The Asking price has NO bearing or relation what value the bank may accept. That price was set be the owner/agent.....the lender doesn’t even know it is for sale. The only value/number that matters is the BPO the lender comes up with After they have reviewed the paperwork and contract submitted.
As i@Charlie MacPherson’s example demonstrates......you, the listing agent should have already if they are competent, need to run title to see if there are 2 mtgs, other liens, etc.
This is the only way to project how much, if any, the buyer may need to come up with in Addition to the purchase price, and structure your offer accordingly. I had many buyers prepared and agreed to kicking in $10k or more in addition to the purchase price, and lowered their offer price accordingly.
