There are several methods to increase one's credit score. A client of mine was in the same situation 3 months ago and we are now looking to make an offer on a property. I have resources and people who specialize in advising and assisting people in your circumstance. If you are interested in a proffessional to guide you I can help.

Repairing your credit score starts with understanding why your credit score is what it is. In some cases, it is very simple, late payments lower your credit score and the more recent they are the more damaging it will be. However, there are other components to your credit that will impact your score such as your balance-to-limit (or debt to high credit) and more importantly your credit history. In addition to being a real estate professional, I am also a licensed mortgage loan originator in the state of NY and have been for the last 13yrs. I would be happy to speak with you about reviewing your credit report while discussing options and potential strategies. Please contact me directly.
