Help me get my first home

My name is Crystal. I am a new RN. I dream of buying a home for me and my family. I am currently working 5-12 hour shifts a week. I am also working on improving my credit score. I just would appreciate any help that anyone would like to do to halp me get the downpayment together to buy the house we found. I have 2 children, a girl who is 12 and a boy who is 7. We are currently living in a rental that was not cared for appropriatly by the landlord or previous tenants. We just want to have a place that we can call our own. Thanks in advance for anything you can do. God Bless!!
