The quick read: Four lender types write multifamily bridge loans in Charleston, SC: private debt funds and mortgage REITs, bank balance-sheet lenders, agency-affiliated bridge-to-agency programs, and private or hard money bridge lenders. They differ on what value they lend against, how they price over SOFR, what you must prove to extend, and whether you sign a personal guarantee. Freddie Mac's published Value-Add product sheet (04/25) sets an 85% as-is / 75% as-stabilized maximum LTV, a 1.15x / 1.30x minimum DCR, floating-rate interest-only pricing with no required rate cap, a three-year term with up to two 12-month extensions, a 1% exit fee, a 0.5% upfront fee and non-recourse financing, so this guide anchors its dated numeric grids in both that product sheet and a public REIT's SEC filing. The Charleston-specific variable is supply. Census Bureau permit files show units permitted in 5+ unit buildings in the Charleston-North Charleston metro fell from a 2022 peak of 3,128 to 2,073 in 2023, then 1,437 in 2024 and 1,337 in 2025, and that shrinking pipeline of new competing units is what a lease-up or value-add bridge is tested against.
Which lenders write multifamily bridge loans in Charleston, SC?
Four lender types write multifamily bridge loans on Charleston and North Charleston apartments: private debt funds and mortgage REITs, bank balance-sheet lenders, agency-affiliated bridge-to-agency programs, and private or hard money bridge lenders, and each one sizes the same property against a different value and a different exit test.
Debt funds and mortgage REITs lend against the business plan, funding renovation dollars in draws and sizing the loan to the value the property should reach once units are turned and leased. Bank balance-sheet lenders lend against what the property earns today, usually with recourse, and often price around a deposit relationship. Agency-affiliated bridge-to-agency programs fund light renovation inside a defined per-unit budget with a planned refinance into a permanent agency loan. Private and hard money bridge lenders take the deals the others pass on, such as a short contract deadline, a heavily vacant building or a sponsor without a long track record.
For how the product works in general, see our guide to multifamily bridge loans and the bridge loan program page.
How do the four lender types compare on leverage, rate, extensions and recourse?
The four lender types compare most clearly on four terms: the value the loan is sized against, the spread charged over the SOFR index, the conditions you must meet to extend, and whether the loan carries a personal guarantee, and only the debt fund or mortgage REIT row below comes from a published, dated filing.
Lender-type comparison for a Charleston apartment bridge loan (debt fund/REIT row: one NYSE-listed REIT's SEC filing, as of June 30, 2026; agency row: Freddie Mac's published Value-Add product sheet, 04/25, which sets an 85% as-is / 75% as-stabilized maximum LTV, a 1.15x / 1.30x minimum DCR, a three-year term with up to two 12-month extensions, and a 1% exit fee; other rows: set lender by lender, no public dated grid):
| Lender type | Leverage basis | Rate basis | Extension tests | Recourse |
|---|---|---|---|---|
| Private debt fund or mortgage REIT | Sized on as-is value at closing, with a future-funding tranche for renovation measured against a projected stabilized value; one NYSE-listed REIT reported a 69.33% average as-is LTV at origination as of June 30, 2026 (SEC filing exhibit) | Floating over 30-day term SOFR; the same REIT reported a weighted average note rate of SOFR + 3.30% as of June 30, 2026 (SEC filing exhibit) | Set in the loan agreement; usually tied to renovation progress, occupancy or a coverage test, plus a fee | Usually non-recourse with carve-out guarantees; confirm per term sheet |
| Bank balance-sheet bridge | As-is value and in-place coverage, often priced with a deposit relationship | Floating over SOFR or prime | Covenant tests set by the bank's credit committee | Usually full or partial recourse |
| Agency-affiliated bridge-to-agency (e.g., Freddie Mac Value-Add) | Short-term financing for light renovation, $10,000 to $25,000 per unit, with 50% of the budget required on unit interiors and up to 20% budget flexibility without additional approval; as-is baseline max 85% LTV / min 1.15x DCR, as-stabilized baseline max 75% LTV / min 1.30x DCR, both subject to market adjustment, per Freddie Mac's published product sheet | Floating-rate, interest-only; no interest rate cap purchase required; sized on a 7-year sizing note rate, per the same product sheet | Three-year term with one 12-month extension at borrower's request and one optional 12-month extension at Freddie Mac's discretion; 12-month lock-out, then a 1% exit fee (waived if refinanced with a qualified Freddie Mac Conventional loan), per the same product sheet | Non-recourse, per Freddie Mac's published product sheet; a 0.5% nonrefundable upfront fee and generally 15% cash equity apply |
| Private or hard money bridge | As-is value, usually at a lower advance | Higher coupon priced for asset risk | Negotiated; often a fee per extension | Often recourse |
Agency renovation budget: $10,000 to $25,000 per unit, with 50% of the budget required on unit interiors and up to 20% adjustment allowed without additional approval, per Freddie Mac's published Value-Add product sheet.
