Old guy newbie: is it too late for me?

[Bradley R Stillabower]

The BP community seems to cater primarily to the "Young and the (financially) Restless" , but I'm a 55yo retired military and soon-to-be-retired federal employee (14 months), considering one final encore career for 5-8 more years before fully retiring.  Wondering if that is enough time to accumulate a portfolio of investment properties that will generate between $50k-$100k per year of income to (help) pay for may daughter's grad school (student loan debt is anathema to me), and then continue to augment our pension and stock portfolio throughout retirement and finally leave as inheritance.  My only real estate experience is the four primary residences we've bought/sold for ourselves over the past 25+ years, one of which we tried to keep and rent, (but not a good experience).  My research so far is leading me towards small multi-family properties as the most efficient path toward my goal.

If I do pursue this, what is the best use of my time over this next year to educate and prepare?  A real estate license?   A BP boot camp?  Can I start with the Multi-family Boot Camp, or does it build on the Rookie Boot Camp?

I think I've read most of the free BP content by now, and it's been a fantastic one-stop-shop of educational material.  The Multi-family webinar was a very tempting intro to the analysis tools, which, as a numbers/data guy, are really enlightening, and comforting to know those tools are available.

Thank you,

Brad
