We write the scope.Everyone builds on it.

Maintenance breaks on doubt, not price. Baseline writes the scope first — neutrally, from evidence, before anyone shows up — so the owner, the PM, and the vendor all trust the same number.

One shared file. One shared truth.
The problem

The owner holds the wallet and the least information.

An owner who knew the work was needed would pay the asking price. They can't verify what's broken, what it costs, or whether the quote is fair — so they doubt, delay, and the property manager absorbs the friction.

The solution

Baseline is the trust layer. Every case sharpens the next.

Not a marketplace. Not a dispatcher. The neutral layer that writes the scope — diagnosis, scope, price, evidence — so owner, PM, and vendor see the same truth at the same moment.

01

Objective diagnosis

Owner, tenant, vendor, and PM work from the same Baseline understanding of what's wrong. Confidence-scored. Multimodal. Written before the truck rolls.

Photos + historyConfidence scoreRepair library
02

A living scope

The scope updates as the root cause resolves — materials, labor, alternatives — always current, always priced against regional comparables.

Structured scopeRegional benchmarkRepair vs. replace
03

Trust, verified

Quality gates at every step. Payment is designed to release on verified completion. Reputation is built to travel across the network — so reliable vendors earn more work over time.

How it works

From problem to documented decision, in one closed chain.

One case, end to end — illustrated. We read the home's Genome and write the scope; your PM makes the call. Each handoff is structured, and each closed case writes back to the model. The mechanism is the act; the trust is the product.

How certainty compounds

Certainty compounds with every signal.

A case starts with the cheapest signal — a tenant's text and a photo — and stops the moment it's sure. The expensive signal, a vendor on-site, is added only when the cheap ones don't resolve it. The curve below is illustrative — it shows the shape, not measured rates.

The gap between what we predicted and what happened is the lesson. Compounded across every case, we reach certainty earlier — and cheaper — and the advantage widens instead of getting copied away.

How a case runs

Monday, 4:12 PM. One leak. Two outcomes.

Not an emergency — a slow leak in a duplex water heater. The kind of decision that, without Baseline, takes four days of email tag before the owner approves an $1,800 tank that turns out to be a $42 valve.

Tenant report

There's water on the closet floor by the heater. Maybe a quart. Still getting hot water but I can hear it cycling. Towel down for now?

Mon · 4:12 PM2 photos · puddle near the tank base · T&P discharge tube
Without Baseline

Four days of email tag. The owner approves $1,800 to replace a tank that wasn't failing. The real cause — a $42 valve — is never diagnosed.

  • Mon 4:12 PM

    Tenant texts the on-call line. PM opens a one-line ticket.

  • Mon 4:35 PM

    PM emails the owner: 'Water heater leaking, recommend dispatch. $300–$1,500.' No diagnosis.

  • Tue 10:00 AM

    Plumber on-site. 'Tank's done. $1,800. Soonest: Thursday.' No itemization.

  • Wed–Thu

    PM chases the plumber for clarification. No callback. Lines up a second bid.

  • Fri 2:00 PM

    Owner approves $1,800 to end the back-and-forth. Four days of leak — drywall is staining.

With Baseline

The owner approves a $208 valve-first scope in 86 minutes. The diagnosis is right, the tank stays in service, the closet is dry by lunchtime the next day.

  • Mon 4:12 PM

    Tenant submits the report + 2 photos through Baseline.

  • Mon 4:17 PM artifact

    Diagnostic: 78% T&P relief valve · 14% tank · 8% supply line.

  • Mon 4:25 PM artifact

    Two scopes drafted: $185–$220 valve, or $1,420–$1,560 tank if the on-site test fails. Benchmarked against comparable regional jobs.

  • Mon 4:42 PM artifact

    One-page decision packet to the owner — plain summary, both scenarios, comp pricing, photos.

  • Mon 5:38 PM

    Owner approves the valve-first scope. 86 minutes after the tenant's text.

  • Tue 10:18 AM

    Valve confirmed, replaced, tank pressure-tested clean, tenant confirms dry. Payment released.

Owner value

The problem is objective. The decision is yours.

We get the diagnosis right for everyone. Then we get the decision right for this owner. The same problem, in the same home, has a different right answer depending on what you're optimizing for.

Most tools collapse the problem and the solution into one recommendation. Baseline decouples them — so a property manager can serve every owner the way that owner wants to be served.

The Genome

The complete record of your home. We remember so you don't have to.

Every scope Baseline writes is a deposit into your home's genome — its configuration, materials, and behaviors. The record makes the next decision sharper, and it goes to work for you against everyone who holds information you don't.

For property managers

Know the answer before they ask.

Every owner wants something different — maximize cash flow, protect the asset, stay hands-off, be consulted on everything. Baseline gives you what you need to handle each repair on their terms: clear, benchmarked options matched to what that owner actually cares about, so when the owner asks, you already have the answer.

The seat you’re in
The modal U.S. PM

Third-party residential — a solo operator or small team on 5–15% margins. The seat every repair has to pass through.

First PM pilot under contract — Q1 2026
  • 01Every tenant report, every owner question, every vendor scope dispute routes through you.
  • 02You're the lowest-margin seat in the chain — and the one that absorbs all the friction.
  • 03When an owner asks “is this fair — do we really need it?”, you're answering from instinct, not evidence.
What changes with Baseline
Coordination, collapsed
150 hrs / month≈ one full-time coordinator's load at a ~750-door book
28 hrs / monthoversight only — Baseline runs the coordination; you make the calls that matter
What the owner receives
today

A phone call and a number — and a manager hoping they say yes.

with baseline

A documented recommendation with two or three benchmarked options, each with the reasoning and the trade-offs laid out.

You stop defending decisions and start presenting them — the owner chooses on their terms, and sees a manager who's on top of it.
Owners choose from tailored, benchmarked options — matched to what each one cares about
Every recommendation is documented and defensible, not a judgment call
Coordination runs itself — your hours go back to your owners
The kind of service that keeps owners from shopping around
For vendors

Show up to work, not to haggle.

Good vendors don't lose on skill — they lose time. Time on quotes that go nowhere, on driving out to pin down a half-described job, on getting sized up by price instead of work. When the scope is clear and agreed before you commit, the day goes to the job — not to chasing it.

What you put up with today
01
Quotes that go nowhere

Most of what you bid, you don't win. The site visits and the write-ups still cost you a day — they just go to a job someone else lands.

02
A job nobody pinned down

The request is vague, so you show up to work out what it actually involves, then build in a cushion for whatever you can't see yet.

03
Sized up by price

Bids get read line by line. Fastest and cheapest tends to win the work — even when it isn't the careful option.

What changes with Baseline
today

Vague requests, a quote padded for everything you can't see, and a job won on price more than work.

with baseline

A clear, owner-approved scope before you commit, and a fair price agreed up front. You spend your time on the job, not on winning it.

Pre-scoped, owner-approved work — you know the real job before you commit
A price agreed before the work starts — no padding for the unknowns
Less time on quotes that go nowhere, more on the work you're actually doing
Do good work and it shows — your reputation travels across every PM on the network

Show up, do it right, and the next job follows. You earn the volume by being good — not by being the cheapest bid.

We never make the vendor the enemy. A clear, fair scope lines up owner and vendor — Baseline is just the ground both stand on.
