No. Just no.
No. Just no. They delayed closing for over two weeks and nearly cost us the house in the process. Sellers were extremely upset because Cityworthless wouldn't answer their phones so their agent couldn't get a straight answer and when they did provide an answer it was vague at best "maybe in a week or so, depends because we're backed up". We couldn't even get a straight answer and we were the borrowers. Of course everything is great when they're signing you up but right before closing the cracks start to show and by then it's too late to switch lenders. Save yourself the heartburn and find a lender that has their act together.
