                       owner.ownername = mownername;
                       owner.ownertype = ownertype;
                       owner.owneraddress = owneraddress;
                       owner.propertymanage = propertymanage;

                    })
                    .then(result=>{
                              res.render('/user/home_single');
                                  })
                    .catch(err=> {
