Dealing with limited info on property ads

[Matt Crain]

Hi everyone greetings! My name is Matt I'm a complete newbie, I decided to learn how to tackle property analysis first and foremost, I feel like that is something that is critical to know. However I'm trying to use the calculators and a lot of the info it asks for I cannot find on the ads ( I'm using Zillow and Realtor.com sites ) Is this something I need to contact the agent or owner about? And if so how do I know I'm getting accurate information? Also are there other things I should learn before this? Is property analysis a good starting point? Thanks everyone in advance!
