Short answer: A condo conversion is financed as a value-add bridge or light construction loan, typically sized at 70–80% of cost or 65–70% of the as-complete aggregate unit value, whichever is lower. The loan funds acquisition plus renovation on a draw schedule, and gets repaid through unit sales governed by a release price schedule in the loan documents. The master deed usually needs to be recorded before the first unit can be released.
Why conversions are their own category
A condo conversion is not a flip and it is not ground-up construction. You are buying an existing two-family, three-decker, or small multifamily building, renovating it, and — the part that actually creates the value — legally subdividing it into separately deeded units under Massachusetts General Laws Chapter 183A.
That legal step is where the margin comes from. A three-family in Somerville that trades at $1.6M as a rental building can be worth $2.4M as three individually deeded condos. Nothing about the structure changed. The ownership form did.
Lenders know this, which is why they underwrite conversions differently than a straight rehab. They are lending against a value that does not exist yet and cannot exist until a document gets recorded at the Registry of Deeds.
How lenders size a conversion loan
Most bridge and private lenders run three tests and take the lowest result:
Test Typical constraint
Loan-to-Cost (LTC) 70–85% of purchase price + hard costs + soft costs
Loan-to-As-Complete-Value 65–70% of aggregate retail unit value
Day-one advance 70–80% of purchase price, with the rest held back
The as-complete value is an aggregate number — the sum of what each finished unit sells for individually. Some lenders apply a discount to that aggregate (5–10%) to account for the fact that you are not selling all units on day one. Ask about this early. It moves your proceeds materially.
If you want the mechanics of these ratios in detail, see LTV, LTC, and LTARV explained.
The master deed is the gating item
Here is the sequence that trips up first-time converters:
- Loan closes. Lender records a mortgage against the whole property.
- Renovation proceeds on draws.
- Master deed and unit deeds are drafted, along with the declaration of trust and bylaws.
- Master deed is recorded, creating the individual units.
- Lender's mortgage now encumbers all units. Each sale requires a partial release.
Step 5 is the one to negotiate up front. Your loan documents should contain a release price schedule stating exactly how much of the loan gets paid down when each unit sells. If that schedule is not in the docs at closing, you are asking your lender for a favor at the moment you have a buyer under agreement and a closing date. That is a bad time to negotiate.
Standard release pricing runs 110–125% of the pro rata loan allocation per unit. On a $2.1M loan across three units, pro rata is $700K per unit; at 115%, you pay down $805K on the first sale. The lender gets de-levered faster than you sell, which is the point from their side. Push for the lowest release multiple you can get, and push for the last unit to carry no premium.
Municipal approvals vary more than people expect
Massachusetts has no statewide condo conversion approval process for small buildings — Chapter 183A governs the ownership form, not the permission to convert. What varies is local:
- Boston, Cambridge, Somerville, Newton, and several others have condo conversion ordinances triggered by tenants in occupancy. These impose notice periods, right of first refusal, and in some cases relocation payments. Timelines can run a year or more for protected tenants.
- Somerville in particular has strict tenant protections and a required conversion permit.
- Vacant, owner-occupied, or already-delivered-empty buildings move dramatically faster.
Lenders price this risk. A vacant building with a clean path is a normal deal. A building with three occupied units and elderly tenants in a city with an ordinance is a deal a lot of lenders will pass on outright, because their exit is legally blocked for a period they cannot control.
Deliver the building vacant if you can. It is worth negotiating into the purchase and sale.
What your submission package needs
To get a real quote instead of a polite maybe, put this in front of a lender:
- Purchase and sale agreement with the closing date
- Line-item construction budget — hard costs broken by trade, soft costs itemized separately, contingency of 5–10%
- Unit-by-unit ARV support — recent closed condo comps in the immediate submarket, not the town average
- Sources and uses showing exactly where equity is coming from
- Sponsor track record — prior projects with addresses, purchase price, cost, sale price, and dates
- Zoning and permitting status — is the unit count by-right, or does it need a variance or special permit?
- Occupancy status and any tenancy issues
- Architectural plans if the scope involves reconfiguration
By-right unit counts close. Discretionary approvals get conditioned or declined. If you need zoning relief, expect the lender to either wait for the decision or fund only acquisition until you have it in hand.
Typical terms in the current market
- Rate: floating, commonly in the low-to-mid double digits for private/bridge capital on small conversions
- Origination: 1.5–3 points
- Term: 12–24 months with extension options
- Interest: on drawn balance only, on most well-structured deals — avoid full-balance accrual if you can
- Recourse: full recourse with a personal guarantee is standard below $10M
- Extension fee: 0.25–0.50% for a 3–6 month extension
Where sponsors lose money is on unfunded costs. If your budget is $600K and your lender funds $480K of it, that $120K gap comes from your pocket on top of your down payment. Model that before you sign a P&S.
The exit
Two exits work: sell the units, or refinance a portion into long-term debt and hold them as rentals.
If you plan to hold, tell the lender up front, and start conversations about the takeout early. A converted condo unit that is leased can typically be refinanced with a DSCR loan based on rent rather than personal income. If you plan to sell, the release schedule is your whole financial model — one unit selling slowly can push you into extension territory.
FAQ
How long does a condo conversion take in Massachusetts? For a vacant two- or three-family with a straightforward scope, six to twelve months from acquisition to first unit sale. Occupied buildings in cities with conversion ordinances can add a year or more.
Can I finance the conversion costs, or only the purchase? Both. Conversion loans typically fund acquisition on day one and renovation through draws as work is completed and inspected.
Do I need the master deed recorded before closing the loan? No. Most lenders close against the undivided property and require the master deed to be recorded before the first partial release.
What credit score do I need? Most private construction and bridge lenders want 660+, with 700+ getting better pricing. Track record and liquidity matter more than the score itself.
How much cash do I need? Plan on 20–30% of total project cost, plus closing costs, plus reserves. Lenders also want to see post-closing liquidity — often 6–12 months of debt service.
