A "we buy houses" company offered me cash in 7 days. How does that compare to listing with an agent?

A cash offer promising a close in about a week trades speed and certainty for a lower price, since these buyers are pricing in a resale profit and the convenience they are selling you. Listing with an agent typically takes longer to reach a closed sale but exposes the home to more buyers competing for it, which usually produces a higher net price. Brian Beatty shows sellers both numbers side by side so the tradeoff is a real choice, not a guess.
