class Estates(models.Model):
    userprofile = models.ForeignKey(UserProfile, verbose_name=u'Пользователь', default=1)

class UserProfile(models.Model):
    user = models.ForeignKey(User, unique=True, verbose_name=u'Пользователь')

И стандартная User

            formset.save()
            estates_objects = formset.save(commit=False)
formset.save()
            for obj in estates_objects:
                obj.userprofile_id = request.user.id  # :( проблема тут
