How do you estimate homeowners insurance cost?

[Teresa Phillips]

This is the first time I have posted here so I’m not sure if I’m doing it correctly but I have a question. I am currently saving and studying and hope to purchase my first property in the spring. I am relatively certain I would like to do a house hack with a duplex or triplex. One of the books that I read said as part of my education I should practice underwriting properties to determine cash flow to learn if the property is a good deal. I understand that one part of the cash flow equation is the cost of homeowners insurance. How do I estimate this cost when looking at a property online? If I were actually purchasing these properties I would get this information from my insurance company but since I’m just practicing I wonder if there is an equation to get a ballpark idea. I currently live in a condo so I have never actually had a homeowners policy for a regular home.
