Hi,
@Dicey. I admire your courage in making your Personal Advisor admission!
Based on my limited understanding:
1) Bonds and real estate have similarities, but also differences. To me it seems that in a serious crash, rents can go down almost exactly when bonds go up. Or, bonds could go up early in a crash, while rents respond slowly. Or bonds can go up while the renter who lost a job stiffs you on rent and takes months to be evicted. Individual rental properties cannot easily be sold in small bits to buy stocks that become cheap in a crash; bond funds can. I too have a portfolio that is heavy on real estate, but personally I don't think of bonds and real estate as equivalent.
2) I view stocks, REITs, rental real estate, bonds, cash, pensions, Social Security, gold, and commodities as asset classes that each have significant differences.
3) In your shoes, I wouldn't go all stock. I'd reserve some cash and bonds, maybe in a 1:2 ratio, to at least cover the risk of a tenant stiffing you during a recession. Even if the cash+bonds is just 9% or 10% of financial assets. Judgment call.
Fwiw, my overall portfolio excluding SS is roughly 10.5% home equity, 31.5% rental equity, 10% pension (by contribution, 20% by value...most similar to bonds), 32% stock, 13% bonds, 3% cash. Arguably I'm too convervative, but because of my sequence of payments (I draw down investments soon, then draw pensions/SS) I have a shorter timeframe for the financial assets than someone who will draw gradually from age 60 to 100.
4) I think you can manage this stuff fine without paying Vanguard's personal advisor service. That said, obviously it's cheaper than most non-Vanguard advisors.
5) Despite 3, you have lots of resources and probably will do great with any allocation decision of your financial assets. That's one reason I vote DIY on 4....just keep your investment costs low, be happy that you are already diversified (rentals, pension / SS, financial assets), and have a good time.
