Depending on your real estate time horizon you will want to consider the option you have to foil credit thieves. You won't hear much about it from anyone who wants to lend you money, but you have some pretty cool new weapons available to protect your identity and your good credit.
Credit freezes allow you to lock down your information. Once you lock it down you will receive a "code" with which you can thaw your credit in the event you need to apply for credit. The big three credit companies are now all participating.
If the idea of freezing your credit is too severe consider Lifelock. This company protects you by setting credit alerts on your account with the credit bureaus and prompt them every 90 days to keep it current. They will work to remove your name from pre-approved credit card lists and order free reports for you each year. Let's say all someone still manages to get your information. They say that they'll do "whatever it takes" to get your identity repaired.
