Ok, so my thoughts to your points.
1. Utilities are the renters responsibility so don't factor that in.
2. As far as insurance goes, external parts may be covered by the assoc. unless your tenant burns the place down, or some other problem originates in the unit they own. So in addition to their renters insurance, you'll need to get insurance as well - don't guess, get a quote, should only take a few minutes but I'm betting it will be more than $50.
3. All those items (and associated %) are taken from your gross rent. Being conservative you should plan for 2-3 months of vacancy initially so you can get your rehab done then plan for 6% from then on (6% of 1800 = $108). CapEx/Maintenance can be lumped together to include any and all repairs/issues that you may need to address, again as a % of gross rent, peoples number for this varies, but let's say since it's a condo it will be lower, so we can use 15%, which is $270.
So take your 1800 rent minus your PITI (1358), vacancy (108), and CapEx (270) gives you a cash flow of $64, before any insurance numbers which I again bet is going to be more than $50/mo. I would pass, I personally hate HOA's and avoid them like the plauge.
If you're not sure how to analyze and understand the numbers of a rental, do some more research here before buying anything and getting underwater.
