Use tinker to test

php artisan tinker 

//To find resident id
$r=App\Models\Resident::find(1)

//To get all resident properties
$r->properties

//To count all resident properties
$r->properties->count()

//To find resident id(1) neighbourhood trough properties (many to many relationship)
$r->properties->find(5)->neighbourhood->name

//To get all resident id(1) property "property_id"
$r->properties()->pluck('property_id')

//To get distinct(*) neighbourhood
$r->properties()->distinct()->pluck('neighbourhood_id')

//To get all neighbourhood id group by neighbourhood id
$r->properties()->groupBy('neighbourhood_id')->pluck('neighbourhood_id')
