Subject-matter triage (only if applicable) - Treat the letter of intent as the economic baseline, then test every later note, diligence finding, and operating exhibit against it before drafting. - Identify whether the source set contains one deal path or multiple contingencies; if there is more than one open path, separate them before drafting operative language. - Draft the agreement first and the issues memo second; do not let the memo substitute for a completed contract. - Preserve deal-specific assumptions only if they are supported by the source materials; otherwise bracket them for confirmation. ## 2. Failure modes the skill is correcting - Drafting from the letter of intent alone and missing later negotiation points, which leaves the agreement out of sync with the actual transaction. - Failing to translate diligence findings into representations, disclosure schedules, covenants, or indemnity provisions, which leaves known property risks unallocated. - Omitting rent roll and operating data in the lease and income representations, which creates internal inconsistencies and closing disputes. - Using generic real-estate forms without conforming the mechanics for deposit, diligence, closing deliverables, prorations, survival, and remedies to the deal record. - Leaving title, survey, environmental, or inspection issues unstated in the draft, which forces late-stage rewrites. - Producing only an issues memo or only a draft PSA, rather than both deliverables. ## 3. Legal frameworks / domain conventions that apply - Use the customary commercial PSA structure: purchase price, earnest money, diligence period, title and survey review, conditions to closing, representations and warranties, covenants, closing deliverables, prorations, casualty and condemnation, default remedies, survival, and miscellaneous provisions. - Conform the draft to the letter of intent on price, deposit timing, diligence rights, closing date mechanics, and any expressly agreed seller or buyer obligations. - Use title commitment, survey, and legal description materials to define permitted exceptions, objection rights, and the deed description. - Align lease and income representations with the rent roll and operating statements; if the source materials diverge, disclose the variance and choose a closing condition or a bringdown covenant. - Treat environmental and inspection findings as drafting inputs to knowledge qualifiers, special disclosures, remedial covenants, indemnities, or purchase price adjustments, depending on how the source record allocates risk. - Include ordinary-course operating covenants that restrict material lease changes, new contracts, casualty actions, and other pre-closing conduct inconsistent with the agreed baseline. - Include prorations and adjustments for taxes, rents, security deposits, reimbursements, utilities, and similar recurring items using a clear closing statement mechanism. - Address non-foreign seller certification and related withholding mechanics under FIRPTA, 26 U.S.C. § 1445, if the source materials indicate a taxable real-property transfer. - Address post-closing survival and liability limitation terms explicitly, because those terms govern the practical value of the representations and indemnities. - Use controlling legal authority for any affirmative legal proposition stated in the drafting or memo; do not state a conclusion without naming the governing rule, statute, regulation, or standard practice. ## 4. Analytical scaffolds - Extract every economic and timing term from the baseline deal record, then test later notes for additions, deletions, or overrides. - Walk the source set document by document, and for each point ask: is this already reflected, does it need a new clause, does it belong in an exhibit, or does it remain open? - For each diligence issue, determine the correct drafting home: representation, schedule, covenant, condition precedent, indemnity, or casualty-style adjustment. - For each lease or operating data point, confirm the parties, term, rent, deposits, options, defaults, and income treatment are internally consistent before writing the representation language. - For each title or survey item, decide whether it is a permitted exception, an objectionable item, or a closing deliverable to be cured. - For each open point, either resolve it in the draft if the source materials supply the answer, or leave a bracketed placeholder only where the record truly does not support a final term. - For the companion memo, frame each issue as: source, conflict or gap, drafting choice, legal or transactional consequence, and any item still needing direction. - Where the transaction turns on a specific doctrine or statutory rule, cite the authority directly in the draft note or memo discussion rather than relying on generic phrasing. ## 5. Vertical / structural / temporal relationships (only if applicable) - Make sure the deposit and diligence timing work together so the buyer’s risk increases only as intended by the source materials. - Make sure any extended diligence tied to environmental review or inspection findings is long enough to support the stated investigative rights. - Make sure rent roll dates, operating statement periods, and lease representation dates all align with the closing snapshot used in the agreement. - Make sure covenants during the interim period preserve the condition of the property and the economics that the PSA assumes at closing. - Make sure closing deliverables, including deed, assignment documents, bills of sale, FIRPTA materials, and estoppel-style items if requested by the source record, are cross-referenced consistently. ## 6. Output structure conventions - Purchase and sale agreement: draft as a complete, stand-alone commercial PSA with conventional article sequencing and transaction-specific exhibits or schedules. - Use clear exhibit references for the legal description, title objections or permitted exceptions, rent roll, form conveyance documents, and any disclosure schedules. - If a source item is unresolved, bracket it in the agreement and flag it in the memo; do not silently omit it. - Drafting issues memo: organize by source document or issue category, using a concise issue / resolution / remaining question format. - For each memo entry, state the issue, explain how the draft addresses it, and identify any remaining approval item or factual gap. - End the memo with a short Recommended Actions section that assigns the next step to the appropriate role and ties it to the transaction milestone. - Before finishing, confirm that the PSA file is complete and operative, and that the issues memo actually records the drafting decisions rather than merely describing the source materials.
