go to zillow and realtor.com. dont go off of there zestimate but you can use these sites to show you houses in the area that are for sale and that have also already been sold. this can be a great way to guide you in finding comps for the market you are interested in learning.
I am to from a poor family, went to college got a good job and am now right at the brink of shoving into this business by saving every dollar i can and making sacrifices you wouldnt believe. Just because you come from poverty does not mean thats where your heading. Keep your credit score good and start building on it because a good credit score is key to have if your looking to jump into real estate. IF your credit is not good THATS NOT A BIG DEAL. get a free credit report from the government site that offers one free report a year NOT CREDIT KARMA OR THOSE OTHER SITES.
GOOD LUCK BUD.
i think its awesome that your so young and are already looking to build a solid foundation for your future!
