My sister bought a house that needed most of the walls pulled down, new roof etc & they have nearly finished renovating it.

Sure, there has been lots of times where they have wanted the throw in the towel as sell it as a project but they stuck to it.

It is now really gorgeous & worth at least 3 times what they paid for it (before it is finished).

Renovate I say. You will get such a buzz from the finshed results of your own work & own design.

Good luck :-)
