The Bank´s Valuation Came in Low: How to Prepare a "Technical Complaint" and Save the Business A low bank valuation doesn´t have to be the end of a deal; at Royal House, it´s the start of a well-founded technical challenge. Unlike common resignation, we use "Claim Engineering" to confront the Comparative Method with real data, precise metric corrections, and the proper valuation of improvements invisible to the... 11 May 2026 min de leitura The buyer is there, the price is agreed upon, but the bank appraiser valued the house R$20,000 below market value. The loan doesn't cover the purchase. The deal is at risk. Most sellers give up or lower the price. At Royal House, we technically contest this. The Claims Engineering: Experts use the Market Comparison Method. If the appraisal was low, it's usually because the appraiser used incorrect "comparables" (houses sold at lower prices or in worse condition). We prepare a Contestation Dossier: Evidence of actual sales: We provide deeds to neighboring properties recently sold at higher prices (data the appraiser may not have). Area Correction: We prove if the appraiser forgot to include the habitable attic or garage as usable area. Recovery of Improvements: We technically list the value of thermal insulation, home automation, and premium materials that are not visible in a quick 15-minute visit. We don't accept "no" from the bank's algorithm. We fight for the value of your home using financial engineering arguments. Share article FacebookXPinterestWhatsAppCopiar link Link copiado
