@Ramon Wilson - It is a hard lesson and a rude way to learn it but I echo what @Chris Lopez and @Account Closed said. There are some dumb buyers and gamblers out there, but a market is not sustained solely by idiots (usually! Although, history has some strong counter-examples).
There is not much return out there for investments in this market, so even though LA real estate doesn't look good to all the gurus on Bigger Pockets, in the real world, it is better than fixed income or dividend paying stocks. To me, this is an important distinction between BP and the real world. BP says that deals should only be bought for zero cash down, and at the price backed into with the 2% rule. As you saw, brokers and sellers don't want to listen to that. They are going to sell to the buyer willing to pay the highest price. Why should the listing agent have to justify the price to you? All he cares about is that someone is willing to pay.
As a personal anecdote, I got into investing in 2009 (great, although inadvertent timing - it was the first time I had available cash). I was focused exclusively on cash flow and while I never saw a 2% deal in any part of LA I was willing to go to, I saw a lot of 1% deals, which seemed pretty good to me! I bought in then, and then again in 2011, focused on cash flow. Looking back, while I did well, I would have probably done 2-3x better if I had foregone the cash flow and bought into nicer areas (Santa Monica, West LA) rather than Koreatown, Hollywood, Mid city, etc.
Since then, I've moved into slightly nicer neighborhoods, and I am very happy for it. The tenants are better and so is the appreciation so far. I'm starting to move out of those better cash flowing buildings and buying properties with numbers that I would have laughed at six years ago - because the initial cash flow is so bad. But, you invest in the building, buy out a few rent controlled tenants, and suddenly it looks a little better. Plus you have a better class of tenants which means fewer issues in my experience.
