In this market (even now)we are still seeing these letters, this is fro 2020 but am interesting read
In my opinion : As an listing agent we should advise against them to keep a level playing field
NAR Position on Offer Letters to Sellers from Buyers: Click Here
an excerpt from the article :
“To entice a seller to choose their offer, buyers sometimes write “love letters” to describe the many reasons why the seller should “pick them.” While this may seem harmless, these letters can actually pose fair housing risks because they often contain personal information and reveal characteristics of the buyer, such as race, religion, or familial status, which could then be used, knowingly or through unconscious bias, as an unlawful basis for a seller’s decision to accept or reject an offer.”
