We need a lot more information. Does that $60K include taxes, medical insurance until age 65, repairs on the rental, replacement vehicles when yours die, dog breeding expenses (what happens if the litter is only 1 or 2 puppies - my brother had this happen twice and took a loss both times), etc?
Have you estimated what your social security benefits will be? Remember that benefits are calculated based on the highest 35 years of earnings - a bunch of zeros won’t help that calculation. I read recently that the average benefit is less than $1400 a month. And the earlier you claim, the lower the benefit.
Think of the IRA and social security as the pots of money that will replace your wages. For a 30 year retirement, a rule of thumb (and your circumstances may differ since you are only 53 and could be looking at a 40+ year retirement) is to figure on a 4% withdrawal rate from your investments (50/50 asset allocation) at time of retirement and then adjust by inflation for annual withdrawals thereafter. With $580K, that works out to $23,200 a year, assuming your cash is invested and your overall allocation is 50% stock/50% bonds. So, you need $36,800 a year from other sources to meet your $60K objective.
Hope this helps.
