Ummm . . . what???
You've started the business and NOW you want to know if it's profitable?
Kind of backwards, don't you think? What research did you do before starting the business?
Quick answer: It CAN be profitable, if you know what you're doing. Still, this whole cleaning foreclosures business totally mystifies me. And I worked for an association for 8 years that represented janitorial and cleaning companies. I've written books on the subject. (Check Amazon.) And I still don't get it.
There is money to be made in residential cleaning of all types--scheduled cleaning, move-in/move-out cleaning, and foreclosures. But there's more to be made in the other types. Besides, why limit yourself?
Before you do anything else, do research on the business. Try http://www.bscai.org Especially, look at what's there on marketing and bidding. You absolutely need those.
