You're on the right track! $41,000 to the condo. $51,500 into bank CDs for the house down payment. Get as much as you possibly can into the company 401k for 2014--$17,500 is the max allowed in a year. This will put your income under the limit to contribute to a ROTH, but probably too much to contribute the maximum. I'd have the max ready to go just in case --$5,500--though it'll probably be closer to $3,000-$3,500.

Don't put any extra toward your mother's condo, because the interest rate on the mortgage is low enough, you'll get a better return putting anything extra in stocks.
Do some research on this site and others about specific funds to purchase. If you want your stash to generate $6,000/mo in retirement, saving $20,000/yr is just about right (I'd suggest a couple thousand more if you can) you just need to get it invested.
It seems like an HSA might also be helpful to you, but since I don't have access to one myself, I'll let someone else chime in about them.
