I know this is illegal to do if its hud housing but the ssi situation with housing may not be run the same. Usually your ss agent has a set of rules for you that you can obtain from them. If you just ask the agent at the office to get the rules so you know what they are you will be better off. If they ask why you want to rules just say so you know how to stay on the straight and narrow. Most of the SS offices have phone number you can call to if you wanna remain anonymous!
Are you asking about SSI or SSDI income? Many people believe that they are one and the same. They are NOT. SSDI is disability income based on your prior work history. SSI is disability income based on financial eligibility. Your family member is buying the house, not you. You will be renting the house unless it is to be provided to you for free. When you receive SSI and you move you are required to notify social security. They will determine if your benefit changes. If you are actually asking about SSDI, that is NOT based on anything other than prior work history and does not change if you move, buy a house, sell a house, etc.
No that is cool and you will just have to re-apply for fs an medcaid from wherever you move 2. I moved an mine took bout 2 weeks for medicaid and fs got in one week.
