We own 2 single family rental houses as well as a REIT (VNQ). But we also own bonds. AA is in my signature. We bought the rentals several years ago when prices were very low. No mortgages, no management cost. We've been extremely happy with both the steady cashflow and the appreciation. Workload is negligible.
I don't view investment real estate as a bond alternative. It's a unique asset class that we like in the AA, but only to a point. We also like the role that bonds play.
When I was 48 with only a few years to go, we were 100% equities and bouncing around in a sea of post-retirement investment ideas. We had no solid understanding of what our early-retirement AA needed to be and why. About a year after retiring, and lots of reading, we finally got a handle on what we wanted to own for the long haul, and how we wanted it structured. There was some mildly painful unwinding that had to be done to get there. Wish I had planned that more carefully in the years leading up to ER. Sounds to me like OP needs to put together a comprehensive plan first. Then assess how or if this condo fits into the plan.
