During meetings clients may share books and records and ask my opinion of value for a specific property. My answer is "I'd much rather take the time and effort to prepare a valuation". In which case I would re-tour the property and area around it, compile rental and sale comparables, underwrite the financials with a fine tooth comb, provide a SWOTs analysis, and then deliver the valuation at a follow-up in-person meeting. This analysis may take 4-6 hours but builds trust and provides accuracy.
