You separate "Investments" and "Retirement Accounts," but I'll assume the assets are all invested in a 75/25 stock/bond allocation, or a proportion which is higher in stocks. If so, then you have $879K in assets eligible for a 4% SWR, or $35,160 a year. Add to that your $14K in rental income, and you have $49,160 in income a year. Thus, if I am interpreting your numbers correctly, you do not yet have enough to satisfy your requirement of $60K a year.
Is the property whose value you list the same one providing the rental income? If so, you could liquidate the property, invest the proceeds, and (assuming for a moment that they were completely tax and selling cost free) have $1,219,000. This would still only give you $48,760 per year.
If, somehow, the property value you list is *different* property than the one producing rental income, then you could liquidate that property, get $48,760 + 14,000 = $62,760 per year, and retire. But something tells me that's not what we're talking about here.
I'm wondering what made you ask? Do you have questions about how the 4% rule works? What made you think that these assets were sufficient to yield 60K?
