If you're not able to find off market/value add deals, you kind of need to accept lower cap rates in this market (in residential). That doesn't meant that you have to accept deals that don't cashflow. Get the upside of inflation through rental and price appreciation without putting yourself in a liquidity crunch if the unexpected happens.
I agree that inflation is likely to run hotter than it has over the last 10 years, and residential housing will likely run above overall CPI for at least the next 5 with the strong demographic support from Millennials moving from apartments to single family homes, but I would not expect 5%+ inflation for very long. If the overall level of CPI exceeds 3% for more than a year, the Fed will have to give up it's current stance that inflation is transitory. This would cause to them to raise rates/stop asset purchases in order to reduce aggregate demand in the economy. The likely result is a drop in stocks and other financial risk assets.
Also, I expect the Biden administration to drop the tariffs on lumber from Canada to release the pressure on lumber prices. This would help builders ramp up new home construction. Coupled with a lifting of the foreclosure moratorium and higher mortgage rates (coming), supply/demand should be more balanced over time.
All of that said, I LOVE buying cash flowing rentals w/ leverage right now. I think the next 5 years are going to be great! And much better than owning AGG etf in your investment portfolio.
