Thanks for clarifing your questions.
SSD is not a needs based income. There for, receiving the inheritance will not reduce your SSD payments.
However, if you have any other needs based benefits, such as Medicaid, those payments and eligibility may be reduced or eliminated.
Also, if you are receiving and state or VA institutional type care, they may want to attach part or all of the inheritance for reimbursement of care.
Regarding state institutional care and extended care facilities, nurising homes, etc. In some states, they can go back 10 years to attach assetts to help pay for the care. If you anticpate, as a result of your disability, that you may be in one of these type institutions within the next 10 years, it woud be a precautionary measure to place this inheritance ina special needs trust.
The trust needs to be established before you receive the money from the sale of the house.
