Interest rates have been rising for the last 6 months, they have been falling for the past 5 decades and have oscillated up and down during that path downwards.
We have to keep in mind interest rates are still incredibly low by historic standards.
As @Evan Polaski mentioned, interest rates certainly affect all investment returns - some more than others.
What hasn't been mentioned is that the reason why rates (and really only longer maturity rates, short term rates are still near 0%) are rising, and that's inflation.
Apartments outperform in inflationary environments as rental growth historically outpaces inflation - which is why rental real estate is considered an excellent hedge against inflation.
While we may see multiple reduction/cap rate decompression, top line revenue and NOI growth will grow at a faster rate, which is the numerator in the value equation (NOI/Cap Rate = Value), so we will likely see prices continue to rise or at least stay flat. In other words, yields (cash-flow) will increase.
We will see a spike of inflation and higher rates, although still historically low, for a year or so before rates continue their trend downwards.
There is far too much sovereign debt outstanding which can't be sustained in a higher rate environment. The central banks of the world will ramp up their buying of long maturing bonds to bring rates down.
Technology and automation will continue to be a major deflationary force that will also temper long term inflation and keep rates relatively low.
The investment thesis into multifamily is as strong as it ever was, homeownership is increasingly unaffordable, construction delays due to the pandemic will further add to supply constraints - increasing absorption rates, occupancy, and rent growth.
The best time to buy MF was in the last decade, the next best time is right now.
