I'd also second Flourite and also Amethyst is another one I'd recommend.
Flourite is a protective crystal that also can help you to stay mentally clear. it is great in helping you to process things--and brings stability to your person as well.
Amethyst is another protective crystal that will also aid you in keeping a clear head.
Most importantly, carry citrine with you. Citrine is a powerful lucky stone, that will bring good luck your way and fortune. It is a great crystal for boosting mental clairity and confidence.
One other 'thing' to carry, if you can find it is a St. Joseph medial. Ask St. Joseph to help you find the right home for you at the right price. Yeah, he is a Catholic Saint, but no worries--he helps EVERYONE.
He is a helper to both buy and sell a home, though most people see him only for the selling of a home. If you can't get a medal (or a very small statue of him to carry on your person), just ask him to help you find the right home for you and at the right price.
Then, when you find that home, and get it, be sure to thank him for his help.
