The three rules that decide if your offer is legal
Dodd-Frank/SAFE, owner-occupied status, and outreach consent — answer 'may I' before you get anywhere near 'how much.'
Most seller-financing education skips straight to the math — rate, term, present value — and treats legality as a footnote, if it appears at all. That's backwards. Whether a given structure is even permitted depends on who's occupying the property, how many properties the seller has financed recently, and how you got their phone number in the first place. Get any of those three wrong and the best-priced note in the world is a liability, not an asset.
Rule one: Dodd-Frank and the SAFE Act
Compliance — When it bites
The Dodd-Frank Act and the SAFE Act regulate who can act as a residential mortgage loan originator, and seller financing on an owner-occupied home can trigger those rules. A seller who finances more than three properties to owner-occupant buyers within a 12-month period generally needs a licensed loan originator (an RMLO) involved, along with ability-to-repay analysis and specific disclosures. A one-off sale by an individual seller, to a buyer who will live in the home, often falls under a narrower exemption — but 'often' is not 'always,' and the rules vary by state on top of the federal floor. This is not legal advice; confirm your specific structure with an attorney who handles seller financing in your state before you close, not after.
Notice the shape of the rule: it isn't about the interest rate or the down payment, it's about occupancy and volume. A landlord selling a rental to another investor faces a different — usually lighter — regulatory picture than an individual selling their own home to a family who's going to live in it. Ask which category your deal falls into before you build the note.
Rule two: outreach consent (TCPA)
Compliance — When it bites
The Telephone Consumer Protection Act governs unsolicited calls and texts, and it carries statutory penalties per violation — not per campaign, per message. Texting a list of foreclosure leads without prior express consent, calling numbers on the National Do Not Call Registry, or contacting people outside the federally permitted calling window can each expose you to liability regardless of how good the underlying offer would have been. Skip-trace data does not come with a license to text at volume — check consent status and quiet-hours rules before you send anything, and keep a record of how consent was obtained.
Rule three: due-on-sale, when the existing loan stays in place
If your structure leaves the seller's existing mortgage in place — a wrap, an all-inclusive trust deed, or a subject-to purchase — you're operating in the shadow of a due-on-sale clause the whole time. That's a real and separate topic covered in full in Module 2's third lesson, not a detail to wave off here. The short version: it's a right the lender holds, not an automatic default, but treating it as a non-issue is exactly the mistake that gets buyers and sellers both hurt.
None of these three rules are reasons to avoid seller financing — they're the conditions under which it's done responsibly. A deal that's legal, disclosed, and consented-to is a durable asset for everyone involved; a deal that skips these questions is a liability wearing a good interest rate.
