000€, impact -12%)
• Asbestos present: Mandatory asbestos removal if works (5,000-30,000€, impact -20%)
• Termites or Dry Rot: Wood infestation, urgent treatment (8,000-25,000€, impact -28%)

5. Comfort (Sound Insulation, Ventilation)

Comfort defects impact quality of life and sellability:

• Insufficient sound insulation: Noise nuisance (5,000-15,000€, impact -8%)
• No ventilation: No VMC, condensation, mold (3,000-8,000€, impact -10%)

6. Valorization (Kitchen, Bathroom, Finishes)

Valorization works are optional but significantly improve sellability:

• Obsolete kitchen/bathroom: Old equipment (8,000-20,000€, impact -12%)
• Degraded coatings: Peeling paint, damaged floors (3,000-8,000€, impact -5%)

The 4 Mandate Strategies According to Property Condition

1. Secure Exclusive Mandate (Property Ready for Sale)

Criteria: 0 critical defect, 0-2 important defects, sale probability >75%.
Strategy: Immediate listing at market price. Cosmetic valorization only (home staging, pro photos).
Sale delay: 3-5 months.

2. Conditional Mandate (Light Works Recommended)

Criteria: 0 critical defect, 2-4 important defects, sale probability 65-75%.
Strategy: Negotiate with the seller to carry out priority works before listing OR adjust the price by -10 to -15%.
Sale delay: 5-8 months.

3. Mandate with Suspensive Clause (Major Works Necessary)

Criteria: 1-2 critical defects, sale probability 50-65%.
Strategy: Condition the mandate to carrying out critical works OR sale as-is with significant discount (-20 to -30%).
Sale delay: 8-12 months.

4. Refusal of Mandate (Property Not Sellable As-Is)

Criteria: 3+ critical defects, sale probability <50%.
Strategy: Refuse the mandate OR condition it to completing all critical works. Very high risk of non-sale.
Sale delay: 12+ months (if sale possible).

FAQ: Expert Report for Exclusive Mandate

Why propose a technical expertise report to the seller?

The technical expertise report is a commercial differentiation tool for the real estate agent:

• Secures the exclusive mandate: The seller perceives the agent as an expert who anticipates problems.
• Avoids failed sales: 40% of sales fail due to defects discovered late (diagnostics, buyer visit, bank expertise).
• Adjusts the price realistically: An overvalued property stays on market 12+ months and loses 10-15% of value.
• Increases conversion rate: A well-valued property sells 2x faster (3-5 months vs 8-12 months).

How to calculate the recommended price adjustment?

The price adjustment is calculated using the formula:

Price_Adjustment (%) = Sum(Impact_Defect_i) × 0.5

The 0.5 (50%) coefficient is applied to be conservative and secure the sale. The actual impact of defects is often higher, but too strong an adjustment discourages the seller.

Example: A property with 2 critical defects (EPC G = -30%, Cracks = -35%) has a total impact of -65%. The recommended adjustment is -32.5% (65% × 0.5).

What is the sale probability according to the number of defects?

The sale probability is calculated using the formula:

Sale_Probability (%) = 85 + Sum(Impact_Defect_i)

The base of 85% corresponds to a property in good condition. Each defect reduces this probability.

• 0 defects: Probability 85-95% | Delay 3-5 months
• 1-2 important defects: Probability 65-75% | Delay 5-8 months
• 1 critical defect: Probability 50-65% | Delay 8-12 months
• 2+ critical defects: Probability <50% | Delay 12+ months

What is the ROI of works for the seller?

The ROI of works for the seller is generally 70%:

Value_Increase = Works_Cost × 0.7

This means that for 10,000€ of works, the property gains 7,000€ in value. The seller therefore loses 3,000€ (30%) by carrying out the works.

Advice: It is often more advantageous for the seller to sell as-is with a discount rather than carry out the works, except for critical defects that block the sale (EPC G, structural cracks).
