San Francisco did not raise the transfer-tax rates with Proposition J. It changed which distressed transfers get to avoid them.
Beginning March 1, 2027, a foreclosure or deed in lieu involving a five-unit apartment building, larger mixed-use property, office building, hotel or industrial asset can carry the same 0.5% to 6% transfer-tax schedule applied to other taxable transfers. Residential and mixed-use properties with fewer than five residential units keep the foreclosure exemption. Ordinary arm’s-length sales already subject to transfer tax do not receive a new rate.
What Proposition J changes
San Francisco has historically exempted a transfer to a lender caused by foreclosure, or made in lieu of foreclosure, up to the unpaid debt. Proposition J’s official measure text removes that exemption for most property other than small residential and mixed-use buildings.
| Property or transaction | Prop J treatment | Practical point |
|---|---|---|
| Residential property with 1–4 units | Foreclosure exemption remains | A single-family home, condo, TIC interest, duplex, triplex or fourplex is not pulled into the new rule solely by Prop J. |
| Mixed-use property with 1–4 residential units | Foreclosure exemption remains | Confirm the recorded use and legal unit count rather than relying on a marketing description. |
| Residential or mixed-use property with 5+ units | Foreclosure exemption removed | Model transfer tax if title may move to the lender through foreclosure or a deed in lieu. |
| Commercial, industrial and other covered property | Foreclosure exemption removed | The fair-market-value tax can materially reduce recovery on a distressed loan. |
| Ordinary purchase from the owner | No new rate created by Prop J | The existing transfer-tax schedule and any other applicable exemption or reduction still control. |
| Purchase of a loan without a property transfer | Prop J is aimed at the later real-property transfer | The note price should still reflect the tax if foreclosure or a deed in lieu is a realistic exit. |
The measure changes the foreclosure exemption in Business and Tax Regulations Code Section 1108.2. It does not eliminate every transfer-tax exemption or reduction.
The tax is based on property value, not the bargain price for the loan
The ballot question describes the tax as 0.5% to 6% of the property’s fair market value when a covered property transfers to a lender because of foreclosure or to avoid foreclosure. That distinction is the heart of the underwriting problem. Buying a distressed $15 million loan for $8 million does not make the building an $8 million property for transfer-tax purposes.
Assumes the label is the property’s taxable fair market value, the current general rate applies to the entire value, and no separate exemption or reduction applies.
| Assumed fair market value | Rate on entire value | Illustrative transfer tax | Calculation |
|---|---|---|---|
| $5M | 2.25% | $112,500 | $5,000,000 × 2.25% |
| $10M | 5.50% | $550,000 | $10,000,000 × 5.50% |
| $15M | 5.50% | $825,000 | $15,000,000 × 5.50% |
| $25M | 6.00% | $1,500,000 | $25,000,000 × 6.00% |
| $40M | 6.00% | $2,400,000 | $40,000,000 × 6.00% |
San Francisco uses the rate for the applicable tier on the entire taxable value, not only the value above the threshold. The statutory schedule is expressed per $500 or fraction.
The cliff at $10 million is especially important. A covered property at $9,999,999 is in the 2.25% tier, while a $10 million property is in the 5.5% tier. The difference is roughly $325,000 even though the assumed value changes by only $1.
How the tax changes a distressed-property bid
In our investment underwriting, I separate the cash flow from the appreciation story. Proposition J belongs in the cash-flow and basis analysis because it is a transaction cost you can identify before taking title. It should not be waved away with an assumption that future market appreciation will cover it.
| Line item | Calculation | Amount |
|---|---|---|
| Assumed fair market value | Property-specific estimate | $15,000,000 |
| Prop J transfer tax | $15,000,000 × 5.5% | −$825,000 |
| Legal, carry and stabilization reserve | Illustrative input | −$750,000 |
| Required margin and downside reserve | Illustrative input | −$1,500,000 |
| Maximum all-in basis before other costs | $15,000,000 − $825,000 − $750,000 − $1,500,000 | $11,925,000 |
A teaching example, not a valuation or bid recommendation. Replace every input with property-specific estimates and include senior liens, taxes, tenant obligations, capital work, financing and disposition costs.
The $825,000 does not automatically come out of one named party’s pocket in every workout. It does, however, come out of the economics. A lender may accept less for the loan, a bidder may reduce its price, or the parties may choose a different resolution. The tax is large enough that the deal team needs to assign it explicitly rather than leave it in “closing costs.”
