How do merchant bridge loans support real estate flips?

Merchant bridge loans (often called bridge or short‑term rehab loans in the real estate industry) give investors the fast, flexible cash needed to buy, renovate, and resell properties when timing matters. In my practice working with investors and small developers, I regularly see these loans turn an otherwise lost opportunity into a profitable flip — but only when underwriting, timelines, and exit plans are disciplined.

Below I explain how merchant bridge loans work for flips, the typical terms and costs you should expect in 2025, practical underwriting and exit strategies, tax implications, and a checklist to improve approval odds.

How merchant bridge loans differ from traditional mortgages

  • Speed: Bridge lenders can approve and fund in days to a few weeks; conventional mortgages usually take 30–60+ days.
  • Underwriting: Bridge loans are primarily asset‑based: lenders focus on the property’s value (usually the after‑repair value, or ARV) and the borrower’s exit plan rather than on long credit histories or qualifying income.
  • Term & cost: Bridge loans are short term (commonly 3–12 months for flips) and carry higher interest rates and fees than permanent loans.
  • Purpose: Designed as temporary capital for purchase and rehab — not long‑term financing.

These distinctions let flippers move quickly on below‑market buys or distressed properties that require immediate work.

Typical loan structure and economics (what to expect in 2025)

  • Loan-to-ARV (LTV or LTC): Most bridge lenders will lend 60%–75% of the after‑repair value (ARV) or 65%–80% of purchase price plus renovate costs, depending on the lender and market. Conservative lenders prefer 60%–70% of ARV.
  • Interest rates: Market ranges in 2025 generally run from about 8%–18% annualized, depending on lender risk appetite, borrower track record, and local market strength.
  • Fees and points: Expect 1–4 points (1%–4% of loan amount) in origination fees, plus closing costs and underwriting fees. Some lenders add servicing or draw fees during rehab.
  • Duration: Typical terms are 3–12 months for flips; extensions are possible but costly.
  • Payment structure: Interest‑only monthly payments are common, with principal due at sale or refinance. Some lenders require interest reserve funds to be held back to cover payments during rehab.

Example: A $300,000 merchant bridge loan at 10% interest with 2 points ($6,000) and a 6‑month term would carry roughly $15,000 in nominal interest (10% × $300k × 0.5 year) plus the $6,000 origination fee — a financing cost that must be covered by project profit.

How lenders underwrite flips (what they look for)

  • After‑Repair Value (ARV): A realistic appraisal or broker price opinion is essential. Lenders stress‑test ARV assumptions.
  • Exit strategy: Clear proof of resale plan and timeline. Some lenders require a signed listing agreement or demonstrated resale comps.
  • Renovation scope: Detailed budget, contractor bids, and a realistic schedule; many lenders want permits if the work needs them.
  • Borrower experience: Track record of successful flips improves terms (lower rates, higher LTV). First‑time flippers face stricter terms.
  • Title & liens: Lenders require clean title and will do a title search and insurance.

Practical exit strategies

  1. Sell the property after rehab (most common). Proceeds pay off the bridge loan and fees.
  2. Refinance to a permanent loan (bridge‑to‑permanent) if market conditions and borrower qualifications allow. Note: refinancing approval is subject to conventional underwriting.
  3. Pay off with cash from other sources — less common but viable for repeat investors.

Important: Don’t assume an easy refinance. If your plan depends on refinancing, confirm prequalification requirements early with a conventional lender.

Tax and accounting considerations (2025 guidance)

  • Short‑term flips are generally treated as ordinary business income, not long‑term capital gains, because the owner’s intention is resale (see IRS guidance on business income and sales). This means profits are typically reported on Schedule C (or the applicable business return) and may be subject to self‑employment tax. (IRS: see Self‑Employment Tax and Publication pages at irs.gov).
  • Keep detailed records of acquisition cost, hard and soft rehab costs, and selling expenses. Good bookkeeping reduces audit risk and clarifies taxable profit.
  • Interest and certain loan costs may be deductible as business expenses when the flip is a trade or business; consult a tax professional for specifics.

Always verify how your particular transactions should be reported; consult a CPA or tax attorney because tax treatment varies by frequency, entity structure, and intent.

When a merchant bridge loan is the right tool

  • When a property requires fast close and immediate rehab to capture a price arbitrage.
  • When you have a clear, short rehab timeline and conservative ARV comps.
  • When a conventional loan would be too slow or would require repairs before funding.
  • When you can cover higher financing costs and still project a satisfactory profit margin after fees and taxes.

When it’s not right: If your timeline is uncertain, your ARV comps are thin, or you cannot tolerate high monthly interest costs, consider alternative financing or partnerships.

Common mistakes and how to avoid them

  • Underestimating rehab costs and timeline. Build a 10%–20% contingency into budgets.
  • Over‑reaching on ARV. Use conservative comps and an independent appraisal when possible.
  • Failing to secure a realistic exit. Have a backup exit (e.g., cash reserves or bridge‑to‑permanent contingency) before closing.
  • Not accounting for carrying costs (taxes, insurance, utilities, loan interest). These reduce profit quickly.
  • Relying on a refinance that isn’t prequalified. Verify refinance criteria with a permanent lender early.

Checklist to improve approval odds

  • Clean title and basic property due diligence completed.
  • Clear scope of work with contractor bids and a timeline.
  • Realistic ARV comps from recent similar sales.
  • Proof of funds for down payment and contingency (or a strong credit profile and track record).
  • Business plan or one‑page project summary with exit strategy.
  • Permits or permit plans if required by local jurisdiction.

How merchant bridge loans compare to hard‑money loans

“Merchant bridge loan” is often used interchangeably with “hard‑money” in the flip market. Both are asset‑backed, short‑term loans from private/non‑bank lenders. Differences are mostly marketing and in nuances of repayment structure: some lenders who call their product a merchant bridge loan will offer more flexible draw schedules or working capital features for experienced investors.

Final professional tips

  • Run conservative numbers: assume the higher end of interest and fees, and the lower end of ARV comps, when stress‑testing a deal.
  • Build relationships with at least two bridge lenders to compare pricing, speed, and willingness to structure draws for rehab.
  • Keep clear records and involve your CPA early to model post‑tax profits.

Author note: In my 15+ years advising investors, the best flips funded with bridge capital were those where the lender and borrower agreed early on scope, contingencies, and a conservative exit — and where the borrower respected the lender’s timelines and draw requirements.
