OK.???? I asked you what (or when) you mean by the term "to begin with". I don't have a clue how your response is supposed to answer the question.
Erase:
7. to give way to effacement readily or easily.
8. to obliterate characters, letters, markings, etc., from something.
"Erasing" is merely a term I used in the thread title only in order to avoid repeating the title of topic study. The authors of the study did not use "erase" in any form at any point. It's a cross-sectional study. It certainly does not imply that property values do not change over time.
I inferred the wrong thing.
But I don't see a problem.
Poor people buy low value homes.
That seems natural & fair.
What would you have anyone do about valuation?
What consequences would you expect?
