I've worked with 2 different loan officers here that do USDA and both have been able to close the loans in under 45 days. I've even done 2 transactions that were new-construction using the loan. By structuring it correctly, the loan's closing costs can be covered by the builder/seller and it then really is a no cost purchase.
I don't know if you were looking at a program like this specifically, but there you go! Feel free to contact me if you have any other questions! You can find my information by clicking on my picture.
And good luck at finding your new home!

I checked in with my trusted lender and his response was below.
There are USDA loans if he purchases in the right neighborhood and VA loans if he is a veteran. Other than that there is conventional and FHA loans. I'm not aware of anything specifically for Federal Employees but would be happy to talk with him.
