There are several ways to introduce such evidence. There are also several objections to such evidence. It depends on a variety of factors. Is it an admission against interest? Regularly kept business record? Rather than go over the evidence code, it would be easier for you to contact an attorney and discuss the case with an attorney.
Once you go to court and improperly introduce the evidence, if the judge rules against you, then you will have to start all over again, and your tenants will get another month or two of rent-free living!!
