OK I got my building insurance quote back. Absa's premium was R384-and-change per month for the building insurance. I got a quote through my broker for the same replacement value, but with a ton of extras like pet insurance (like WTF), visitor's claims insurance (yes, really) and more, and the quote came back as R303-and-change. My home contents insurance is already with them, so the total premium would be R567.20. That covers the building for R2.1mil and home contents of R350k. Home contents amount needs to be updated, it's probably closer to R400k by now.
