For most areas, the same holds for property taxes. You will have to pay taxes for the days from the date of settlement until the next bill is due and still have enough for 2 months reserves.
If you are purchase a home, you will also have to reimburse the sellers for the amount they paid ahead from the date of settlement. These costs can add up quickly.
By the way, these principles apply to every mortgage, not just FHA.
Both Bill and Lew answers are more or less spot on. Also, month ends closing do not apply to FHA loans solely. Its a universal consideration that applies to all types of loans. Fo the reasons again given by Bill and Lew, as a happy medium I personally try to close my loans always between the 15th and 25th of any given month.
