It depends on a lot of things...

Will the home increase a lot in value? If it is really cheap now, getting a good investment while young is great idea. However, I've learned that depending on other people can really be a bad thing. Also, co-signing with your parents, unless you have a GOOD relationship with them is generally a bad idea, as it can turn into a fight later.

I'm glad you're taking Nebo into concideration while looking for a place. I know so many people who were very desperate to leave the nest and kicked thier dogs to the curb.

Best of luck!
