For about five properties, pay first for a repeated job you can measure, usually bookkeeping or maintenance handling. DealCheck Starter allows up to 15 saved properties for free; Stessa Essentials is free with unlimited properties. Upgrade only when a specific limit or feature blocks your routine. Keep tenant replies and document decisions under human review.
A portfolio of five units has several different jobs. Deal screening concerns future purchases; bookkeeping records the existing assets; tenant communication concerns current obligations; document reading helps find clauses and dates. One subscription rarely improves all four equally. Separate a calculation tool from a conversational AI assistant, and separate both from a property management system. The useful question is which recurring bottleneck consumes time or creates errors today.
Start with four jobs and one owner for each
Make a simple inventory before signing up. For each property, list current rent, payment route, finance and service costs, maintenance contact, lease renewal date, and where the signed documents live. Then count one month's events: candidate deals considered, transactions coded, receipts filed, tenant messages, repairs and documents searched. The counts show where software can help. An investor who looked at three deals but processed 70 receipts has a different purchasing case from one who considered 40 deals and outsourced the bookkeeping.
Choose one system of record for each fact. Rent paid should come from the bank and ledger, not a chatbot memory. A signed lease should remain the authority for its own terms. A deal-screening estimate should carry its source and date. Make a lightweight dashboard with five properties as rows and jobs as columns. Mark the person who confirms each field. If an assistant says a lease ends in August but the signed document says September, the document wins and the extracted note is corrected.
A worked illustration: five rental properties each bring in $1,500 monthly at full occupancy, or $7,500 gross scheduled rent. One property is vacant for a month, so cash rent is $6,000. Suppose recorded operating expenses total $2,100 and finance payments total $2,400. The month leaves $1,500 before any other items, reserves or tax treatment. A dashboard that uses scheduled rent would show $3,000 and mislead the owner. The stack must distinguish scheduled rent, rent actually received and costs; no AI summary can fix an incorrect source column.
For this owner, assume there are 30 transactions, 18 receipts, six routine tenant messages, one repair and eight prospective deals in a month. That workload justifies testing free deal analysis and a bookkeeping ledger first. It does not justify four separate AI subscriptions. At the next review, the owner can compare time spent on each job and decide whether a paid receipt or operations feature changes the result. All counts in this worked example are illustrative.

Buy nowDeal screening: keep the assumptions visible
DealCheck's pricing page lists Starter at $0 with up to 15 saved properties, Plus at $10 per month and Pro at $20 per month on the displayed monthly pricing view. Plus raises the limit to 50 saved properties and Pro removes it, and both paid plans start with a 14-day free trial. Those are current advertised figures, and the page also offers yearly billing, so confirm checkout terms before purchase. For an investor with eight candidate deals this month, Starter's saved-property allowance may be enough. A paid tier becomes relevant if the owner regularly needs more saved candidates, extra comparisons or another paid feature, not merely because a “Pro” label sounds safer.
Enter price, expected rent, vacancy allowance, recurring costs, repairs and financing assumptions. Keep a second column for the source of each figure: current listing, inspected bill, lender quote, comparable letting or your own estimate. If an input is a guess, mark it. Compare the tool's yield and cash-flow result with an independent spreadsheet before using it in an offer. DealCheck has investment-potential insights, but a screening score cannot inspect a roof, verify a lease or predict a future tenant. The deal-screening walkthrough goes deeper into the purchase decision.
An illustrative candidate costs $240,000, with expected annual rent of $18,000 and operating expenses of $5,400 before finance. Gross yield is $18,000 divided by $240,000, or 7.5%; the simple net operating figure is $12,600, or 5.25% of price. If an inspection suggests $9,000 of immediate repairs, a comparison that ignores that cost flatters the deal. The model may compute the arithmetic correctly while the assumptions are incomplete. Record the repair quote and rerun the scenario with it.
A second candidate example shows why an AI-written summary needs a source check. A listing describes “potential rent $1,700 monthly”; the current tenancy is at $1,400. An assistant might write “annual rent $20,400” by multiplying the potential figure. For the current cash case the annualised figure is $16,800 before vacancy. Put both scenarios in the screen, label which is contracted and which is aspirational, and do not compare one candidate's current rent with another's hoped-for rent.
Books and receipts: pay for accuracy before automation
Stessa's plan page lists Essentials as free with unlimited properties, automatic bank feeds, basic reports, document storage and up to five smart receipt scans a month. Manage is $12 monthly when paid annually or $15 on monthly billing; Pro is $28 monthly when paid annually or $35 monthly. Paid features differ, and some transactions or services may have separate charges, so use the plan comparison for the exact task. For five properties, the property count itself is not a reason to upgrade.
