                    {
                            $asset_arr[$i]['property_id'] = $this->id;
                            $asset_arr[$i]['location_id'] = $req->location_id[$i];
                            $asset_arr[$i]['model_id'] = $req->model_id[$i];
                            $asset_arr[$i]['appliance_owner'] = $req->appliance_owner[$i];
                            $asset_arr[$i]['current'] = $req->current[$i];
                            if($req->installdate[$i]!=''){
                                $asset_arr[$i]['installdate'] = date('Y-m-d',strtotime($req->installdate[$i]));
                            }
                            $asset_arr[$i]['comment'] = $req->comment[$i];
                    }
                    if(!empty($asset_arr)){

                            Asset::insert($asset_arr);
                    }

insert() is not an Eloquent method, so you'll need to add timestamps manually. Do something like this:

$asset_arr[$i]['created_at'] = Carbon::now();
$asset_arr[$i]['updated_at'] = Carbon::now();
