Real Estate Agent's Guide to Commercial & Multifamily

Your best investor client has been a machine — you’ve sold him three rental properties on conventional loans. Now he calls with the next one: a 12-unit apartment building, $2 million, strong rents. You want to help. And then you hit the wall you always hit at exactly this size, because at five units and up, none of your conventional financing works — and your instinct is to hand the whole thing to a commercial broker who’ll happily take the client, too.

Refer it away and you lose the commission and, often, the relationship you spent years building. Commercial and multifamily financing is how you keep both as your best clients graduate from single rentals to real portfolios. This guide explains what commercial financing does from an agent’s seat, where residential ends, and how connecting your client to the right lender lets you close a deal you thought wasn’t yours. It links to current terms on our commercial real estate financing page and commercial loans by asset class.

Where residential ends and commercial begins

This is the one line to memorize, because it defines the whole hand-off:

• 1–4 units = residential path. Conventional or DSCR. Your familiar world.
• 5+ units = still DSCR at Jaken Finance Group with no unit maximum — underwritten on the building’s NOI, not the buyer’s W-2. See 5–10 unit and 10+ unit apartment DSCR.
• Mixed-use, retail, office, industrial = commercial, regardless of unit count.

That fifth unit changes the file, not the product family. Agency loans die at four doors. Jaken Finance Group DSCR does not. The client who qualified on his fourplex can stay with you on a 12-unit — the lender just reads the rent roll and T-12 instead of a 1007 on one house.

The numbers that run a commercial deal — so you can talk credibly

You don’t underwrite these, but a few terms let you discuss a commercial listing like a pro and set expectations.

Net Operating Income (NOI) is the property’s income after operating expenses, before the mortgage — rents minus taxes, insurance, management, maintenance, and reserves.

Capitalization rate (cap rate) is NOI divided by value — the yield the building produces. Run in reverse, it sets value: NOI ÷ market cap rate = implied value. A $120,000 NOI at a 6% cap implies a $2,000,000 building.

Debt Service Coverage Ratio (DSCR) is NOI divided by the annual mortgage payments. Commercial lenders typically want 1.20–1.25+ — the income has to exceed the debt by a healthy margin.

The through-line: in commercial, the property qualifies. Your buyer’s experience and net worth matter, but NOI, cap rate, and DSCR are what get the deal approved. Point a buyer at the commercial property calculator to model it live.

The deals that are really commercial deals

Sort the deals you can’t place by cause. These aren’t dead — they’re commercial:

The deal is…	Commercial answer
A 5+ unit apartment building	Commercial multifamily, on NOI
A mixed-use building (retail down, apartments up)	Commercial, regardless of unit count
A retail strip, office, or industrial building	Commercial by asset class
Your investor client graduating from a fourplex to a 10-unit	The residential-to-commercial jump
A portfolio of rentals under one loan	Commercial blanket / portfolio
Your 5+ unit listing that needs a financeable buyer	Commercial financing widens the pool

If the property produces income and it’s bigger than a fourplex or isn’t residential, it’s a commercial deal — and a commission you can keep instead of refer away. Send the scenario over with the rent roll for a same-day read.

Rates, terms, and timelines to tell your client

You’re not quoting these, but they shape how you write the deal and set expectations:

• Down payment: typically 25–35% — commercial leverage is more conservative.
• Term & amortization: often a shorter term (5–10 yrs) on a longer amortization (25–30 yrs), sometimes with a balloon.
• Rate: set by asset class, DSCR, and the buyer’s strength.
• Close: 45–90 days — commercial appraisal and third-party reports take time. Write this into the contract.

The framing your client needs: commercial is slower and needs more down, but it unlocks a scale residential can’t touch — and it’s underwritten on the building’s performance, so a strong asset can carry a buyer whose personal income would never qualify residentially at that size.

A worked example you can walk a client through

Your client’s 12-unit building: 12 units at $1,500/month, 5% vacancy, operating expenses ~40% of income.

• Effective gross income: ~$205,000/year
• NOI (after ~40% expenses): ~$123,000
• Implied value at a 6% cap: ~$2,050,000 — supports the $2,000,000 price
• Loan at 70% LTV: ~$1,400,000; buyer brings ~$600,000 + reserves
• DSCR check: the lender confirms the NOI covers the payment at 1.20+
• Your outcome: you represent the buyer, close a $2M deal, and keep a client you’d have referred away

The value you add: you can show the client why the lender cares about NOI and what moves the deal — before underwriting surprises them. That’s advisory credibility no one else on the deal is providing.

How the deal closes, step by step

Stage	What happens
1	Buyer submits the rent roll, trailing-12 operating statements, price, and their financials
2	Lender builds NOI, tests DSCR, and sizes the loan
3	Term sheet / LOI issued; buyer deposits
4	Commercial appraisal and third-party reports ordered
5	Underwriting / loan committee review
6	Closing — 45–90 days from contract

The biggest delay is incomplete property financials. Coach your client to have a clean rent roll and trailing-12-month operating statements ready, and write a realistic escrow.

