Over period equity has grown but rent not, what to do?

[Rajesh P.]

I bought one house 10yrs back which appriciated by 2.5 times; however the rent has not increased in the same ratio. Can Guru's provide some advice. Should I settle down with the rent and keep the house assuming it will appreciate or sell it and invest the equity somewhere (btw I am assuming real estate growth in nearby Neighbourhood would be same). Any other suggestion?
