Single model using many-to-many relationship with several other models - eloquent

Question

I want to have a single table containing information about people (name, phone, email) called contacts that can then be associated with several other tables (clients, properties, jobs). However, I have no clue how to approach this through Eloquent. I considered having 2 additional fields in the contacts table, an entity_id and an entity_type to identify the associated records in the other tables, but I am hoping there is a cleaner, more Laravel way to accomplish this.
create_contacts_table.php
Schema::create('contacts', function (Blueprint $table) {
$table->id();
$table->string('first_name')->nullable();
$table->string('last_name')->nullable();
$table->string('phone')->nullable();
$table->string('email')->nullable();
$table->timestamps();
});
create_clients_table.php
Schema::create('clients', function (Blueprint $table) {
$table->id();
$table->string('name');
$table->string('address_1');
$table->string('address_2')->nullable();
$table->string('city')->nullable();
$table->string('state')->nullable();
$table->integer('zip_code')->nullable();
$table->timestamps();
});
create_properties_table.php
Schema::create('properties', function (Blueprint $table) {
$table->id();
$table->string('address_1');
$table->string('address_2')->nullable();
$table->string('city');
$table->string('state');
$table->integer('zip_code');
$table->timestamps();
});
