Retirement tax questions

Ya I wish i could do that but I'm 38 have 2 kids 12 and 16 and a wife who dosent work and live in a **bleep**hole nys where my taxes are 4k a year on a 100k house with no land. I have almost 200k in my 401k only money I could ever save just because u don't have access to it. My grandmother was very wealthy and Has a big estate that needs to be settled but probably will take years. this ira was separate but need to make money last untill estate is settled then I should be able to retire in 15 years if I make it that long.
