Built for how you invest

Long-term leases, short-term stays, or a stack of statements you dread every April — pick your world and watch it work.

Long-term rentals

See who’s paid — and who’s behind — at a glance

Every unit shows expected vs received and the net to you after management fees. One tap on “Past due” rolls up everyone behind, added across every overdue month.

Stop typing. Know where you stand. Make better decisions.

Independent investors spend most of their time entering data — and very little actually managing the asset. Keystone IQ flips that ratio. Here's how, on day one.

AI bookkeeping

The AI reads the document and writes the ledger.

Drop in a mortgage statement, an owner packet, or a stack of invoices. Keystone IQ extracts every line, splits principal from interest, and books it to the right property.

PDF & HTML statements, owner packets, invoices
Duplicate-safe — the same statement never posts twice
Every row keeps a link back to the source document

Vendor spend

See exactly where every dollar goes.

Every payment is grouped by vendor and by category automatically — no tagging, no spreadsheets. Spot your biggest costs, catch a vendor you've grown over-reliant on, and see how spend splits across capital, operating, and fees at a glance.

Ranked by vendor and by category, portfolio-wide
Top-vendor concentration surfaced automatically

Occupancy & leases

See who's leased through when — the whole year at a glance.

A live occupancy timeline across every unit: current leases, renewals pending, and exactly when each one expires — so a vacancy never sneaks up on you. Every property groups its units with rent and occupancy right alongside.

Every unit's lease term on one timeline
Renewals and expirations flagged before they bite
Portfolio occupancy and vacancy, year-to-date

Your portfolio gets a grade —
and tells you why.

Every property gets a 0–100 Health Score across five weighted factors — including its Operating Expense Ratio (OER) and Debt Service Coverage Ratio (DSCR). When the score moves, AI surfaces which factor changed and walks through the numbers behind it — the one read no spreadsheet gives you.

See exactly how the score is calculated

Why you can act on these

Computed, not generatedThese come from arithmetic on your ledger, not from a model’s guess. The same portfolio always produces the same list.

Only your own dataYour transactions, leases and policy dates — nothing inferred from other people’s portfolios or from the open web.

Every formula is publishedNOI, DSCR, OER, cap rate, equity and the Health Score weights are written out in full, so you can check any number yourself.

Read the methodology

Market-rent comparisons use an automated estimate, not an appraisal.³ Keystone IQ surfaces the opportunity and the arithmetic behind it — the decision stays yours.
