Investing in beach condo. Need advise on expected costs

[Thomas Moss]

Current have 1 single family home LTR. Looking into getting into a beach condo possibly in the Florida panhandle. 

I have very little knowledge regarding the costs accompanied by this and therefore difficult to calculate deals/cash flow when assessing properties. 

Would anyone be able to give rough estimates of electric/heat/air bill. Also unsure of insurance costs. 

Any blogs, podcast episodes, books, any links to read up on would be greatly appreciated.
