State by State: The Ceiling, the Window and the Floor
Everyone knows Affordable Housing has a limit on how much you can earn. Almost nobody counts what is left once the property also asks you to prove two to three times the rent. This is that arithmetic for all 2,623 income limit areas in the 50 states and D.C., grouped by state, with the household, the income, the affordability level and the income screen all in your hands.

Finding Where You Stand in Affordable Housing
Everyone knows Affordable Housing has a limit on how much you can earn. Almost nobody knows the property will also ask you to prove a minimum, because rent in a rent-restricted home is set by a published table rather than by what the resident earns. Set your household and your income, see every level at once, and find out what to ask before you apply.

Income Eligibility, Tenant Screening, and Who America's Affordable Housing Reaches
Older adults are the fastest growing group among people experiencing homelessness, and 42 percent of HUD-assisted households. So how much of the housing being built can they actually rent? We ran one person on the average Social Security benefit against every income limit area in the country. At the level most new affordable homes are built, the answer is none of them without assistance attached.

Creating a Parallel Pathway for the Affordable Housing We Already Have
America did not simply declare affordable housing valuable. It manufactured an asset, defined the unit of production, set the compliance standard, and gave several parties a reason to participate. None of that machinery exists for the bedroom that is already built, already heated and already standing. This framework sets out what would have to be true to change that, and invites others to pressure-test it.

The Economics of Home Sharing, State by State
The rooms exist and the need exists. This piece answers the next question: what is connecting them worth? Four national figures size the opportunity, then two calculators put it in your own terms. The State Math prices what the older-adult housing shortfall costs a state and what home sharing keeps from being spent. Your Household Math shows what a match is worth inside one household's budget.

America's Older-Adult Housing Gap, State by State
Every state in America has more spare bedrooms in homes owned by older adults than older renters who spend more for rent than is recommended. This interactive map puts a number on that gap for all 50 states and DC: the housing math, the cost burden on older renters and homeowners alike, and each state's aging-policy status. Hover over any state for a quick read, or click for the full picture.
White Paper · June 2026
Between Aging and Housing Policy
Older adults are the fastest-growing population experiencing homelessness, and the forces pushing them out of stable housing stack faster than the aging system or the housing system can answer alone. This systems brief shows where home sharing fits as preventive infrastructure, how it advances USAging's Doors to Housing priorities, and how shared infrastructure finally makes it practical to implement.

The Missing Middle of Aging Infrastructure
An older adult's move usually arrives with a single name on it: a fall, a death, a tax bill. The truer story is the five to ten years before, when two or three forces were already compounding. This paper proposes a frame for the years that lie between full housing stability and the first formal step of the aging-services continuum, and argues that this is where home sharing belongs.
