I'm glad you are here! There are two ways you can go about finding "trash-out" business for REO properties. You can choose one or do both.
1. Passive- Register as a vendor through many of the banks websites. You can search this information online usually falls under the terms "property preservation". Once you are registered, the agents who list these properties are sometimes required to use a list of approved vendors. Get ready to spend some serious time filling out applications online! The work might come, it might not.
2. Active- Get in front of the agents who are listing these properties. Keep in mind these agents are very busy people. You will have one shot if any to make your mark. So be ready to offer services, have numbers ready, prove the added value of your service as opposed to the company they have been using for years. I think your best bet would be to start hunting squirrels rather than buffalo. Find someone who may have a few properties and is actively working to acquire more REO listings and grow with them.
I hope this was some help for you, if you do need further assistance drop me a line. How long have you been in the business? have you tried either of these approaches yet?
Jeremy gave you a great answer, and very thorough. I will second his suggestion that you contact listing agents. Once you have a few that will give you references, it is much easier to get more work. If you are reliable and honest word will get out. I used to get most of my vendors from other agents who had had positive experiences with someone.
Best of luck.
