@Anonymous Welcome! Everything went well when they re-pulled our credit. We were able to get preapproved. Our tentative close date is 12/10. We received conditional approval two weeks ago and are just working on providing whatever documents they are requesting 
My best advice is: follow whatever gameplan your consultant gives you. I feel like they're able to target what will get you the most points possible, so we tried to follow what she laid out for us. We also made sure to sign up for credit alerts through FICO and Experian. If something unexpected popped up, we knew about it right away and were able to take care of it right away.
For example, prior to working with Homebuyers, we were working with another credit repair company (long story). I'm not sure exactly what they did, but an old debt of my husband's randomly popped up on his credit report (it had already fallen off and reappeared) while we were in Homebuyers and waiting to finish out our contract with the other company. I don't think it was intentional; I think it was the methods they used. We received an alert that a new debt popped up and we were able to quickly identify it. We reached out to our consultant who was able to give us the best advice and we were able to take care of it without having it show up and potentially set us back.
I would also recommend keeping within the limits they suggest on your open/available credit. We followed AZEO and kept our balances to less than 5%. This paid off for us. In the end, our consultant identified an opportunity for us to gain a few more points. We did what she requested and then she submitted the info to the bureaus to get it updated. So even in the end, there's still an opportunity! Hope this helps!
