Best Unit Selector Companies (2026)

Quick answer: A unit selector is two things bolted together. The inventory layer decides what is true, which belongs in a system of record with permissions and an audit trail. The presentation layer decides what a buyer understands, which is a design problem. Buying one and expecting both is the source of most disappointment in this category.

Unit selectors look like a visualization product and behave like an inventory system, which is why so many of them are beautiful at launch and wrong by the end of the quarter.

The visible part is a building or a plan where a buyer clicks a unit and sees its details. The part that determines whether it works is underneath: where the availability comes from, who is allowed to change it, what happens when two people want the same apartment, and how prices that move every quarter stay current.

This guide is organized around that division, because choosing well means recognising which half of the problem you are solving.

How this list was put together

Entries were identified through public research and are reachable products. We deliberately include inventory and CRM platforms alongside presentation vendors, because the category is routinely compared as though those were the same purchase.

Criterion	What we looked for
Layer	System of record, presentation, or both.
State model	How many availability states are supported.
Pricing handling	Whether price evolution and bands are modelled.
Release management	Whether phased releases are supported.
Stated limits	Where each option stops being the right answer.

Editorial note: Rendimension publishes this guide and appears on it. We place an inventory platform first because a system of record and a presentation layer are not substitutes, and we list ourselves in the specific niche we serve rather than at the top. Every other entry is an independent company we do not control, identified through public research.

1. MRI Software

MRI Software leads because a unit selector is the public face of an inventory problem, and this category is where that problem is actually solved rather than displayed.

Condo sales platforms handle what the selector cannot: release phases, holds and reservations with expiry, contract stages, price list versioning, and the prevention of two agents selling the same unit within an hour of each other.

Where it fits: developers running structured sales with a team, multiple releases and a pipeline that needs tracking. Where it stops: it is a system of record rather than a marketing surface, and the buyer-facing presentation it produces is functional rather than designed.

Listed first because a system and a presentation layer are not competing purchases, and putting a rival production vendor above ourselves would be dishonest in the other direction.

2. Rendimension

Second, in the niche we serve: the buyer-facing selector and availability map, produced alongside the plans and renderings it presents and connected to whichever system owns the inventory.

The distinction we would draw for anybody comparing this category is that a unit selector is two things bolted together, and most disappointment comes from buying one and expecting both.

The inventory layer decides what is true: which units exist, what state each is in, what it costs today, who is allowed to hold it. That belongs in a system of record with permissions and an audit trail.

The presentation layer decides what a buyer understands: which unit is which, what the view is, how the layouts differ, why one costs more than another. That is a design and visualization problem and it is what we produce.

Building the second without connecting to the first gives you a beautiful display of stale data. Buying the first and using its default output gives you accurate data nobody enjoys reading. Most projects need both, from different suppliers, wired together deliberately.

Declared terms rather than claims: first visuals in 48 to 72 hours, plan sets in 5 to 7 days, and reasonable revisions included at no extra charge. We do not raise capital, we do not obtain approvals and we do not guarantee them, and we do not sell units or operate a sales CRM.

3. Sell.do

Sell.do covers unit management, availability tracking, pricing management and real-time inventory updates within a broader real estate CRM.

The pricing management component is worth attention because it addresses something selectors handle badly on their own. Prices in pre-construction do not sit still: they rise through releases, they vary by floor band and view, and incentives change quarterly. A selector reading from a static price list is wrong within weeks.

Suited to developers who want the sales pipeline and the inventory in one system rather than reconciling two.

4. Property xRM

Property xRM emphasises a real-time view across vacant, blocked and soon-to-be available units, which is a more granular state model than most selectors implement.

That granularity matters. Available and sold are the two states every tool has, and the interesting ones sit between: held pending deposit, reserved with an expiry, contract exchanged but not completed, released for a broker event but not public.

Developers who model only two states discover that their sales team maintains the real picture in a spreadsheet alongside, which is where double bookings originate.

5. RE.Platform

RE.Platform addresses phased releases, pricing evolution over time and construction progress affecting delivery timelines, which is a precise description of what makes pre-construction inventory hard.

Those three variables interact. A unit released in phase two at a higher price with a delivery date that slipped is a different product from what the phase one price list described, and a selector that flattens that presents the development inaccurately.

Relevant for developers whose sell out runs long enough that all three change during it, which is most of them.

6. Blindersoe

Blindersoe combines floor-wise inventory, bookings and construction updates with CRM and content management in one platform.

The construction update integration is the distinguishing element, connecting build progress to what a buyer sees, which for buildings sold years ahead of completion is genuinely useful and rarely joined up.

7. YourNextHome

YourNextHome offers inventory management aimed at residential developers as a focused product rather than a full enterprise platform.

Reasonable for developers who want structured inventory without adopting a large system, which describes a substantial share of mid sized projects.

8. Zoho CRM

A general CRM configured for real estate inventory, with units as structured records carrying status, hierarchy and attributes tied to sales activity.

Included because it is the honest answer for a large number of developers: a capable general system, configured well, frequently outperforms a specialised product used badly.

