Frequently Asked Questions

Need help? No problem. Send us an inquiry and we will get back to you the same day.

01 What government services provide money for senior housing?
Several federal and state programs help cover the cost of senior housing, including Medicaid waivers, the VA Aid & Attendance benefit, Section 202 Supportive Housing for the Elderly, and state-specific assisted living subsidies. Eligibility varies by income, assets, and care needs.
02 How do you pick the homes you recommend?
We surface every licensed facility in our directory and rank them using publicly reported data — state inspection ratings, occupancy, staffing levels, citations, and price. We do not accept payment for placement in the explorer.
03 Do you help families that need Medicaid?
Yes. Assisting families who need Medicaid is important to us as it plays a crucial role in offering financial support to seniors confronting economic challenges. We would like to keep essential healthcare services accessible to all community members, irrespective of one’s financial circumstances.
04 How much does this service cost?
The Assisted Living Explorer is free to use. There is no charge to search, filter, compare, or contact a facility through our tools.
05 What services do you offer?
Beyond the explorer, we publish cost guides, in-depth facility profiles, regulatory inspection summaries, and a concierge service that helps families shortlist and tour facilities that fit their budget and care needs.
