I'll be 48 this year; and I believe I have similar views; I don't owe much on my home in comparison to what homes are selling for now a days... but, I can't push myself to pay it off because I haven't hit my number yet for savings... to me, having money in the taxable account for a longer period of time is more beneficial (valuable) than paying off my home right now.
So, I do the following:
fully fund 401k
fully fund spousal traditional IRA (Vanguard VTSAX - Total Stock Market)
fully fund roth IRA (Vanguard VGSLX - REIT)
fully fund H.S.A (Fidelity Nasdaq Index)
6,000 - 18,000 additional into a taxable vanguard account with a goal of 800,000 or more befor I consider leaving my company... Then, assuming I am 59 1/2, I would pull from my 401k and IRA, but keep my tax bracket below 15% and put it all in the taxable account year over year and focus on living on dividends from the taxable account... the objective is to never touch 1 share if possible... I started late in life, so I may or may not hit that goal, but I'm really trying. Take the dividens + social security and I Just may be living better in retirement than while working! :)
Sure wish I would have found this site and JLCollinsNH back in 2009. These guys and their readers have litterally changed my future.
