However, all in all, a structural risk arises that affects the profitability of the property.<\/p><p data-start=\"1207\" data-end=\"1236\">Typical causes are<\/p><ul data-start=\"1237\" data-end=\"1347\"><li data-section-id=\"1f1g16u\" data-start=\"1237\" data-end=\"1274\">Lack of structure in the processes<\/li><li data-section-id=\"58ev2q\" data-start=\"1275\" data-end=\"1302\">Unclear responsibilities<\/li><li data-section-id=\"ncie1s\" data-start=\"1303\" data-end=\"1347\">Decisions without sufficient review<\/li><\/ul><p data-start=\"1349\" data-end=\"1431\">This is precisely why it makes sense to consciously consider the typical sources of error.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-786720d elementor-widget elementor-widget-heading\" data-id=\"786720d\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Incorrect service charge settlement<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-9e5c3d7 elementor-widget elementor-widget-text-editor\" data-id=\"9e5c3d7\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p data-start=\"1480\" data-end=\"1689\">A particularly classic error lies in the preparation of the service charge statement.
