Why the property is comparatively too high?

I wish to buy a another house for my parents very near to a Hospital but it seems like either it is out of budget(1.5cr to 3cr) or either is not a society Just a generic appartments. What happened it's a surprise for me. I am the only daughter child and wish to support them when I am not in Town while travelling for business purposes. So I thought if they could stay near to a hospital 🏥 but this idea is vague seems like.
