    Stricter Pursue picks

    We've tightened what earns a Pursue. A home now needs a published valuation, a strategy that still makes money after real running costs and lender stress tests, and no listing problems that would stop a mortgage. You'll see fewer Pursues, and each one has been checked harder.
