You could also use the Illuminate\Validation\Rules\RequiredIf rule directly.

Note: This rule is available in Laravel 5.6 and up.

class SomeRequest extends FormRequest
{
    ...
    public function rules()
    {
        return [
            'sale_price' => new RequiredIf($this->list_type == 'For Sale'),
            'rent_price' => new RequiredIf($this->list_type == 'For Rent'),
        ];
    }
}

And if you need to use multiple rules, then you can pass in an array.

public function rules()
{
    return [
        'sale_price' => [
            new RequiredIf($this->list_type == 'For Sale'),
            'numeric', 
            'string',
            ...
        ]
    ];
}