Three paths that look similar but are not
| Path | What happens | Prop J question |
|---|---|---|
| Buy the building directly from the owner | The owner conveys the property in an ordinary sale | Prop J does not create a special new rate. Use the existing transfer-tax rules and the contract’s allocation. |
| Buy the loan and the borrower later pays or refinances | The debt changes hands, but title to the real property does not | The loan purchase itself is not the covered foreclosure transfer described by Prop J. |
| Buy the loan, then foreclose or accept a deed in lieu | Title moves because of foreclosure or to avoid it | For a five-unit-plus or other covered property after March 1, model the fair-market-value transfer tax. |
Real transactions can include entity interests, multiple liens, partial interests, bankruptcy, receivership or other facts that change the analysis. Confirm the exact transfer with title, escrow and counsel.
What to verify before buying a distressed note or property
- Confirm the legal residential unit count and current use. A four-unit mixed-use building and a five-unit mixed-use building fall on opposite sides of the stated exception.
- Get a defensible fair-market-value range. The tax base may not be the unpaid debt or the price paid for the note.
- Map the likely title path. A payoff, negotiated sale, deed in lieu, judicial foreclosure and trustee’s sale are not interchangeable events.
- Request a current title report and identify every senior lien, delinquent tax, assessment, judgment and recorded agreement.
- Ask title and escrow for a written transfer-tax estimate under the enacted language, including any claimed exemption or special reduction.
- Underwrite the tenant ledger, deferred maintenance and stabilization timeline. The transfer tax is only one part of the all-in basis.
- Stress-test debt service and reserves without depending on above-inflation rent growth or market appreciation.
Then connect the tax to the operating model. Our investment-property underwriting guide starts with recurring cash flow, and the San Francisco cap-rate calculator shows how a higher all-in basis reduces the going-in yield even when NOI stays the same.
What the election result means right now
As of November 4, KQED’s election page reported 151,460 yes votes and 39,119 no votes, or 79.4% approval, and listed Proposition J as passing. The final canvass and certification were still pending when this article was published. The measure text sets March 1, 2027 as the start date, so there is time to update models and closing checklists before the new treatment begins.
I would not rush a foreclosure simply to beat a tax date. I would make the timing, tax and alternative workout paths visible in the model, then choose the route that produces the best risk-adjusted recovery. A good distressed investment is still a cash-flowing asset bought at a defensible all-in basis. Proposition J simply adds one more large number that can no longer stay off the page.
Common questions
Did Proposition J increase San Francisco transfer-tax rates?
No. It removes the foreclosure exemption for most property other than residential and mixed-use properties with fewer than five residential units. The existing rate schedule still ranges from 0.5% to 6%.
Does Proposition J apply to a foreclosed single-family house or condo?
The measure retains the foreclosure exemption for residential properties with fewer than five residential units. Confirm the property’s legal classification and the current law before relying on an exemption.
Does a five-unit apartment building fall under the new rule?
Yes, the stated exception is for residential and mixed-use properties with fewer than five residential units. A covered five-unit transfer through foreclosure or a deed in lieu should be modeled with transfer tax beginning March 1, 2027.
Is the tax based on the loan balance?
The ballot question describes the tax as a percentage of the property’s fair market value. The prior exemption was limited by unpaid debt, but Proposition J removes that foreclosure exemption for covered properties.
Does buying a distressed note trigger the property transfer tax?
The measure addresses the later transfer of real property to a lender because of foreclosure or to avoid foreclosure. Buying the debt without a transfer of title is a different event, although the note price should reflect a possible future tax.
When does the change start?
The measure text specifies March 1, 2027. Final election certification was still pending when this article was published, although preliminary results showed overwhelming approval.
Methodology
The article applies the current general San Francisco transfer-tax rate for the entire assumed fair market value: 2.25% from $5 million to under $10 million, 5.5% from $10 million to under $25 million, and 6% at $25 million or more. Chart values are value multiplied by the applicable rate and assume no other exemption or reduction. The $15 million underwriting table subtracts $825,000 of transfer tax, an illustrative $750,000 legal/carry/stabilization reserve and an illustrative $1.5 million margin/downside reserve. Election totals are preliminary November 4 results, not a certified statement of vote.
