If someone withheld such information from me. I would be offended and outraged. There is basis for debate about how early to divulge such information, but without any question, it must be before the closing of the shidduch is inevitable. It is occasional that the omitting of information is an act of aggression. In cases such as the issues listed here, it is clearly aggressive, and there is NO halachic permission to do so.
The entire notion of keeping secrets is antithetical to the concept of marriage. Husbands and wives may not keep secrets from each other. If they do, they are in violation of their relationship. That accounts for money matters, family matters, even issues pertaining to job and social relationships. Ask any therapist with experience working with cases of marital difficulties. The secrets are usually one of the biggest issues. To begin a shidduch with hiding information is getting started on the WRONG foot. That must be avoided completely.
