First, I would pay off all of our debts............Not alot but still enough I would make sure it was a clean slate.
Second, I would buy a house....doesn't have to be elaborate....just convenient for my husband since he is very ill.
Third, I would definitely quit my job......Right now I work full-time, and take care of my husband. Therefore, I would have to look at some good investments for whatever money I don't spend.
Fourth, I would make sure my teenage son goes to college. I would assist my oldest son with some finances and set up a trust for my only grandson.
