The questions that you ask are more easily answered with more specific facts (which you should not post publicly, of course). Nonetheless, there is an excellent chance that someone will be indicted after federal law enforcement agents raid a home and seize money and property. Although no drugs were found, a conpiracy charge may be forthcoming if the Government believes that it can prove that the complaints to which you refer have merit. Whether those complaints have merit depend on many different factors, such as who made them and whether they can (or cannot) be substantiated or corroborated. The question regarding whether other real or personal properties will be seized depends on whether the Government can prove, by a preponderance of the evidence, that those properties were the proceeds of a drug offense, facilitated a drug offense, or were purchased or maintained with the proceeds of a drug offense. The question regarding who will be indicted depends on which person or persons that the Government believes that it can prove, beyond a reasonable doubt, knowingly possessed, possessed with the intent to distribute and/or distributed (in this case) marijuana, or conspired to do the same. (Conspiracy, basically, is an agreement between or among the accused and one or more persons to commit a federal drug offense.) Again, a very factually specific analysis. The best course of action that the person can take, legally, is to retain legal counsel immediately. Doing so now will provide the accused (or potentially accused) a tremendous advantage in dealing with the possible criminal matter and apparent actual property seizure/forfeiture action. It may also alleviate the person's being unexpectedly arrested by federal law enforecement agents after an inidctment is returned (if an indictment is returned) at a later time.

Both people may be indicted. Law enforcement is obviously continuing to look for evidence to corroborate the complaints that they have received. Other property may be seized if it is believed to either have been used during the commission of illegal activity or if it believed to have been acquired thru illegal funds.

As a former federal prosecutor, I can tell you that it is possible, in some cases, that some co-conspirators may be charged even though that person may have never actually dealt drugs, provided there is sufficient proof to show that they have otherwise furthered the object of the conspiracy in some way. For example, "mules" or off-loaders of drugs are often charged even though they did not actually deal drugs. I agree with the other attorneys who suggest that it is important that you contact your own attorney as soon as possible to discuss your own situation.
