Corrections, downturns, peaks, troughs are based on History. 5 years ago the banks were saying the Irish propert market had peaked, they're now saying it's gone beyond peak. In reality they haven't a clue !! Ireland is a different market now, ECB controlled interest rates, massive immigration. I take the doom and gloom stories with a pinch of salt.
Ultimately, property investment is a long term project and will appreciate. You need to stress test your loans and make sure you can afford an interest rate of 5%/6%, coupled with periods of non-rental.
The buy, release equity, buy system does work but just be CAREFUL or you could be swimming with the fishes !
