Pick one asset class and one geography
Off-market sourcing fails most often because the outreach tries to cover too much ground. An owner of a 40-unit multifamily building and an owner of a self-storage facility have almost nothing in common as buyers of your pitch, even if both fit inside a broad real estate investor thesis.
Choose a single asset class, multifamily, industrial, retail strip, or self-storage, and a geography small enough that you could plausibly know the submarket by name. Add a size band too, doors or square footage, that matches your actual buy box. This becomes the description you give AI Leads, and it's also the description that makes your email sound like it came from someone who actually buys this type of property, not a form letter.
Write your actual buy box criteria down alongside the asset class, unit count range, year built, or condition if that matters to your investment thesis. When you narrow that far, the list AI Leads returns is small enough that you can review every contact before launch, which matters more for off-market sourcing than for almost any other cold email use case.
Source owners, not just properties
Describe the target to AI Leads as owners of the asset class and geography you picked. Because many owners hold property through an LLC, the enrichment step matters here, you want the actual person behind the entity, not a generic company inbox. Import a CSV of owners pulled from county records or an LLC-ownership database if you already maintain one, that data source is often more precise than a generated list for this use case.
The quality funnel filters weak matches before they cost credits, which matters more here than in most industries, because a bad match in off-market sourcing wastes a contact and can also read as an unsolicited, slightly unsettling email to someone who owns the property personally.

Bring property specifics into the CSV, then let research add the rest
Source the property specifics yourself, when it was acquired, how long it's been held, any recent permits or nearby listings, from county records or a listing data source, the same place you likely already pull the owner list from in step 2. Add those details as custom fields on each contact before you import, since FirstSales doesn't pull property history or photos on its own, it works from what you bring in.
Contact research still runs automatically before drafting, and the transparency view shows exactly what it found and used in the draft, mostly company and role context that rounds out who you're emailing. In Teach or your campaign instructions, tell the AI to draw on the hold length and other specifics you added, so the draft references something real about the property instead of only what research surfaces about the owner.
Owners who've held a property for 10+ years respond differently than someone who bought two years ago. A long hold often signals openness to a conversation about liquidity, a recent purchase usually doesn't. If county or listing data consistently comes back thin for this asset class, that's a sign to swap in a better source rather than let the AI write around missing information.
Deferred maintenance is another signal worth sourcing. A property that shows visible wear in photos you've reviewed, or an owner who hasn't refinanced in years despite favorable rate windows, often points to an owner who is tired of active management. That's a very different opener than one built around a recent renovation, where the owner has likely just reinvested and is unlikely to consider selling soon.
Set the offer as a conversation, not a purchase
In campaign guidance's describe step, frame the goal honestly: a no-pressure conversation about whether they'd consider selling, not an offer or valuation. Owners who get an unsolicited number in a cold email are far more likely to ignore it than owners who get asked an open question.
In the teach step, write your positioning as a buyer who closes without financing contingencies, without a broker's commission eating into their number, or without the property going on the open market, whichever is actually true for you. Be specific about what makes you different from a listing process, that's the entire reason an owner would consider an off-market conversation at all.
Run a few sample drafts through the practice step and read them as an owner would, someone who wasn't planning to sell today and got an email out of nowhere. If the draft pushes for a number or a meeting in the first line, rewrite the describe step to slow it down. The best-performing off-market openers read like an introduction, not a solicitation.

Write in your own voice, and keep it short
Paste past outreach emails into the teach-writing-style step if you have them. If this is your first cold outreach effort, write two or three samples yourself in the tone you'd use calling someone directly, plain, respectful, no pressure.
Subject: your property on [street name]
Hi [First name],
I buy [asset class] in [submarket] and noticed you've owned the building on [street] for a while. Not sure if selling is even on your radar, but if it ever is, I'd rather have a direct conversation than have it go through a broker process.
No pressure either way, just wanted to introduce myself in case the timing is ever right.
[Name]Notice there's no price mentioned and no urgency language. Off-market outreach earns trust slowly, the email's job is to open a door, not close a deal.
Sign the email with your real name and a direct way to reach you, phone number included if you're comfortable sharing it. Owners considering an off-market conversation are more likely to pick up the phone than reply to an email thread, and giving them that option removes one more piece of friction between curiosity and a real conversation.
Build a light, patient sequence
Set up two to three follow-up steps with longer delays than you'd use in a typical B2B sequence, two to three weeks apart rather than days. Steps stop automatically on reply. Off-market owners are not evaluating you against competing vendors on a deadline, they're deciding whether to even think about selling, and that decision takes time.
Keep each follow-up short and low-pressure. A second touch might simply mention a recent comparable sale nearby, a third might just re-open the door months later. Resist the instinct to add urgency, it works against you in this category.
It also helps to rotate the angle across the sequence rather than repeating the same ask three times. The opener introduces you, the second touch offers a piece of market information the owner didn't have, and the third simply keeps the door open without asking for anything. An owner who wasn't ready to reply to the first email may still read the second and third, and each one builds a little more familiarity even without a response.

Handle replies personally when they matter most
Replies land in the unified inbox and AI reply handling answers based on what the owner actually asked. Bounce handling auto-suppresses bad addresses so the list stays clean over what is often a long sourcing campaign.
Off-market replies are lower volume but higher stakes than most cold email categories, a single interested owner can be worth the entire campaign. Review these threads yourself rather than leaving them fully on autopilot, at least until you've calibrated how the AI handles specific ownership and timeline questions.
Some replies won't be a yes or a no, an owner might say they're not selling now but ask you to check back in a year. Treat that as a real outcome worth tracking outside the campaign, not a dead end, since off-market sourcing is as much about staying top of mind over years as it is about any single campaign's numbers.

Expect a slower, wider reply band and adjust accordingly
Off-market owner outreach is an under-fished niche compared to standard B2B, so reply rates often land higher, in the 3 to 8% range, with meetings in the 1 to 2.5% range. That's a range, not a guarantee, and it depends heavily on how tightly your list matches real owners of the exact asset class and geography.
Check per-step performance in analytics. If the opener gets replies but they're mostly not interested, that's a targeting problem, not a copy problem, tighten the geography or asset class further. If replies are rare but warm when they happen, the list is right and it's simply a patience game.
Track results over months rather than weeks for this playbook. An owner who ignores the first sequence entirely might reply to a re-engagement email six months later when a personal circumstance changes. Off-market sourcing rewards a durable, low-pressure presence in a market far more than a single well-timed burst of outreach.

Profi-Tipps
Weight toward long-hold owners
Owners who've held a property through a full market cycle (10+ years) are consistently more receptive than recent buyers, weight your list toward hold length if the data is available.
Never mention a price in email one
Never mention a price or valuation number in the first email. It turns a conversation opener into a negotiation the owner didn't ask for.
Look up the registered agent yourself
If an LLC name doesn't resolve to a real person through enrichment, it's often faster to look up the registered agent yourself than to keep running that lead through automated research.
