If only a single set of disclosures are issued for a construction-to-perm loan, but there is no escrow until the permanent phase, should page 4 indicate there is escrow, since there will not be an escrow account for approximately one year?

A closing disclosure will reflect what is happening at closing as far as escrows. If you are requiring them to stablish an escrow account after the one-year construction period, then estimated escrow payment will be reflected in the payment table beginning in Year 2 on page one.
