My policies are similar.My terms are: If the order is cancelled before I leave the house, no charge. If I do the inspection, I charge a “trip fee”, usually $150. If it is cancelled after I return to office, I charge trip fee plus “data collection” (I.e, taking comp pics), usually an extra $100. There are times when I have typed most of the report when I “get the call”. Most times, I get the whole fee. I rarely get pushback because they have already collected the whole fee before they ordered the appraisal.
