Question: How do I stay calm in crazy property market?
Answer: Be fearful when others are greedy and greedy when others are fearful. This rule should always hold you in good stead
If you want an unemotional seller then look for mortgagee sellers.
Consider how much you would pay if you were to rent the property yourself and then calculate mortgage + holding costs. Maybe if its your dream home its better to rent it vs buy for the moment until the market cools
