“Please understand that by law I am not able to provide you with any documents that my tenants personal private protected information is on, but at closing you will receive the files”Is this true?

I'm not able to purchase with all cash here because of the higher prices and I do not invest in D neighborhoods.

If you're not able to before then definitely once you're under option/escrow. 

Examples of situations in which this becomes relevant is acquisitions of properties that were previously vacant, owner occupied, or utilized as long-term rentals, or refinances post-rehab (commonly known as “Air BnBRRRRs”).If there are no historical STR bookings available, if the lender is not able to use Air DNA projections, they may be forced to rely on the 1007 market rent qualify the DSCR ratio, and thus the property might not cashflow (market rent will not equate or exceed monthly PITI).

I have been a longtime lurker of BP (since 2011) and have seen very active people not post anymore for various reasons.Some of the big real estate players are in masterminds with other real estate giants.

I keep asking myself even if I wanted to sell, what the heck would I do with a giant pile of money that begins losing value to inflation before I walk out of the closing. 

They can share contacts for all the various contractors/labor they use who will give you the best prices.So, anywhere you see a house being rehabbed, stop and talk to the person who is rehabbing.If you're not able to make contacts that way, go to your local builder's supply store, make friends with the guys/gals who work at the pro desk. 

Also, I  used to be stationed in San Diego CA, so I am not able to hate, because I understand the love for Cali. 

You can contact the city or district and they may negotiate to lower or settle remaining taxes say for 10 to 12 thou cash and offer seller 5 thousand and his headache goes away he is obviously in trouble and not able to afford and will be losing the house really shortly try to make this a win win situation for everyone 

I am a little puzzled that you're not able to get a fully amortizing 15 year fixed rate.
