conflict in stories

I reside in Texas where I have seen a number of conflicts in stories about Medicaid denying benefits despite a ladybird deed signed and in effect. I met with an Elder Attorney who has advised that my aunt, who currently resides with me, she having an annuity of approx 200k, liquidate same and purchase my house in order to meet the spend down, then do a ladybird deed naming me as beneficiary along with it being placed in an irrovocable trust naming me as trustee. My question here is can Medicaid deny her based on the fact that I may be required (as indicated in a number of posts) to have to denounce and sign off a revocation of the ladybird deed before consideration and approval by Medicaid? Currently, we are looking at facilities for which to have her placed in the next 60-90 days. also, should I sell to my aunt as indicated above, what happens to my homestead as I will no longer be listed on the title?...will or can same then be homesteaded if feasible in my aunt's name and if so, as holding Durable POA, can I do so on her behalf?
