HOA docs are $200 to $500 here and no one wants to pay in advance until they know they have a firm contract. They also need to be current so if you order them and some time passes before the transaction is set to close they may have to be re-ordered for additional expense. If you want them in advance as a buyer you most likely will have to pay for them yourself. Where CA is different is the protections for the buyer are likely unparalleled across the country. Deposits are more refundable here than anywhere else I have ever heard. Once in escrow you can review the docs and if you dont like what you see you can cancel and get 100% of your deposit back. Simple as that.
You seem to be one of those buyers I run into from time to time who think they know it all and are smarter than any real estate agent so I wont bother to tell you anything more. You already know it all.
