How can I tell if an offer meets the preferences of the Seller?

Easily. When you click on the Offer Details for a particular offer, you can see whether or not a particular term of the offer meets the expectation of the Seller. To the right of each offer term, you will see between one and five grey house icons. The more icons you see to the right of an offer term, the more an offer meets seller preferences for that offer term.

The Snap Score of an offer whose Net Offer Price (i.e., Offer Price minus Seller Subsidy) is below the Reserve Price of the seller will be impacted negatively.

For each Snap Door listing, the preferences of the Seller will be determined by the Seller. Seller preference can therefore vary from listing to listing.
