The quick answer
Pay for the level of help you actually want.
DFW spans a huge number of cities and submarkets. Eaton confirms the exact address and applicable MLS before preparing the listing, rather than treating the metro as one uniform market.
Eaton separates MLS access from seller representation so the difference is clear before you sign: the flat-fee plans are DIY transaction paths; the 1% plan includes CMA/pricing guidance, buyer-agent communication, showing coordination, negotiation and contract-to-close support.