Agency rate structure: floating-rate, interest-only, with no interest rate cap purchase required, per the same product sheet.
Agency recourse: non-recourse, per Freddie Mac's published Value-Add product sheet, which also sets an 85% as-is / 75% as-stabilized maximum LTV, a 1.15x / 1.30x minimum DCR, a three-year term with up to two 12-month extensions, a 1% exit fee and a 0.5% upfront fee.
What does a public lender's SEC filing show about pricing in a Charleston deal?
One public window into floating-rate multifamily loan pricing is a lender's SEC filing: one NYSE-listed real estate investment trust reported, as of June 30, 2026, a commercial real estate loan portfolio approximately 91.7% collateralized by multifamily assets, a weighted average note rate of SOFR plus 3.30%, and a 69.33% average as-is loan-to-value at origination.
Read that figure for what it is. It describes one lender's portfolio of loans closed over several years, not a quote for a new Charleston deal, and the filing does not label the loans bridge loans. A weighted average blends loans of different vintages and leverage levels, and the filing's footnote says the 69.33% LTV figure "has not been updated for any subsequent draws or loan modifications," so it says nothing about how much future-funding a renovation loan carries today. What the filing does show is the shape of the product: floating rate, 100% indexed to 30-day term SOFR, with a 9-month weighted average remaining initial term that reaches 18 months only if borrowers exercise every extension.
Index: 30-day term SOFR, per the filing.
Overnight SOFR on October 1, 2026: 3.87%, per FRED (FRED publishes the overnight rate, not 30-day term SOFR).

How does Charleston-area apartment permit supply affect the lease-up environment?
Charleston-area apartment permit supply affects the lease-up environment because debt funds, mortgage REITs and agency-affiliated lenders size a value-add or lease-up bridge partly on the rent your units will command, and fewer new buildings delivering nearby means less competition for the same renter, which is the direction Charleston's permit count has moved since 2022.
Units permitted in 5+ unit buildings, Charleston-North Charleston metro (Census Bureau Building Permits Survey annual files; CBSA code 16700):
| Year | Units permitted in 5+ unit buildings | Census source file |
|---|---|---|
| 2021 | 2,342 | Metro annual file, ma2021a.txt (file dated April 27, 2022) |
| 2022 | 3,128 | Metro annual file, ma2022a.txt (file dated April 2, 2024) |
| 2023 | 2,073 | Metro annual file, ma2023a.txt (file dated April 24, 2024) |
| 2024 | 1,437 | CBSA annual file, cbsa2024a.txt (file dated May 1, 2025) |
| 2025 | 1,337 | CBSA annual file, cbsa2025a.txt (file dated May 14, 2026) |
Two cautions apply. First, the Census Bureau publishes 2021 to 2023 in a metro series that ends in 2023 and 2024 onward in a CBSA series that begins in January 2024, so the two halves of the table come from different file series, though both carry the same CBSA code, 16700. Second, a permit is an authorization, not a delivery: units permitted in any given year reach the leasing market over the following years, and some permitted projects are never built.
For a bridge lender, a shrinking permit pipeline is generally favorable for an in-progress lease-up, because fewer new units are competing for the same renter by the time your as-stabilized rent is tested. It does not eliminate the test: buildings permitted in the 2021–2022 peak are still delivering through 2024–2026, so name the specific competing properties within your renter's commute, their delivery dates and their asking rents in your own submission rather than relying on the metro-wide trend alone. For local market context, see the Charleston market page.
What extension tests should a Charleston borrower expect on a bridge loan?
Extension tests are the conditions a Charleston borrower must meet to exercise a bridge loan's renewal option, and they commonly include no default, a performance threshold such as a minimum debt yield or coverage ratio, a fee, and sometimes a renewed interest rate cap or a paydown of principal.