What your client will ask you — and how to answer

“Why do I need 30% down when I put 20% on my rentals?” Commercial leverage is more conservative and the loan is sized on the building’s cash flow, not just the price. More down often means better terms.

“They keep asking about NOI and cap rate — why?” Because the building’s income supports the loan. It’s the same instinct as a residential income check, just aimed at the property.

“Why is this so much slower than a house?” Commercial appraisals and third-party reports take weeks, plus there’s a committee. Plan on 45–90 days and you’ll never be caught off guard.

“Can I roll several rentals into one loan?” Yes — a blanket/portfolio loan does exactly that, common for an investor consolidating a scattered portfolio.

“Do I need a commercial agent, or can you represent me?” You can represent me on the purchase, often with a lender guiding the financing. Keep the deal — I brought it to you.

A second scenario: the mixed-use listing

Your seller has a $900,000 mixed-use building — two retail bays down, four apartments up — and buyers keep falling out because their lenders won’t touch it.

• Why it’s commercial: mixed-use is a commercial asset class regardless of the four residential units — a conventional lender won’t finance it
• The move: market it to investor buyers and position the blended income (retail leases + residential rents) to support the price
• The effect: you attract buyers who can actually finance it, instead of watching conventional buyers wash out
• Your outcome: a listing that kept dying in escrow finally closes

The lesson: unit count alone doesn’t classify a property. The moment there’s commercial space in the mix, it needs a financeable commercial buyer — and knowing that is what separates you from the agent who wastes months on buyers who can’t close.

Commercial vs. DSCR vs. conventional: a cheat sheet

	Commercial (5+ / mixed-use)	DSCR (1–4 unit)	Conventional
Property size	5+ units, or any commercial	1–4 residential units	1–4 residential units
Underwritten on	NOI / cap rate / DSCR	The property’s rent	The buyer (income/DTI)
Down payment	25–35%	20–25%	As low as 3–20%
Close	45–90 days	Faster than conventional	30–45 days
Best for	Investors scaling up	Rental investors	Owner-occupants

The pattern: your investor client’s journey runs conventional → DSCR → commercial as they grow. Hand off cleanly at each step and you keep the whole relationship across their entire career.

Keeping the five-plus unit listing alive

Listings at six units and up shrink the buyer pool to investors — most of whom won’t use conventional residential financing. Market the property with in-place rent roll and NOI snapshot in the OM; invite buyer’s agents to bring DSCR or commercial lenders, not FHA. Your listing isn’t “hard to finance” — it’s commercial, and buyers need the right capital stack.

When you represent the buyer, bring a lender who prices on cap rate and DSCR, not their W-2. That’s how you keep the commission on the deal residential agents usually hand off.

OM basics that keep MF deals alive

Six-plus unit listings without T-12 and rent roll attract lowball cash offers only. Minimum OM: unit mix, in-place rents, expenses, capex notes, and environmental flag if any. One hour of OM prep widens buyer pool to DSCR and commercial buyers — the ones who pay closer to ask.

Rent roll in the offer package

Multifamily buyer offers should include T-12 summary — sellers compare fundability, not just price. One page of NOI beats a pre-approval letter from the wrong lender type.

Rent roll in every MF offer package

Six-plus unit offers should include a one-page T-12 summary with the LOI. Sellers compare fundability, not just price — the agent who packages NOI looks like the professional in the room.

Mixed-use foot traffic

Mixed-use with retail downstairs: highlight tenant sales or foot traffic in the OM — underwriters weight commercial income differently from residential units above.

First-time MF buyer — set timeline expectations

Five-plus unit closings often run 45–60 days, not 30. Educate seller clients on longer escrow when your buyer uses commercial or DSCR financing — fewer re-trades when the calendar is honest upfront.

Parting note for your practice

Multifamily buyer reps win when the rent roll arrives with the offer — fundability beats price when sellers compare three similar numbers.

Your move: keep the deal alive

Your job isn’t to underwrite the loan — it’s to keep the client and close the transaction as they outgrow residential. When a deal crosses the fourplex line, the move is connecting your client to a lender who does commercial and can tell them fast whether it works. The cleanest path is to send the scenario over — the property and the rent roll — for a same-day read.

On compliance: recommending a lender is routine, and commercial and 5+ unit multifamily loans are business-purpose commercial loans, a different category than consumer mortgages. Keep it about serving the client, and confirm anything involving compensation with your broker and compliance. For a standing partner on the commercial and investor deals your clients grow into, our referral-partner program and broker relationship are built for it.

The bottom line

Commercial and multifamily financing isn’t a loan you have to learn to originate — it’s a boundary you learn to recognize so you keep your best clients instead of losing them at the fourplex line. Five units. Mixed-use. Any income property bigger than a fourplex. The instant a deal crosses that line, it needs commercial financing — and the agents who keep their scaling investors are simply the ones who know how to hand off cleanly instead of handing the client away.

Your client is going to buy that 12-unit building. The only question is whether you’re still his agent when he buys the next three. Send the scenario over and find out today.
