Answer 1

This is possible with ES 2.x using pipeline aggregations. First we need to aggregate on addresses. Then we use two aggregations, one which gets the latest_date and other which gets latest date for sold status. Then we check if both dates match with bucket selector aggregation. This is how it looks.

{
  "size": 0,
  "aggs": {
    "unique_address": {
      "terms": {
        "field": "address",
        "size": 10
      },
      "aggs": {
        "latest_date": {
          "max": {
            "field": "date"
          }
        },
        "filter_sold": {
          "filter": {
            "term": {
              "status": "sold"
            }
          },
          "aggs": {
            "latest_sold_date": {
              "max": {
                "field": "date"
              }
            }
          }
        },
        "should_we_consider": {
          "bucket_selector": {
            "buckets_path": {
              "my_var1": "latest_date",
              "my_var2": "filter_sold>latest_sold_date"
            },
            "script": "my_var1 == my_var2"
          }
        }
      }
    }
  }
}

Hope this helps!!
