What are the REALISTIC chances of being able to eventually obtain the deed and remain as resident of the condo my deceased aunt owned .

From your description, it sounds as though your inheritance is subject to the Medicaid Estate Recovery Program.  This means that you cannot inherit until Medicaid is reimbursed for the cost of your aunt's care, at abouct $6,000-6,500/month.  While Medicaid may waive recovery for a child who resided in the home, providing care which delayed the need for a nursing home, for at least two years, there is no similar provision for a niece or nephew.  A niece or nephew would have to argue that Medicaid recovering from the estate, as Congress requires, would work a "undue hardship," forcing them onto public assistance.  For help in making this argument, see a local elder law attorney.  You can find one on the website of the National Academy of Elder Law Attorneys (www.naela.org).
