Acquiring Accurate Numbers to Analyze Deals

[Jackson Miller]

Hey guys! After listening to the podcast and reading as many books as I can get my hands on, I'm taking Brandon and Josh's advice (which is always awesome coming from them) to analyze deals in my area to get a sense of the market and what constitutes as a great deal. 

However, when I look at properties on sale there usually isn't enough information numbers-wise for me to accurately crunch the numbers. Obviously sales price and general info on the property is easily accessible, but I always have trouble calculating monthly expenses and mortgage rates. 

Should I just be calling companies in the area that provide the services I'd be using, as well as a mortgage broker, and get the quotes from them? 

If so, would they even want to talk to me seeing as though I don't have a property yet and am just calling to find out about prices? 

Any advice on how you guys get these numbers yourself would really be appreciated, thanks!
