Best time for renovations

[Samuel Glantz]

I am looking to start out soon, investing in Saint Louis.  Specifically South city multi family homes. My question, is there a time of year that is better or worse for renovations to happen? I live in Phoenix so all year round here is an okay time for it. I am not familiar with the seasonality of Saint Louis. Like is starting in the winter going to lead to a lot of down time? Or is the perfect time since contractors will be slow and want the work etc..?

Just curious if there is a sweet spot on planing renovations to occur or if it doesn't matter.
