Massey, Cottesloe is a trophy suburb, and yes some houses and suburbs have gone down. 69 Wright St, Highgate was asking $1.69m three years ago, finally sold for $1.2 this year. BUT take a look at the top selling suburbs in REIWA data in West today. Most are cheapies and it has been that way for 4 years. Any body following your advice and waiting since 2010 to buy a house HAS LOST $200,000 That is approx $100k paid in rent (thanks by the way) and the increase of $100k in the price of entry level houses. 19 Aries Place Rockingham $330k in peak, $300k 3 years ago just sold for over $400k. Plenty more of them.
Actually I do believe something you posted. Looked up Donnybrook on realestate.com.au for a small place there are a lot of for sale signs, talk about a dud, how much you lost on that again. Oh yhats right you made more than that trading species,
