1. This type of fee is a FC when charged after the loan originates.
2. If it's paid at consummation or withheld from draws, then it's a PFC.
3. If it's billed or held for collection at the end of the loan, then it's an ordinary FC, not prepaid.
4. TIL disclosures are based on the best information available at the time the disclosures must be given.
5. If you don't have firm information at consummation, then you must estimate.
6. If construction runs long or problems develop & more title search charges are necessary, that doesn't render your original disclosures inaccurate if you followed #4 and #5.
