What you can do is to _reindex your data to a dest index, delete your original one and then _reindex again to your original one with the new mapping.

Reindex:

POST _reindex   
{
  "source": {
    "index": "sale_property_development_j"
  },
  "dest": {
    "index": "new_sale_property_development_j"
  }
}

Delete original index:

DELETE sale_property_development_j

Create requested mapping:

PUT sale_property_development_j
{
   "mappings":{
     "property":{
       "properties": {
         "redcash_sale": {
           "type": "object",
           "enabled": false
          }
       }
     }
  }
}

Reindex again:

POST _reindex?wait_for_completion=false    
{
  "source": {
    "index": "new_sale_property_development_j"
  },
  "dest": {
    "index": "sale_property_development_j"
  }
}

Finally:

DELETE new_sale_property_development_j

It's a nice to have solution
