newbie here with 2 queations

Hello I am very new to real estate investing. And by very new I mean this has been the first week I have ever looked into real estate investment. My first question is I have looked on Redfin and Zillow and seeing some house that look like they could have possibility to flip for decent profit. But I noticed that some of these have been listed for quite some time. What are some reasons that other investors have overlooked this property besides obvious things like major repairs?

My next question is what percent would you give someone who is only co-signing a property for you?

If you're only going by pictures/info on zillow you're only getting about 33% of the story.  If you've gone out and seen the properties and still have this question you might be missing things that a more seasoned person might catch like electrical issues, rodent infestations, foundation problems etc.. Or it could just mean you're willing to do more work than the typical investor.  Most important thing for you is to get a knowledgeable agent's opinion on comps in the area you're looking.
