We were looking at a mid-market value-add that needed capital now and a permanent loan in a few months. The sponsor could either stretch for a permanent mortgage and miss rehab timing, or take a short-term product that lets them execute the plan. That tradeoff — time versus fit — is the core of choosing among the types of commercial real estate loans.
The core idea
There’s no single “best” commercial loan. Each product exists to solve a business problem: buy, build, bridge, or run. Match the loan’s mechanics to the asset’s cash-flow timing and your exit plan. Choose based on timing, risk, and what lenders underwrite — DSCR, LTV, and NOI — rather than the lowest headline rate.
1) Permanent / commercial mortgage loans — for stabilized assets
What they are: Long-term loans that sit on the property as the primary debt. Banks, credit unions, and life companies are the typical providers. Use these when the asset already generates predictable income.
When to use: Stabilized multifamily, industrial, or well-leased office and retail. If you have steady NOI and want predictable debt service, this is the right lane.
What to watch for: Underwriting will focus on DSCR, LTV, and historical occupancy. Don’t force a permanent mortgage on a property that needs heavy rehab — you’ll either fail underwriting or face restrictive covenants. If your plan needs time to lift rents or fix operations, layer a short-term product first.
2) Bridge loans — solve short-term timing gaps
What they are: Short-term loans meant to bridge a timing or execution gap. They’re common for value-add deals that refinance into a permanent mortgage after stabilization; for a deeper look, see bridge loan strategies for value‑add deals.
When to use: You need speed, flexibility, and a clear short runway. Bridge loans are also common when you have a 1031 or other timing-sensitive closing obligation. They typically run 6–36 months.
What to watch for: Higher cost and prepayment provisions. Don’t treat a bridge as a cheap long-term loan — use it to complete a plan and exit to permanent financing.
3) Construction loans — build or gut-rehab the asset
What they are: Interest during construction is typically charged only on drawn amounts; lenders release funds in draws tied to milestones. Construction loans usually convert to permanent loans or are paid off at stabilization.
When to use: Ground-up development or heavy rehabilitation that requires staged disbursements and construction oversight.
What to watch for: Budget discipline and a realistic draw schedule. Lenders expect contingencies and a plan for cost overruns. If margins are tight, build reserves or work with a lender familiar with your GC and subcontractors.
4) Lines of credit and working capital — operational liquidity
What they are: Revolving credit lines, secured or unsecured, used for operational needs — tenant build-outs, seasonal shortfalls, or unexpected capex.
When to use: When the issue is cash-flow timing, not the capital structure of the asset. A line keeps operations running without breaking up long-term debt.
What to watch for: Don’t use working capital to paper over a structural NOI shortfall. Unsecured lines cost more and are riskier if your operating income dips.
5) SBA loans — owner-occupied and small-business CRE
What they are: Government-backed programs that favor owner-occupied properties and small businesses. The SBA 504 is a common fit for owner-occupied small-business CRE under $5 million.
When to use: If you own and operate the business on the property and want lower down payment or longer fixed-rate options than some conventional products.
What to watch for: SBA loans have program rules and documentation needs. They’re a good fit for owner-operators but not for passive investment properties where the business is not owner-occupied.
6) CMBS / conduit loans — institutional, scale plays
What they are: Bonds backed by pools of commercial mortgages. CMBS can provide long-term, non-recourse financing for larger deals.
When to use: Institutional-scale acquisitions or refinances where loan size and sponsor profile match conduit market expectations.
What to watch for: Servicing and special-servicing provisions. CMBS underwriting is tight and less flexible on workouts compared with local bank relationships.
7) Hard money / private debt — speed and underwriting flexibility
What they are: Private lenders who underwrite more to the asset and exit than to sponsor credit. They are fast and flexible, but costlier and often short-term.
When to use: Rapid acquisitions, deals traditional lenders won’t touch, or sponsor-specific needs where speed is worth the premium.
What to watch for: Cost and covenants. Private debt is a transaction tool, not the foundation of your long-term capital stack unless you’ve planned for the economics.
