Banks always want to sell a property in as is condition. Most will provide a Section 1 pest certification, but not unless you include it in your offer and negotiate the point. They will allow you to get all the inspections you want (at your expense), but they may not agree to do any repairs.
Your offer should include an inspection contingency period that allows you to terminate the sale if the inspections reveal unanticipated damages that the bank will not correct.
Even though you agreed to as is, always give the bank another opportunity to make repairs or give you a credit after youve completed your inspections. Sometimes theyll re-negotiate to save the transaction instead of putting the property back on the market, but dont take it for granted.
Banks do not want to see a lot of proprietary disclosures; they are exempt from the California Sellers Transfer Disclosure Statement (TDS-14). If there are real estate agents involved, either representing you or the bank, those agents are required to provide you their disclosure statements.
