I am a bit confused as to why you chose to do this, particularly if you knew that you would lose your homestead exemption and have to spend down the proceeds of the sale. Is it that you don't intend to seek SSI or Medicaid benefits in the near future?
There shouldn't be any attempt to recoup money for benefits extended prior to the sale of your home, at least insofar as it was protected by the homestead exemption, as up to the date of sale it was an exempt asset.
