No go online and go directly to the credit agencies and look threw your credit. If there is anything in dispute they have online dispute forms. Do it yourself I have seen it raised over 100 points. I did it for my brother in-law and several friends it very easy. Then when you have the credit score you need. Then go to the Realtor, or look for you home. And, remember not to make any major new purchases, and try to pay own revolving debt.
I owned a mortgage company for 10 years.
