If I was in your shoes, I would be happy with your current asset allocation, except for one thing. Are any of your investment accounts a taxable brokerage account instead of a retirement account? Taxable brokerages function as bank accounts - you can put as much money in and out as you want at any time, without any penalties. You pay earned income tax on capital gains, but there is a tax loophole to take advantage of with dividends that reduces your tax rate to nearly zero. I would put nearly all of the $80,000 into a taxable brokerage account, with 100% allocated to a passive index fund that pays a high dividend.
If you hold a stock for more than 60 days, subsequent dividends are considered 'qualified'. These dividends are taxed at 0%/0%/15%/15%/20%/20%/20% for the 10%/15%/25%/28%/33%/35%/39.6% tax brackets. There is nothing else that comes close to such low tax rates - with retirement accounts, you're paying the higher earned income tax rates either up front when you put money in (with a Roth), or when you withdraw (with an IRA). As long as you don't sell the principal stocks that you buy in the taxable account (buy & hold the initial shares forever), you will get a nice little income stream and pay almost no tax. For the $80,000 in cash you have, that would buy you about $200.00 a month in qualified dividends - cash that is immediately available for use, and is paid quarterly. Not to mention the principal appreciating in value over long periods of time (your 80,000 will appreciate in value 6% a year on average on top of the dividends), and your dividend yield increasing as the economy grows (figure 6% a year increase, but it could be a LOT more - 10% a year or more, if the bull market doesn't die). You can set your brokerage up to reinvest the dividends automatically too if you are doing well enough to not need them.
It's a great tool and I use this strategy myself. I have about 80% of my net worth in a taxable brokerage account; the account currently holds $141,000 and yields $5,000 in dividends a year. I receive between $300 and $1,100 a month depending on the month in dividends, so I have a backup cash stream taxed at a flat 0% (I make less than 36,000 a year) if I can't find work. At your level of net worth, you have enough cash flow from rental investment and part-time work to put virtually all of your $80,000 to use in this strategy. At your age, you could really come out ahead over the 14 or so years between now and when you can utilize your other retirement accounts.
