First(main) array:

    [0] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1201
        )

    [1] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1200
        )

    [2] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1196
        )

    [3] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1193
        )

    [4] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1191
        )

    [5] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1145
        )

    [6] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1144
        )

    [7] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1139
        )

    [8] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1135
        )

    [9] => stdClass Object
        (
            [user_type] => U
            [user_id] => 156
            [property_id] => 1053
        )
)

Second array:

Array
(
    [0] => stdClass Object
        (
            [bounced_id] => 2
            [user_id] => 156
            [property_id] => 1193
        )

    [1] => stdClass Object
        (
            [bounced_id] => 1
            [user_id] => 156
            [property_id] => 1191
        )

    [2] => stdClass Object
        (
            [bounced_id] => 26
            [user_id] => 156
            [property_id] => 1200

One way would be just to loop both arrays and a container. Under the loop, if your particular key matches, put the items their first that matches (sort of filtering), then after thats done, merge the rest.

$result = array(); // container
foreach($array2 as $k2 => $val2) {
    foreach($array1 as $k1 => $val1) {
        if($val2->property_id == $val1->property_id) { // if it matches
            $result[] = $val1; // put it inside
            unset($array2[$k2], $array1[$k1]); // remove to continue next set
            break;
        }
    }
}
$result = array_merge($result, $array1); // merge the rest

Sample Output

if I understood you correctly - you need to find differencies between first and second, and then append that elements to second array

$array_diff = array_diff($first,$second);
$array_result = array_merge($second, $array_diff);