How lenders look at deals (and what you should prepare)
Lenders universally focus on the same things: debt service coverage (DSCR), loan-to-value (LTV), and net operating income (NOI). For a primer on underwriting mechanics, see what underwriting looks for (lender vs. investor) and our commercial real estate underwriting checklist. Bring clean financials, a clear pro forma tied to your business plan, and a realistic exit. If you’re asking for construction or bridge capital, show the timeline and the permanent lender or exit trigger.
Common mistake: handing a bank a pro forma that assumes immediate rent uplifts without a detailed execution plan. If rent bumps are central to your loan, lenders will ask for milestones and proof you can reach them.
Mini-case: the classic value-add bridge
Scenario: Sponsor buys an under-rented multifamily asset with a rehab plan that will take months to execute. The permanent market requires stabilized NOI to underwrite. The sponsor takes a bridge loan to fund acquisition and rehab, executes the value-add, then refinances into a permanent commercial mortgage once occupancy and rents stabilize.
Why it works: The bridge solves timing. It accepts a higher short-term cost in exchange for speed and flexibility. Then the permanent loan lowers debt service and locks long-term financing aligned to the stabilized cash flow.
Where deals fall apart: Sponsors try to stretch a permanent loan across the rehab window. Lenders pull the file or add expensive covenants. Or sponsors run out of contingency because they mis-scheduled draws. Prevent common mishaps by following best practices on how to keep due diligence from stalling a deal. If you plan to bridge, model the refinance step and stress-test the exit timing.
Practical lender-match rules
- If the asset is stable and cash-flowing, go to banks or life companies for long-term mortgages, and align your process to build repeatable acquisitions by following our guide to building repeatable commercial acquisitions.
- If you need speed and a short runway, talk to bridge or private lenders.
- If you’re building or doing heavy rehab, use a construction loan with draws tied to inspections.
- If you’re owner-occupier and small-scale, evaluate SBA 504 for better down payment and fixed options.
- If you need large non-recourse debt at scale, CMBS is a channel to consider.
Where a CRE-specific tool helps
When deals have tight timing and many moving pieces, you need a system to keep next steps from slipping. Use a CRE tool that tracks pipeline stages, surfaces prioritized follow-ups, and creates tasks when a deal moves stages (for example: Investment pipeline, Action Center, and deal-stage triggers). That prevents missed refinance windows and keeps the refinance-to-perm step visible.
- Keep your acquisitions and refinance timing visible across the team with an Investment pipeline and stage-based triggers.
- Work a prioritized daily queue so short-term bridge and construction tasks don’t get buried (Action Center-style follow-ups).

Key takeaways
- Match the loan product to timing: buy vs build vs hold.
- Use bridge loans for short-term gaps; don’t make them long-term fixes.
- SBA 504 fits owner-occupied CRE under $5 million — don’t force it on passive investments.
- Lenders underwrite DSCR, LTV, and NOI — bring clean, conservative pro formas.
FAQ
How long are bridge loans typically?
Bridge loans commonly run for 6–36 months and are designed to be temporary solutions until a permanent financing event.
When should I choose a construction loan over a bridge?
Choose construction loans for ground-up or heavy rehab projects that require draw schedules and progress inspections. Use bridge loans when you need short-term capital and the project is closer to stabilization.
Is CMBS better than bank debt?
CMBS can offer long-term, non-recourse financing at scale, but it’s less flexible on workouts and servicing. Banks are more relationship-driven and can be more flexible for sponsors who need operational leeway.
Can I use a line of credit to rehab a property?
Yes for small, tactical items. For major rehabs, lines of credit lack the draw oversight and structured release that construction loans provide. Use lines for working capital needs, not full project financing.
Before You Choose This, Check This:
- Confirm the timeline: will the asset be stabilized before permanent financing is available?
- Match lender appetite to deal size and asset type — don’t pitch a small rehab to institutional lenders.
- Stress-test your exit: can you refinance if rents or occupancy lag?
- Build contingencies into your draw schedule and budget for cost overruns.
- Don’t let the headline interest rate drive the decision — focus on covenants, prepayment, and fit.
