Where You Can Co-Buy at Different AMIs in Greater Boston

Everyone thinks homeownership is impossible, but what if by working together it was attainable today?

This table answers the question: if you're a moderate income earner, where you buy a home in Greater Boston? Each row is a town. "Median Price" and "Monthly Cost" columns come straight from our own sales data - what homes actually sold for and what owning one costs per month. The AMI columns (60%, 80%, 100%) are income limits set by HUD for a one-person household in our region, converted into a monthly housing budget - basically, the most a single person at that income level can safely spend on housing. The "Locked Out / Unlocked" columns compare the two: if the monthly cost is higher than the income limit allows, that person is locked out of buying alone. Once you add co-buyers, the cost per person drops, and in most towns it drops enough to become affordable.

How We Calculated the AMI Income Ceilings

60% AMI
$1,680/mo
$72,000 × 28% ÷ 12
80% AMI
$2,240/mo
$96,000 × 28% ÷ 12
100% AMI
$2,800/mo
$120,000 × 28% ÷ 12

Why the same income limit applies to every town: HUD sets this income limit once per metro area, not per town - all 20 towns above sit inside the same Boston-Cambridge-Quincy HUD area, so the income limit doesn't change, only the home prices do. The 28% is the standard "don't spend more than this on housing" rule lenders use. Figures here are for a single person (1-person household), not a family of four - a more realistic comparison since many buyers coming to us are individuals, not families.

What every row assumes

Financing
20% down, 6.5% interest, 30-year term.
Carrying costs
1.15% property tax, 0.5% insurance, 1% annual repairs.
Cost per buyer

AMI income limits
MHP 2026 Income Limits PDF (mhp.net), Boston-Cambridge-Quincy, MA table, 1-person household: $72,000, $96,000 and $120,000 per year.
Affordability ceiling
Each AMI income figure converted to a monthly housing budget using the standard 28% front-end debt-to-income ratio: Ceiling = Annual Income × 0.28 ÷ 12.
Why 28%?
28% is the standard "front-end" debt-to-income ratio lenders use to evaluate mortgage affordability — the maximum share of gross monthly income a household should spend on housing costs to be considered a safe loan. It is a widely used underwriting benchmark, not a Restored Living assumption.
Property data
Median price per bed and listing counts from the Restored Living own_town_median table; median rent per bed from the rent_by_town table.
Market selection
20 towns selected as key Greater Boston markets — not the full ~345-town dataset. Can be expanded on request.
Household size
AMI figures used are for a 1-person household (not 4-person), reflecting that many buyers coming to Restored Living are individuals rather than families, and that a 4-bedroom property is shared by multiple co-buyers rather than occupied by one household.