The REIT filing cited above shows why extensions matter: it reports a 9-month weighted average remaining initial term that becomes 18 months only "if all extensions are exercised by the borrowers." An extension option is only as good as the test attached to it. If renovation runs late or lease-up is slower than planned, a property that misses the performance test can face a forced paydown just when its cash is tightest, and the Freddie Mac Value-Add product sheet, while confirming the loan is short-term and non-recourse, sets its own extension test as one 12-month extension at the borrower's request plus one optional 12-month extension at Freddie Mac's discretion, with a 1% exit fee after a 12-month lock-out (waived if refinanced into a qualified Freddie Mac Conventional loan).
Ask every lender three questions before you compare proceeds:
- What exactly must be true on the extension date: renovation completion, occupancy, coverage, or a debt yield?
- What does each extension cost, and is it a fee, a spread step-up, or both?
- If I miss the test, is the remedy a paydown, a cash sweep, or a default?
What does an illustrative Charleston value-add deal look like at today's SOFR?
An illustrative Charleston value-add deal shows how the index, an assumed spread and a renovation budget inside Freddie Mac's published per-unit band fit together before any lender quotes, and every figure below is illustrative except the dated SOFR level from the Federal Reserve.
Illustrative property: 104 units built in the late 1980s, about 90% occupied.
Illustrative (our arithmetic): a $10,400,000 purchase for 104 units is $100,000 per unit.
Illustrative (our arithmetic): a $1,560,000 renovation budget across 104 units is $15,000 per unit, inside Freddie Mac's published $10,000 to $25,000 per-unit band.
Floating-rate index: SOFR was 3.87% on 2026-10-01, per the Federal Reserve Bank of St. Louis FRED series.
Illustrative (our arithmetic): SOFR of 3.87% plus an illustrative 3.30% spread (the REIT filing's weighted average, not a Charleston quote) is a 7.17% coupon.
Illustrative (our arithmetic), assuming an 80% advance, below the sheet's 85% as-is maximum: an $8,320,000 loan against the $10,400,000 as-is value.
Illustrative (our arithmetic): interest-only debt service at 7.17% on $8,320,000 is about $596,544 a year.
Every one of those figures depends on a lease-up or renovation premium holding through the extension date, which is why the extension test, not the opening coupon, decides whether this deal works.
When should a Charleston apartment buyer use a DSCR or construction loan instead of a bridge loan?
A Charleston apartment buyer should use a DSCR loan instead of a bridge loan once the property already covers its own debt service, and should use a construction loan instead when the plan is ground-up development rather than acquiring and renovating an existing building, because each product is priced and underwritten for a different stage of the deal.
A bridge loan is built for the gap between buying an under-performing or vacant property and reaching a stabilized, income-producing state; it carries a floating rate and a time-limited term because that gap is supposed to close. If your Charleston property already rents at or near market and covers its payment today, our guide to DSCR loans in Charleston, SC covers the long-term, cash-flow-based alternative. If your plan is new construction rather than acquiring an existing building, see our guide to financing small apartment construction in Charleston, SC, which uses a different draw schedule and completion test than any bridge product in the table above.
What should a Charleston apartment buyer send to get bridge term sheets?
A Charleston apartment buyer should send a rent roll, a trailing 12-month operating statement, a per-unit renovation budget, the as-stabilized pro forma and a stated exit, because those five documents let every lender type size the as-is and as-stabilized case on the first read. YieldStack is a commercial mortgage brokerage, not a lender.

Every credit decision is made by the lender; YieldStack arranges the introductions and negotiates on the borrower's side, and no loan, rate, or closing is guaranteed.
- Rent roll: unit by unit, with lease dates, in-place rent and concessions.
- Trailing 12-month operating statement: plus the prior year if the property recently changed hands.
- Renovation budget: per-unit scope, contractor bids and the schedule of units offline.
- As-stabilized pro forma: the renovated rent you expect and the competing supply nearby that could undercut it.
- Exit plan: the permanent loan, DSCR refinance, or sale you expect, sized to the as-stabilized value.

The bottom line
Debt funds, mortgage REITs, bank balance-sheet lenders, agency bridge-to-agency programs and private bridge lenders all write Charleston apartment bridge loans, but they size, price and extend differently, and Freddie Mac's own Value-Add product sheet confirms the renovation band and non-recourse structure, with an 85% as-is / 75% as-stabilized maximum LTV, a three-year term with up to two 12-month extensions and a 1% exit fee. In this metro the deciding variable is supply: 5+ unit permits fell from a 2022 peak of 3,128 to 1,337 in 2025, so underwrite the as-stabilized rent against a shrinking pipeline and negotiate the extension test first.
