When to ask for P&L, tenant ledgers, etc.

[Anthony Vaudo]

Hello,

I am looking at a mixed use property on Long Island (first floor retail plus 4 residential above) and would like to know when the most appropriate time is to ask for things like audited financial statements, tenant ledgers and/or anything I else I should be asking for?  Is it (a) pre-offer (b) after an accepted offer but before contract signing (c) after contract signing during a due diligence period?  I just want to make sure that I am able to fully validate all of the financials and not on the hook/forfeit my deposit if the numbers do not match what's being advertised.  Also do not want to scare away the seller.  Thank you!
