Analyzing an Investment Property but Missing Important Data

[Ayodeji Kuponiyi]

Cash Flow is important to me. I'm trying to figure out how to properly analyze a property but I find my big road block are: knowing the insurance price, all tax information (such as: school, property, borough/county) and mortgage payments (it seems I have to first get approved to know this). 

• It seems I have to contact insurance companies to get a quote but isn't there a way to get this information on the web with comparable prices?
• Where can I find a property tax information that shows all the taxes for a property?
• To determine mortgage payments, should I call a bank to find out what I'm approved of first and then bring up a property I'm interested in?

To analyze a deal it seems I have to reach out to get accurate or close estimates to know what I'm dealing with to determine if it's positive cash flow or negative.

Any suggestions or advice?
