Good morning Chrissy, and thank you for writing. It appears that your loan officer does not want to be the bearer of bad news and avoided giving you an answer right away.
There is no penalty on your credit scores for pulling many credit inquiries when you shop for a mortgage, as long as you pull them right away. I'd go with a lender who is more responsive, explain the situation, and ask if a "rapid re-score" might help you. You can get contact multiple lenders easily here. https://themortgagereports.com/ratequote
The rapid re-score updates your report (and possibly improves your score) within a couple of days. Only a lender can order a rapid re-score, but the cost is low and it does work fast.
If your credit score is very low, however, a re-score might not help you enough. If you have a copy of your score, and it's in the 500 range, you may need more time to bring it up to minimum lender standards, or you may need to make a larger down payment.
One thing you can do is call your loan officer and ask if they issued an "adverse action notice," which is required by law if they decline your loan application. If they did, get a copy, and it should tell you what the issues were, if any.