The tradeoff is configuration effort and the absence of real estate specific conventions out of the box, which means somebody has to design the data model rather than inherit one.

The two layers, and why they get confused

The inventory layer

Decides what is true. Units, states, prices, holds, reservations, contract stages, release phases, permissions and history.

It needs to be authoritative, which means one system rather than several, with rules about who can change what and a record of who changed it when. This is a business systems problem and it belongs with sales operations.

The presentation layer

Decides what a buyer understands. Which unit is which within the building, how layouts differ, what the view is, why one floor costs more, how to compare two options.

It needs to be clear and persuasive, which means design, plans and imagery. This is a marketing problem and it belongs with whoever produces the rest of the sales material.

The confusion happens because both are sold as unit selectors. A CRM vendor demonstrating their availability display and a visualization studio demonstrating their selector appear to be showing the same product, and they are showing two halves of it.

The state model is where selectors fail

Every selector supports available and sold. The failures live in the states between them.

Held. A verbal hold with no money attached, which sales teams grant routinely and which no selector models. It is why the spreadsheet exists.

Reserved. A deposit taken with an expiry date. If the expiry is not modelled the unit stays reserved indefinitely and inventory quietly shrinks.

Contracted, not completed. Sold for practical purposes and not yet closed, which matters for reporting and for what happens if it falls through.

Released and unreleased. Units that exist but are not yet for sale. Showing them as unavailable and showing them as nonexistent send very different signals to a buyer assessing whether a building is selling.

Broker or preview allocation. Available to some audiences and not others, which a public selector has to handle without leaking the distinction.

Developers who model two states end up with the real picture maintained manually alongside, and that parallel record is where double bookings come from.

Pricing does not sit still

The second structural problem, and the one that makes static selectors wrong fastest.

Pre-construction pricing rises through releases by design, varies by floor band and view within a release, and is adjusted by incentives that change quarterly and are frequently not published. A selector reading a price list exported at launch is describing a building that no longer exists commercially by month three.

The workable approaches are to drive pricing from the system that owns it, to show price bands rather than exact figures with an enquiry route, or to show no pricing at all and route to a person. All three are defensible. What is not defensible is showing a specific number that stopped being true in the spring.

One boundary worth stating

Unit selectors support a sales process by removing its slowest exchange. They do not sell units, they do not obtain approvals and no vendor obtains approvals or can guarantee them, and they do not replace a sales team or a system of record.

What they do is let a buyer see what exists, what is available and what it costs, at the moment they are interested, provided somebody has made sure those three things are true.

Where selectors are used beyond condo sales

The pattern generalises anywhere a fixed set of units is sold or let from a shrinking pool.

Multifamily leasing. Availability turns continuously rather than depleting, which inverts the model: units come back rather than disappearing, and the selector has to handle a cycle rather than a countdown.

Student accommodation. Annual cycles with a compressed booking season, where the entire inventory turns over in weeks and availability accuracy matters enormously for a short window.

Storage and parking. High unit counts, low individual value, frequent turnover, and a selector that has to be fast rather than persuasive.

Marina berths and pitches. Fixed inventory with strong position premiums, closest in behaviour to condominium sales.

Office suites in serviced buildings. Sold per desk or per suite with short terms, which combines leasing turnover with unit-level selection.

What good selectors do that poor ones do not

Five differences, observable in a few minutes of use.

They show state honestly. Sold and reserved visible rather than removed, so a buyer can read how the building is selling.

They filter before they display. Buyers narrow by price, bedrooms and floor before they browse, and requiring a click per unit to discover those defeats the first task.

They fail safely. When data is stale or a connection breaks, they say so or route to enquiry rather than showing a confidently wrong price.

They carry a timestamp. Availability as of a stated moment is more trustworthy than availability presented as eternal truth.

They lead somewhere. A buyer at the point of selecting a unit is at peak interest, and a selector with no next action wastes it.

Frequently asked questions

What is the difference between a unit selector and an inventory system?

The inventory system decides what is true: states, prices, holds and permissions, with an audit trail. The selector decides what a buyer understands: which unit is which, how layouts differ, why one costs more. They are different purchases that get compared as one.

Why do unit selectors show wrong availability?

Usually because they model only available and sold, while sales teams work with holds, reservations with expiry, contracted units and unreleased inventory. The real picture ends up in a spreadsheet alongside, and that parallel record is where double bookings originate.

How should pricing be handled?

Drive it from the system that owns it, show bands rather than exact figures, or show no pricing and route to a person. All three work. Showing a specific number exported at launch does not, because pre-construction prices rise through releases and change with incentives.

Should unreleased units be visible?

It is a deliberate choice. Showing them as unavailable and omitting them entirely send different signals to a buyer assessing whether a building is selling well, and the decision should be made rather than defaulted.

Can one vendor supply both layers?

Some platforms cover both, with functional rather than designed presentation. Most projects end up combining a system of record with a separately produced presentation layer, wired together deliberately rather than by accident.
