I'm single, 46. I have 205k in a Roth IRA (Vanguard Target Retirement 2050 Fund). I'm trying to max it out every year. I have two houses- hopefully both paid off around age 65 and may be worth around 800k after taxes. I'm in a life change right now- moved to help take care of a parent. Probably making very little for the next two years but after that, if possible, I'll try to add an additional 500/month to a solo 401k. I think I'll need about 60k/year (in today's money) for retirement. Any advice is appreciated.
