I’m afraid your inexperience and naivety is showing.  In addition, It appears reading into your answer you only want “atta boys”, not anything that can in the remotest sense be considered “criticism”.  So instead of opening your self up for learning, you quickly defend your achievement.  Very childish, and totally unproductive.

Most if not all of my contemporary investors can confirm when prices in certain major markets fell 50% - because we lived thru them.  Here’s a synopsis of the Case Shiller Housing Index 2008 - 2011 “Nationally, home prices fell approximately 27% in 2008, but Phoenix experienced a much sharper decline, losing around 56% of its value”.  That was
just 2008, 2009 -2010 nationally prices fell another 13%.  So nationally we had a 40% decline, with Phoenix, Miami, Las Vegas and San Francisco showing 60% + decline.  That’s why I purchased 5 properties in Phoenix area in 2012 - for 60% BELOW what they had previously sold for. 

A more recent example is office properties.   Office values have declined on average 40 - 45 % nationally, with some markets down over. 50%. Here’s an excerpt from an article 
“  In May 2024, for example, the office building at 1740 Broadway in New York, originally purchased for $605 million in 2014, was sold for under $200 million. This underscores the sharp decline in commercial property values in some cases.

Many office building owners financed their properties at low interest rates pre-pandemic. As loans mature and refinancing at today’s elevated rates becomes necessary, the financial burden increases, especially for buildings already struggling with high vacancies. Recent sales reflect severe devaluations. A Washington D.C. office building sold this spring for $16 million, a sharp decline from its $72 million valuation in 2018. These losses are making lenders and investors more cautious about financing office properties.