Begin with an account structure that separates each property and common portfolio expenses. Import one closed month. Check bank feed totals against the statements, code a sample of rent and repair items, and keep receipts attached to the actual transactions. Do not let an AI categoriser decide tax treatment unreviewed. A plumber's $650 invoice might include a routine repair and an upgrade; the invoice wording and the accountant's judgement matter. The owner should ask a qualified adviser about the proper treatment rather than let a label make the decision.
Suppose the illustrated portfolio has 18 receipts each month. Five free scans leave 13 to file by another route. If the paid feature would save two minutes of accurate entry per extra receipt, the rough time released is 26 minutes monthly. At $28 monthly for Pro on annual billing, the owner should ask whether other Pro features also solve a real need. If manual review still takes one minute per receipt, the net time saving is smaller. Test ten receipts with varied layouts before assuming scanning works on this set.
A faded $86 hardware receipt is a useful trial. A sample extraction might return $68 and place the purchase under “utilities”. The correct action is to inspect the image, change the amount and category, and keep the image with the record. Another receipt covers parts for two properties. Even perfect total extraction will not split it correctly without instructions. Decide whether splitting is worth the extra work, and record an allocation note. This is why “AI receipt scanning” should be assessed by reconciled entries, not scans completed.
Tenant messages: use a small approved library first
With five properties, tenant communication may be episodic. A short approved message library can answer routine questions without a paid chatbot. Keep a property-specific sheet with the repair reporting channel, access procedure, payment contact and emergency instructions. The assistant can help draft a courteous reply, but it should not promise an appointment, interpret a lease dispute, disclose another tenant's details or diagnose a safety issue. The owner or manager checks the message before sending. Before buying anything for this job, look at what the bookkeeping tool already includes: Stessa's free Essentials tier lists maintenance requests, maintenance tracking and online rent collection, which may cover the intake side of tenant contact without a separate bot. The landlord message assistant tutorial covers an automated channel if volume later warrants it.
A sample incoming message says, “The boiler stopped this morning. Can I get someone today?” An illustrative AI draft might say, “A technician will be there by 4pm.” That promise is unsupported. A checked reply is: “Thanks for reporting this. Please use the emergency contact in your tenancy information if there is an immediate safety concern. I am checking availability and will confirm an appointment once the contractor responds.” Add the property ID and preferred contact channel to the internal work order, but do not put sensitive notes into an unrestricted prompt.
Another concrete case: a tenant asks whether a pet is allowed. The signed agreement, any later variation and applicable rules govern the answer. A generic assistant may confidently say “pets are welcome” based on a website FAQ from a different property. Ask it to locate relevant clauses in the correct document, then verify the text and respond personally. For disputed, formal or legal notices, seek qualified advice. A chatbot should never generate and send such a notice without a human check.
Decide on a paid chatbot only after recording message volume, response times and repeated questions for several weeks. A simple threshold is a management rule, not a market fact: if the owner handles fewer than ten routine questions weekly and most need property-specific judgement, keep templates. If many repetitive questions arrive outside working hours and the knowledge base is reliable, test a bot with a clear human handover. Measure wrong answers as well as speed. A fast wrong repair promise can create more work than a slower accurate reply.
Document reading: use AI to find, then verify
Five properties can still produce leases, inspection reports, insurance schedules, finance documents, contractor quotes and correspondence. An approved AI assistant can help extract dates, summarise a long report or compare a quote to a scope. It should not become the document archive. Keep the original in a controlled repository with a property ID, document type, effective date and version. Before uploading anything, check the assistant's data settings and your obligations to the people named in the file. Redact unnecessary identifiers; obtain appropriate permission when confidential data is involved.
A useful prompt template is: “Using only this document, list the renewal date, notice procedure, repair responsibilities and clauses that support each answer. Write ‘not found’ where the document does not say. Do not infer legal effect.” An illustrative output might list “renewal date: 30 June; clause 8”. The owner then opens clause 8 and discovers it says the rent-review date, while renewal is in clause 12. Correct the record and test whether the tool consistently cites the wrong heading. The prompt is a search aid, not a legal interpretation.
For a contractor comparison, give the assistant two redacted quotes and ask for a table of scope, exclusions, proposed start, warranty wording and total. A sample output may show Quote A at $2,400 and Quote B at $2,150. If Quote B excludes disposal worth an estimated $400, the apparent cheaper option may cost more. Check the quoted text, ask the contractors to clarify missing items and make the choice on comparable scope. The lease and application checks tutorial handles risks that a generic document summary cannot resolve.
Do not purchase a dedicated document AI product simply to run a few lease queries a year. A general assistant usually covers this job. ChatGPT and Claude both have free tiers; on their pricing pages ChatGPT Plus is $20 a month (a lighter Go plan is $8), and Claude Pro is $20 monthly or $17 a month billed annually. Try the assistant already authorised for the business, with synthetic or redacted documents first, and read its data settings before any signed lease goes in. Record how often it finds the correct clause, how long verification takes and how often it invents an answer. If the work is occasional, a manual index and good filenames may be cheaper. If the portfolio has frequent acquisitions or complex documents, compare paid document tools on the actual file set and ask a qualified adviser to review legal conclusions.
