Yes it was true in my case. My lender would not approve me with those disputes on my credit report. It took me 2 months to get it taken off. The final one just came off over the weekend and now I'm pre-approved. Call all 3 credit bureaus and tell them that you are no longer disputing anything on your credit report. Some, creditors will have to contact the credit bureaus to have it taken off.
I had one creditor that I had to call to give authorization for Transunion to call them so they can tell TU it's not being disputed.
I'm going for a VA loan, too. Every place I have called has said they wanted all disputes to be resolved. So, if you are still disputing, you will need it to be resolved before they approve you. I know how frustrating this is. I believe this is something they just starting doing a couple of months ago. I don't think it mattered last year. Something else just to make it harder to get a loan now.
