It's best to start by making a list of criteria: budget, neighbourhood, transport, infrastructure. Next, you should study the market and analyse the offers. It also helps to learn about real estate trends and expert advice — for example, at https://lyukos.com/news/ which has materials on the housing market, price trends, and advice on how to find the best place to live. This allows you to make decisions with confidence and not waste time on random options, but choose what really suits your needs.
