Buying in October may or may not be better. The price does not depend solely on the interest rate policy, but in particular on the consequences that investors see for REITs. And investors do not always act rationally. It is therefore also possible that you will already be chasing prices in October.
As we will only know later what would have been right, I am simply buying regularly in the current phase using a savings plan.
Due to the upcoming US elections in November, I would not necessarily bet on October here. I agree with you about the bottoming out. I entered $VICI and $O in March with a 1st tranche and I visit both monthly in my savings plan. At the end of the year, I wanted to enter with a larger position if necessary.
