# The Low-Down-Payment Door: How Cambridge First-Time Buyers Can Use the FHA Duplex Limit to House Hack With Far Less Cash
Key Takeaways
•The direct answer: Commonwealth Standard reports that the 2026 FHA limit for a two-unit home in the Boston-Cambridge-Newton metro is $1,232,250. An FHA loan is a government-backed mortgage that allows a small down payment. If you live in one unit, you can put down as little as 3.5%.
•The myth: You need a quarter-million dollars saved to house hack in Cambridge.
•The reality: 3.5% down at that limit is about $43,129 before closing costs. But agent Peter Bouchie, citing MLS Pinergy data, puts the Cambridge multi-family median at $2,125,000, so most two-families sit well above the limit.
•The bottom line: Get fully underwritten. Target listings that have sat on the market. Search nearby cities too. Line up your lender, inspector and attorney before you tour.
Do You Really Need a Quarter-Million Dollars to House Hack in Cambridge?
Not for the down payment. Finding a building you can buy is the harder part.
House hacking means buying a two-family home, living in one unit and renting out the other. The rent lowers your monthly cost.
Commonwealth Standard notes that investment-property loans often require 15% to 25% down. On a $1,232,250 building, that is $184,838 to $308,063 in cash. At the FHA minimum of 3.5%, the same building needs about $43,129 down.
Amerisave's February 2, 2026 guide says FHA allows 3.5% down on buildings with one to four units. You need a credit score of 580 or higher and you must live in one unit.
FHA shrinks the cash problem in Cambridge. It doesn't shrink prices, so the search for a qualifying building is narrow.
What Does 3.5% Down on a Duplex Get You That a Condo Can't?
It gets you rent coming in.
A condo is simpler, but no second unit helps pay the bill. Repliers/MLSPIN data put the August 2026 median sold price at $1,660,000 for a single-family home and $750,000 for a condo. Across all property types (the "mixed" category, not duplex data), the median was $781,000.

A condo is the cheaper home at $750,000, but it brings in no rent.
Realtor.com's September 2026 snapshot, cited by Commonwealth Standard, puts Cambridge's citywide median rent at $3,596 a month. Treat that as an example; your actual rent depends on the unit's size, condition and location.
Be clear-eyed about the loan. At the FHA limit you'd still borrow about $1.19 million, according to agent Peter Bouchie. You'd also pay FHA mortgage insurance, a monthly fee charged because you put little money down. On top of that come taxes, insurance, repairs and the months when the unit sits empty. Rent covers part of your cost; it isn't free housing.
Before you make an offer, get answers in writing from your lender:
•How much of the projected rent will count toward my income?
•What is my all-in monthly payment?
Ask for a quote for a regular (non-FHA) loan on the same building, on the same day. Then compare the cash needed at closing and the monthly payment.
What Are the Strongest Arguments Against This?
First objection: "Most Cambridge duplexes cost more than the FHA limit."
This objection is correct. With a $2,125,000 multi-family median per Bouchie's MLS Pinergy figures, most Cambridge two-families can't be bought with this loan. Inside Cambridge, expect few options under the $1,232,250 limit Commonwealth Standard reports.
Your realistic options are:
•Older or smaller buildings.
•Homes that need work.
•The same search in nearby cities covered by the same metro limit.
Second objection: "Low cash at closing doesn't mean affordable."
This one is also true. You'd borrow about $1.19 million (Bouchie). That payment, plus FHA mortgage insurance, will be well above the payment on a $750,000 condo, the August median in the Repliers/MLSPIN data.
The rent from the second unit has to close most of that gap. Realtor.com's $3,596 citywide median is one benchmark. If the rent can't cover most of the difference after vacancy and repairs, the condo is the cheaper home. Run both scenarios with your lender before you offer.
Where Is the Door Actually Open This October?
Start with listings that have been sitting.
Repliers/MLSPIN's August data, charted below, show Cambridge had 8.3 months of supply across all property types, compared with 5.3 months for single-family homes.

|---|---|---|

| Months of Supply | Mixed | 8.3 months |

Months of supply is how long it would take to sell every listed home at the current pace. This is a citywide signal, not a duplex measure. More supply can mean more room to negotiate: a better price, help with closing costs, or a seller more open to FHA terms.
Realtor.com's September figures, covering all property types, show Cambridge homes sitting a median of 58 days. A seller who has waited nearly two months may be more flexible.
Run the same duplex search in Somerville, Medford and Watertown. Confirm with your lender that the address falls under the same Boston-Cambridge-Newton limit, and don't assume prices match Cambridge's.
Cambridge still has one big rental advantage: walkability. ApartmentGuide ranks Inman Square highest, with a Walk Score of 97. All of the top ten listed neighborhoods score 92 or above. Walkable locations like these tend to appeal to renters.

Who Should You Line Up Before You Tour?
FHA lowers the cash you need upfront. A Cambridge two-family still takes more planning than a condo.
•Lender: Get fully underwritten, not just pre-qualified. Being underwritten means the lender has checked your income, credit and documents. Confirm the two-unit FHA limit applies to your file. Ask whether the FHA appraisal could require repairs before closing.
•Inspector: Older Cambridge two-families can hide expensive problems. Check the heating system, roof, sewer line, wiring and shared utilities.
•Attorney: Cover four topics:
•Legal status: Confirm the property is a legal two-unit.
•Lead paint: If the building was built before 1978, ask what Massachusetts lead-paint rules you'd have to follow as a landlord.
•Broker fees: This matters when you rent out the second unit. NBC Boston reported that the state broker-fee law, effective Aug. 1, 2025, requires whoever hires the broker to pay the fee. Ask what penalties apply.
•Rent rules: Ask your attorney which local and state rental rules apply to your second unit today.
•Occupancy plan: Ask your lender how soon you must move in and how long you must live there.
Is This Really a Door for Cambridge First-Time Buyers?
Yes, but it is a narrow one.
The FHA limit doesn't make the typical Cambridge two-family cheap. It doesn't erase repairs, taxes, insurance or vacancy risk.
It does change the cash you need. Many investment-property buyers need $184,838 to $308,063 down. An owner-occupant may need about $43,129 before closing costs. That makes buying possible on far less savings. Whether you can afford it month to month depends on the rent.
If you want to house hack this October, don't chase every duplex. Find the few that fit the limit, model the rent against a condo payment, and move with a strong team.
