The problem isn't really whether prices are going up or down. The problem is that you're looking at it like an investment, but you need to figure out when *you* actually need an apartment. Because if you wait for the perfect moment, you could be waiting forever, and the decision to buy depends on a ton of factors, not just the price chart.
A friend of mine was in a similar situation a couple of years ago. She spent half a year looking at listings, waiting for prices to drop, and when she finally decided to buy, she realized that over those six months she'd saved exactly zero on risk management. But she'd spent half a year in uncertainty. You know what saved her? She just did the math: the rent she was paying plus all the extra expenses during those six months of waiting - that's real money that just disappeared. And she wouldn't have gotten it back even if prices had dropped a few percent.
Here's what I'd advise: don't try to predict the market as a whole, look specifically at your own neighborhood. Are prices actually going up where you want to buy? Maybe one micro-district is getting pricier while the next one over is holding steady. Second thing - be honest with yourself about your situation: when will money stop being a problem, where do you want to live in life, do you have plans for a family. If all of that points to you being ready right now, then waiting isn't an investment, it's wasted time and real money spent on rent. If you're not ready - then yeah, wait, but you're not waiting for prices to drop, you're waiting for yourself to be ready.
