VC137FE, I started out as you did with 0 hours in the Commander and 140 hours of total time with only a PPL a few years ago and my insurance started at $1,300 annually. The insurance had a 25 hour dual instruction requirement in the aircraft (of course I purchased the aircraft and got my 25 hours in my aircraft with an instructor who was qualified in the AC11 as well, that is acceptable to most insurances). That was in October 2017. Today I am paying $1,503 annually for $100K haul value and I have over 800 hours in the commander now with commercial certificate and instrument add on.
As for the annual cost, depending on the amount you borrow and where you hanger your new mistress, here is a my break down of ownership cost:
Monthly Plane Payment (unless you pay outright): $500.00 (depends on interest rate and amount borrowed)
hanger Rent: $250.00 (hanger rent varies on where you are)
Insurance: $126.00 (this is normally paid in a lump sum once a year)
Total monthly out of pocket expense (no fuel or maintenance): $876.00
I normally put back $35.00 for every hour I fly for maintenance and engine repairs.
This is all going to vary depending on your situation, but these are real numbers from my experience. I can tell you that I have sunk over $67K in the plane since October 2017 in a top engine overhaul, new JPI, new interior, new hydraulic power pack, new Aspen, auto pilot rebuild, and tons of other misc. components for my engine.
Every penny has been worth it that I have spent on the plane. The plane is a very comfortable platform for cross country's and I have even tried making my self sell it and upgrade to a twin but my family say's no, they enjoy the Commander to much. Hope this helps and hope you find a Commander to enjoy.
