5 to 7 days should be enough.
Yes, 7 days is fine. Howver, it's getting late to be seeding a new lawn in Iowa. Early fall is by far the optimum time, followed by early spring. Be prepared to do a lot of watering, and you'll have serious competition from weeds.
Good point. But I've had fair results seeding before the end of May here in central Iowa. It's been pretty cool this year.
