So I looked up "orange county credit union rates", and found their FDIC insured savings is 0.05%. When you keep $200,000 at 0.05%, you are receiving about $8/month. If you trust just one online bank with your money, the FDIC insured $200,000 earns 1%/year, or $165/month. Would you switch banks if they give you $150/month to switch? Because.. they do!
I personally like Ally (customer service and high rates), but you can find several online savings offering 1% rates on savings. If you're nervous, try this small step first: deposit $10,850 in an online savings (which is FDIC insured) and $200,000 in your local bank (earning 0.05%). And when you see $200,000 earning $8.33 while the $10,850 earns $9.00 it might convince you. :) Good luck.
