Retirement tax questions

Thank you because a previous comment just said I WOULD have my heirs going through probate under a trust. This is my confusion because I get conflicting answers. I only want the children to retain the house without probate and be able to easily assume the VA mortgage we currently have. Now if you say DO NOT put them on the deed now then I just need to put them in the trust as heirs to the property, yes? I don't mean to keep asking the same question but I keep getting different answers. I need the EXPERT to respond. Thank you.
