It's possible but there are couple of major concerns.
1) Workers comp generally can be counted as income because it's "temporary".
2) The same thing can apply to the SSD unless you've been found to be permanently disabled and the SSD will continue for at least 3 years.
On the other hand, the money from your foster care can be counted as long as it will continue.
The only way to find out what your options are is to apply with a lender (like me) for a pre-approval.
