Saini Bhawan's 'full power backup' claim: investor reality?

The 'full power backup' claim in most projects is a total myth, isn't it? Just moved into Saini Bhawan last month, and I'm already seeing common area backup only, not for the whole flat. This really affects tenant attraction and their willingness to pay good rent, plus long-term resale value. Honestly, it's a major concern for investors. Has anyone else experienced this bait-and-switch with power backup in Chandigarh societies? Also, what about water supply? We've had a couple of low-pressure days; hope it's not a tanker dependency issue down the line. And elevator quality – are those maintenance response times usually slow, or is it just our building? Wondering how these small things impact future ROI and overall property value.
