Keep the evidence.
Find the open questions.
A working notebook for one property. Record what you have, what is still an estimate, and the next question to resolve.
Your assessment, not StackX verification. “Documented” means you have supporting material to review. It does not establish accuracy, suitability, permitted use, or that a property is ready to buy.

These are counts of your labels, not an investment score. Open any item to add evidence and a next action.
Rent & income
Separate documented collections from an assumption about future rent.
Leases and rent actually collectedMissing
Gather leases, a current rent roll, payment history, deposits, concessions, and utility responsibilities. Record the difference between scheduled and collected rent.
A link and a “Documented” label do not validate the source. Review the material and its applicability.
Current rental comparablesMissing
Compare location, size, condition, terms, concessions, and evidence date. An advertised rent is not proof of a signed lease; city medians are not property rent estimates.
A link and a “Documented” label do not validate the source. Review the material and its applicability.
Expenses & reserves
Identify the ongoing bills and the larger costs that arrive less often.
Property taxes and assessmentsMissing
Inspect the property record and current bill. Ask the local taxing authority what could change after purchase or planned work; keep any assumptions visible.
A link and a “Documented” label do not validate the source. Review the material and its applicability.
Insurance for the intended useMissing
Obtain a property-specific quote. Record premiums, deductibles, exclusions, coverage period, and any unanswered questions about the proposed rental use.
A link and a “Documented” label do not validate the source. Review the material and its applicability.
Operating costs and replacement reservesMissing
Gather utilities, management, association fees, maintenance history, and other recurring costs. Separate major replacements from routine repairs and avoid counting a cost twice.
A link and a “Documented” label do not validate the source. Review the material and its applicability.
Financing & cash
Understand the full cash commitment and the actual borrowing terms.
Loan terms and future payment changesMissing
Record principal, interest, fees, amortization, maturity, rate adjustments, guarantees, and any balloon payment. Keep a proposed refinance separate from confirmed financing.
A link and a “Documented” label do not validate the source. Review the material and its applicability.
Cash needed before rent beginsMissing
List the down payment, closing costs, immediate work, financing fees, holding costs, and cash kept in reserve. Note when each payment is due.
A link and a “Documented” label do not validate the source. Review the material and its applicability.
Condition & repairs
Connect the physical findings to a budget and a realistic schedule.
Inspection and major building systemsMissing
Arrange an appropriate inspection. Record findings about the roof, structure, mechanical systems, plumbing, electrical systems, and any specialist follow-up recommended.
A link and a “Documented” label do not validate the source. Review the material and its applicability.
Repair scope, quotes, and timingMissing
Connect the inspection findings to written scopes and estimates. Identify permit questions, contingencies, lead times, and any period when the property cannot earn rent.
A link and a “Documented” label do not validate the source. Review the material and its applicability.
Local records & intended use
Take property-specific questions to the relevant records and professionals.
Intended use and unit configurationMissing
Ask the relevant local authority about the intended rental use, unit count, occupancy, and required approvals. A listing description does not establish what is permitted.
A link and a “Documented” label do not validate the source. Review the material and its applicability.
Title, access, and association recordsMissing
Review available title, easement, access, and association information with the appropriate professional. Record restrictions, charges, open questions, and missing documents.
A link and a “Documented” label do not validate the source. Review the material and its applicability.
Hazards, utilities, and site recordsMissing
Consult property-specific flood and local site records, utility information, and relevant professionals. A regional hazard layer or an absence of mapped risk does not establish site suitability.
