Getting a mortgage loan will depend on how long ago the judegement was paid off and how well you have managed your credit since paying off the judgement.
I had a client who had a judgement in the past,but due to the length of time the judegment had been paid off and how well he handled his credit since paying the judgement off he was able to secure a mortgage with a good rate and terms.
You should consult a lender for a pre approval, there will be no charge to you. As part of the pre approval process the lender evaluate your credit report and your income to determine if you are able to get a mortgage loan.
Best of Success to You!
