Knock features and specs

  • Streamlined Buying Process
    Knock simplifies the process of buying a new home by allowing users to make competitive offers without the contingency of selling their current home first.
  • Home Equity Access
    Users can access their home equity before selling, which can be useful for securing a new mortgage or funding the move.

    Knock offers flexibility in timing the move, enabling users to buy and move into a new home before they sell their old one.
  • Dedicated Support
    The service provides dedicated support from real estate experts, which can help in navigating complex transactions.

  • Market Limitations
    The service is not available in all real estate markets, limiting accessibility for some potential users.
  • Complexity of Transactions
    Though Knock simplifies parts of the process, managing two transactions (buying a new home and selling the old one) can still be complex.
