How to Buy a Net Lease Property, Step by Step

The process, as we actually run it on the buy side — each step now carrying the substance that used to live in separate diligence, risk, and cash-flow notes. The whole thing is available done-for-you through free representation.
Step 1: criteria before search
Price band and equity, financing posture (cash, 60–65% leverage, 1031 constraints), yield floor, risk appetite (corporate versus franchisee credit, term length), geography, and management tolerance (absolute-net only, or NN with reserves priced?). One page, written down. Every later decision checks against it — and unwritten criteria drift with the last shiny flyer.
First commercial purchase? The vocabulary change is larger than the economics change. Multifamily is operations-heavy and financing-friendly. Industrial is institutional and thin at quality. Office is a specialist’s demand question. Retail splits into failing formats and thriving ones; single-tenant net lease is the thriving end’s passive expression. Acquisition loans are underwritten as businesses: leverage usually sits in the sixties to mid-seventies, with long amortizations that still balloon and a look-through of your global cash flow. There is no thirty-year residential fixed. Value equals NOI ÷ cap rate — retrain house-comp instinct onto leases.
Step 2: source wider than the portals
Portals show most of the market late. Add: broker networks circulating deals pre-listing, developer pipelines pre-selling new construction, and direct criteria registration with buy-side shops (that’s us). The goal isn’t secret inventory mystique — it’s seeing the same deals earlier and a meaningful slice others never see. Browse live inventory for what is on the tape today; do not treat any marketplace as the whole market.
Step 3: underwrite in layers — and know what prices the cap
Screen (thirty seconds: tenant, term, cap, market — kills 80%). Financial (the real yield: verified rent, honest expenses on NN paper, escalation schedule, re-lease math against corridor comps). Lease (the maintenance article, options, assignment, termination rights). Tenant (corporate ratings or franchisee unit counts and coverage). Market (trade-area anchors, competition map, the state page fundamentals). Deals die honorably at every layer; that’s the system working.
A cap rate compresses three questions: location quality, document quality, and remaining firm term. State and metro set the base spread — Florida can price identical paper 50–100 bps inside Ohio — and the corner sets residual value when the lease someday is not there. Structure, bumps, guarantee, kick-outs, and ROFRs are the lease axis; two identical caps with different maintenance articles are not the same price. Years to firm-term end drive financing and the renewal bet. Bargains cluster where the axes disagree (great dirt, mediocre paper; great paper, unloved state). Trap deals cluster where all three agree they are perfect — that consensus is a 4.5% cap.
Step 4: offer with structure
LOI with the terms that matter: price, diligence period (21–30 days), financing contingency reality, estoppel requirements, and 1031 cooperation if applicable. Negotiate with the comps you built in step 3 — leverage in net lease comes from demonstrable alternatives, so maintain a live pipeline until contract.
Sellers of stabilized assets price certainty like yield. Proof of funds, a diligence window you will actually honor, a term sheet already in hand, and a closing date with slack each buy basis points — especially from a 1031 seller whose calendar prices delay in tax dollars. Diligence findings (saturated roof core, estoppel dispute, rent 20% over corridor, NN paper the flyer called NNN) reprice credibly because they will reprice for the next buyer too. Ask for economics, not a performative punch list. Non-price asks often beat the last $25K: seller-funded estoppel and SNDA on your lender’s forms, warranty assignments, survey and title-cure costs, cooperation both directions. Listed-broker files want comps; developer exits want the fund calendar; estate sales want certainty. Some correctly priced deals should not be negotiated.
Step 5: diligence like it’s the last chance
Because it is. Two checklists, run in parallel.
The document. Pull the original together with amendments, assignments, commencement memos, and side letters — offering books reliably skip one. Match that stack to the estoppel’s amendment list. Then read, in order of consequence: maintenance allocation component by component; term, options, kick-outs; escalations and option-period treatment; assignment and whether the guarantee survives; casualty and condemnation; use, exclusives, co-tenancy; estoppel and SNDA delivery windows; ROFR/ROFO. Three documents must agree: lease, estoppel, rent history. The gap between the flyer and the paragraph is where the price conversation actually lives.
The site. Schedule B is a reading assignment: easements through the drive-thru, reciprocal agreements tying the pad to a center you do not control, leftover exclusives. The ALTA survey overlays those promises on dirt. Phase I always; Phase II where history indicates — fuel is obvious, a dry cleaner under a later dollar store is not. Inspect roof, HVAC age, slab, and ADA even on absolute paper; on NN allocations this inspection is the bid. Zoning letters should confirm conforming use, parking, rebuild rights after casualty, and whether the drive-thru is a privilege that dies with alteration. Traffic, DOT maps, and competitor pads tell you what the box is worth when the lease asks the residual question.
Request both letters when diligence starts — waiting until the lender asks is how closings slip. National tenants negotiate SNDAs on their own forms at their own pace.
Step 6: know the risks you are buying
They are short and priceable. Binary vacancy — mitigate with a dark-box bid test, several smaller deals instead of one large, and corridor quality. Credit migration — underwrite the store (sales, role in the network) beside the parent, and read how weak an assignee can legally become. Re-lease cliff — contract rent versus realistic replacement rent; deals above ~130% need some other reason to exist. Drugstore rents often halve at re-tenanting; some single-purpose boxes barely convert. Duration — long flat paper is a bond in brick; annual bumps self-hedge. Event risk — casualty clauses, condemnation near highway corners, environmental history, zoning letters. The investors who get hurt skipped the reading, not the luck.
Cash flow after the rent check
On absolute paper, contract rent minus near-zero landlord expenses is NOI. NN subtracts reserves here — the honesty adjustment. All-cash, you pocket NOI. Levered at 65% LTV in a tight cap-to-rate spread, cash-on-cash can look worse than unlevered until principal paydown and the tax layer join the count. Leverage in this cycle is often a total-return choice, not an income multiplier.
Depreciation shelters the taxable slice; interest deducts; high earners may bank paper losses until a sale. Escalations are the compounding most flyers underprice: a 10% every-five schedule lifts a 6.5% going-in yield into the high-sevens on cost after a decade; two-percent annual steps get there sooner. Model the whole schedule in the cap rate calculator, never year one alone.
Step 7: close and operate lightly
Wire through escrow, assignment of lease, rent commencement notice to the tenant. Then the pleasant anticlimax of net lease ownership: deposit rent, file taxes, watch the option calendar — the lease expiry tool does the watching.
