Best time to take additional inquiries is when you have several already mathematically . Constant sprees don't make any sense, but spacing them out to make one's applications in groups is a good approach.
Better to garden it all at the same time, if it'd save you money, just apply now. Worst case you get denied and have to wait six months or whatever, which would be about the same time as just waiting anyway if trying to optimize for best chance, so this inquiry costs you next to nothing.
You guys are so right. I don't know what I was so worried about. I am definitely going to make an appointment with a loan officer at the bank next week.
