CrossCountry Mortgage

Hello! We are first time homebuyers that have had credit issues in the past. We have steadily been rebuilding. We want to purchase our first home and recently got pre approved through Cross Country Mortgage. Is this a good company? Anyone have experience going through a sale with them? I’m so nervous that something will go wrong and we won’t close. I just don’t know anything about this process. We have all our docs they’ve requested. We have our down payment. And now we have sound the house. All advice and experience welcome!
