The Real Estate Adviser on Bankrate.com has answered an important question from a reader: Does a registered sex offender living in your neighborhood affect your home's value? The unfortunate answer is "yes."

One study found that a sex offender within one-tenth of a mile of your home makes your house sell for about 17% less than comparable homes without a sex offender in the neighborhood. If a sex offender is within two-tenths or three-tenths of a mile from your home, expect a 9% to 10% lower sales price. A separate study found that homes within one-tenth of a mile of a sex offender only sold for 4% less than comparable homes.

Even though there is a range of numbers presented, it's clear that the presence of a registered sex offender in your neighborhood will have an impact on the sale price of your home. It's no wonder. What parent would buy a house in close proximity to a registered sex offender? For most parents, that's too big a risk to take when you know your child will want to play outside during summer.

This is a good time to remind buyers to check registries to see if a sex offender is living in the neighborhood you're considering. If you can't locate a registry, check with the local police station for guidance on sex offender registration. You want to make an informed choice before you buy a home for your family.
