The quick answer is, well, it depends.
The types and number of accounts you have on your report can make this worthwhile....or, not. Example, many people have heard of things like Self-Lender, where you're basically making payments to yourself in exchange for positive credit history being reported. But if you have an installment loan already on your credit in good standing, the net effect from a Self Lender account won't be as great. BTW, I am currently using Self Lender myself and it has helped.
It also depends on other factors too, like average age of credit on your report. If you have long-standing credit showing up and it's positive, reporting rent probably won't help you so much. Another issue to consider is the cost. Companies that report your rent to your credit are not doing it for free. Cannot remember the name of it now, but one such place was discussed in here not too long back and the cost just seemed too high to make sense to me. Also, some apartment complexes are already doing this. I know a place here locally that will report your positive payment history for $5 a month, which is nothing when you're trying to rebuild.
Best suggestion I could give is make sure you check out whatever company youre considering going with before you sign up. And shop around, you might just find a less costly alternative.
