The Housing Early Assistance Tool (HEAT) assists Service Members and their families in applying for housing Navy wide. HEAT allows Service Members and their families to get the housing application process started at one or more Navy installations online before or after they receive their permanent change of station orders. HEAT is available to any Service Member at all Navy installations. HEAT creates an easy user experience to connect with your destination. Spouses can use the application as well, needing only minimal information about their Service Member. A housing referral professional will be in touch within 2 business days.
