Estimating Insurance costs in Tampa FL when evaluating deals

[Dylan Hanna]

Does anybody have a rule of thumb price or percentage for estimating insurance costs based off home value/home size  when evaluating deals for a multifamily property? Is there even a way to get in the ballpark for this estimate with out reaching out to an insurance agent each time I want to evaluate a deal? I understand that there are many other factors than size and price and that I need to call an insurance agent to get a quote for an accurate evaluation, however, I am attempting to quickly analyze many deals daily. Thanks!