Set a spending gate for each upgrade
Use a four-column purchase note: repeated job, baseline minutes and errors, feature being bought, and result after a trial. For DealCheck Plus, the trigger might be more than 15 live candidate records or a needed comparison feature. For Stessa Manage, it might be a specific operations task that Essentials cannot handle. For Pro, test advanced transaction tracking or receipt scanning against the monthly books. For an AI assistant, the gate is an approved data route and a repeatable document or drafting task. Do not combine unrelated features into one claimed saving.
Consider three illustrative monthly budgets for the five-property owner. A lean trial with DealCheck Starter and Stessa Essentials has $0 in those software subscriptions, plus the owner's time and any separate transaction or service charges. Adding Stessa Manage on annual billing makes that line $12 monthly. Adding DealCheck Plus as well makes the two displayed plan prices total $22 monthly. If the owner chooses Stessa Pro instead of Manage, the paired list prices total $38 monthly (DealCheck Plus at its monthly price, Stessa Pro on annual billing). If the owner also pays for one general assistant seat at $20 monthly for document questions and reply drafts, the fullest version of this stack reaches $58 a month. These sums exclude other services and are not claims about total portfolio cost.
Run a one-month ledger and one deal through the proposed stack before migrating history. If bank balances fail to match, fix imports and categories first. If deal outputs disagree, compare assumptions and formulas. If tenant replies require frequent edits, improve the source information or return to human drafting. If document summaries cannot cite the right clause, stop relying on them. Each failure identifies a data or process problem that a higher subscription tier may not solve.
At the quarterly review, delete unused trials, export the data you need and record who can access each account. Check whether the tool now stores lease copies, tenant details or bank data; that affects permission and retention decisions. Keep the owner able to complete a rent chase, maintenance response or deal comparison without an AI service. The compact stack wins when it makes figures easier to verify and messages easier to handle, not when it displays the largest number of AI features.
Check the handoffs between the four jobs
A portfolio stack fails at the handoffs as often as inside a tool. An accepted deal estimate should not automatically become a booked asset value. A tenant's repair message should become a tracked work order, then a contractor invoice, then a categorised transaction, but each step needs a human confirmation. Give every property a stable code used in folders, expense records and maintenance notes. If one system calls it “Unit 3” and another “Flat C”, document the mapping. Otherwise a smart search can confidently attach the correct invoice to the wrong property.
In a sample repair chain, property P-04 reports a leaking tap on Monday, a contractor quotes $190 on Tuesday and completes the work on Thursday for $215 after replacing an extra part. The owner records the original request, approved variation, completion evidence, invoice and payment in one trail. An assistant may summarise “repair cost $190” from the quote unless it sees the final invoice. The ledger should use $215 when the bill is accepted and paid; the quoted amount remains useful as a variance explanation. This example shows why a summary should carry source type and date.
Try a deliberate mismatch in the pilot. Upload a contractor invoice with P-04 in the filename but P-05 in the body. The correct outcome is an exception for owner review, not an automatic posting. Then test a lease with an old renewal date and a newer signed variation. The assistant should show both sources and leave the effective date unresolved until the owner checks the documents. These are small tests, but they reveal whether the stack supports evidence or merely repeats the first plausible text it encounters.
Plan for leaving a tool as well as joining it. Export a month's transactions and attachments, open them in an ordinary file viewer, and see whether property codes and dates remain understandable. Save the original lease and repair records independently of any generated summary. If a paid tier is cancelled, the owner should still know which rent is due, which contractor is booked and which documents govern an obligation. A clean exit test is part of deciding whether the subscription is worth keeping.
Questions before adding a portfolio subscription
Should five properties have a paid AI chatbot for tenants?
Usually start with a clear repair intake form, emergency instructions and reviewed message templates. Count the monthly enquiries that still require repetitive replies. A paid bot needs an accurate property-specific knowledge base, privacy controls and a human handover route. If only a few messages arrive weekly, a separate chatbot may add more oversight work than it removes.
Can AI choose the next property to buy?
Use a tool to organise assumptions and calculate scenarios, then verify rent, costs, finance terms and condition yourself. A model's yield or investment-potential label is only as reliable as the entered figures. Compare the output with an independent spreadsheet and speak to qualified property, finance and tax advisers before making a binding commitment.
When does a paid receipt feature make sense?
Measure the number of receipts and the time spent entering them accurately each month. A feature is valuable when it reduces repeated keying without creating more correction work. Test ten varied receipts, including faded images and split expenses, and compare the monthly cost with verified minutes saved. Keep the original evidence and review account coding.
