To some degree that depends on who you are going to market your services to. Assuming banks and realtors that is a difficult barrier to break into. Many of those folks have their favorites that they like to use. You aren't exactly getting in on the front end of this work. Can you answer why they should use you instead of their existing company?
Another very important and overlooked consideration is where are you going to do this work. In the City or the Burbs. Many of the foreclosures in the City are in rough neighborhoods. If in the City are you capable of handling yourself in an urban environment, Do you have a vehicle that doesn't scream 'target', can you handle roaches, rats and the occasional flea infestation, are you comfortable making police contacts, do you know not to run when that dog is looking at you like it's next meal, do you know what colors not to wear, can you interact with people without coming off like a snob, do you know not to stare at the guys standing on the street corner?
You won't be able to just 'send your laborers' out to every site and stay home. You will have to go out to some properties. The questions may seem a bit rough but the answers will keep you safe. Dogs, guns, violence and sickness are all potential hazards. Not trying to dissuade you, just pointing out a few things.
Good luck... more
