Real estate depreciation is a worrisome event especially if the property is indebted to an arm's length party.

History, Charts & Curated Readings
"Progress, far from consisting in change, depends on retentiveness. When change is absolute there remains no being to improve and no direction is set for possible improvement; and when experience is not retained, as among savages, infancy is perpetual. Those who cannot remember the past are condemned to repeat it." George Santayana Vol. I, Reason in Common Sense
"History, real solemn history, I cannot be interested in.... I read it a little as a duty; but it tells me nothing that does not either vex or weary me. The quarrels of popes and kings, with wars and pestilences in every page; the men all so good for nothing, and hardly any women at all - it is very tiresome." Jane Austen spoken by Catherine Morland in 'Northanger Abbey'
