I would seek the counsel of an attorney. Given all of your husband's mental problems, he may need someone to act in his behalf. We did a divorce once where the wife was bi-polar, obsessive compulsive and would deliberately hurt herself (like taking a pair of tweezers to her face). After filing for divorce (on behalf of the husband), we asked the court to appoint a guardian ad litem for the wife. This was for the husband's protection, as well as hers. Instead of spending all that money to upgrade your current home, is there anyway YOU could use it to set yourself up someplace else? This would solve your problem about how to remove him from the home.
