The easiest way is to do 571 jobs for Real Estate Brokers in your area. 571 repairs are small, emergency repairs that don't require the contractor to be SAM certified. Become reliable to a few brokers adn they can sponsor you. There are other things you need to know, but there isn't enough space on this answering box to go over all of them. Things such as pricing and specs required by Fannie Mae. Start with 571s though. Hope this helps.
