How often do old apartments get bought by developers for a knock-down and redevelopment? I have not seen or heard of this happening much in Sydney so my assumption is it's extremely rare. I ask this cause my family relative A wants to purchase an apartment in Strathfield off my family relative B at market value as they are looking to up-size. Relative-A believes that it's a waste sell the properly which I agree with, but I don't agree with buying the apartment at market value. Relative-A believes that with Strathfield expected to have the shopping centre redeveloped, it'll have flow on effects on neighbouring apartments and trigger knock-downs and redevelopment of near-by apartments. I have doubts that it would happen as I haven't seen many blocks of apartments being knocked down for redevelopment. I'd imagine it'd be extremely expensive and only worth-while if the zoning was to change.
