Unit Selector Companies in New York (2026)

Quick answer: New York buyers think in lines rather than floors. Every unit in the 05 line shares a layout, aspect and view corridor and differs only in height and price, so a buyer interested in 1205 is interested in 1505 and indifferent to 1206. Selectors organised floor by floor fight that, and reorganising by line is a structural decision rather than a styling one.

New York runs the most structurally complex residential sales market in the country, and unit selectors here have to accommodate conventions that exist almost nowhere else.

Three of those conventions change what the tool should do, and none of them are aesthetic.

An honest note about local vendors

As in other markets in this category, we did not identify a meaningful New York based unit selector vendor market, and we are not going to present national platforms as local.

The reason is structural. Inventory systems and selectors are software built from unit schedules and drawings, and the tooling does not vary by geography the way architectural rendering does, where local knowledge genuinely affects the output.

What varies here is what the tool has to model, and New York has requirements most markets do not. That is where this guide concentrates.

How this list was put together

Entries are platforms serving this market. None is presented as New York based, because none of the ones we identified are.

Criterion	What we looked for
Line organisation	Whether vertical stacks can be a primary axis.
Contract to closing	Whether the long gap between them is modelled.
Release and amendment	Whether pricing history is preserved.
View and exposure data	Whether the attributes that drive price 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.

1. MRI Software

MRI leads for New York because condominium sales here are structurally complex in ways that reward a purpose built system rather than a configured one.

A New York condo offering runs on a plan with defined units, a schedule of prices that changes by amendment, closing structures that vary, and a sales pipeline where contract signing and closing are separated by long periods during construction. Modelling that properly is exactly what condo sales platforms exist for.

Where it fits: sponsor sales teams running a building through an extended sell out. Where it stops: the buyer-facing display, which is functional and sits awkwardly inside the marketing standards this market expects.

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 presentation, produced alongside the plans and renderings it displays and connected to whichever system holds the inventory.

New York has a characteristic that changes how a selector should be organised, and almost no tool handles it natively: buyers here think in lines rather than in floors.

A New York building is understood as a set of vertical stacks. The 05 line, the 08 line, the corner line. Every unit in a line shares a layout, an aspect and a view corridor, and differs only in height and price. A buyer who liked 1205 is interested in 1505 and 905, and completely uninterested in 1206.

Selectors organised floor by floor make that natural search awkward, because they present a horizontal slice of a building people navigate vertically. Organising by line, with floors as the secondary axis, matches how the market actually thinks and it is a structural decision rather than a styling one.

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. RE.Platform

Built around phased releases, pricing evolution and delivery timelines, which describes New York condominium sales accurately.

Sponsor sales here typically release in tranches with escalating pricing, and a system that models the release history rather than only current state preserves the record that reporting and amendments depend on.

4. Property xRM

The granular state model is unusually relevant in this market because the gap between contract and closing is long and commercially significant.

A unit in contract during construction is neither available nor closed, and a system with only two states forces that distinction into a spreadsheet, which in a market with this much at stake per unit is a real exposure.

5. Sell.do

CRM with pricing management treated as a first class capability, which matters where prices are set out in a schedule and adjusted by formal amendment rather than casually.

The discipline of tracking what price applied when is worth more here than in markets where pricing is informal.

6. Zoho CRM

The pragmatic answer for smaller sponsors and boutique buildings, where a purpose built platform is more system than a twenty unit conversion requires.

New York has a substantial market of small buildings and conversions where the sales operation is two people and a well configured general CRM handles the inventory adequately.

7. YourNextHome

Focused inventory management without enterprise overhead, suited to mid sized New York projects that need structure rather than scale.

Buildings are navigated by line, not by floor

The single most useful thing to understand about a New York selector, and the thing generic tools get wrong.

A New York apartment is identified by floor and line: 12B, 1405, 8C. The letter or number after the floor identifies the vertical stack, and every unit in that stack shares a footprint, an orientation and a view corridor.

That makes the line the meaningful unit of comparison. A buyer who has seen 1205 and found the layout right is looking for the same layout higher or lower, at a different price. They are not comparing it against 1206, which faces a different direction and has a different plan.

A selector organised as a stack of floors, showing every unit on each level, presents information the buyer has to reassemble mentally. A selector organised by line, with the option to move up and down within it, matches the search.

The practical implication is that line should be a first class attribute in the schedule and a primary navigation axis in the interface, which is a design decision that has to be made deliberately because no platform defaults to it.

Exposure and light drive price more than area

In most markets area and bedroom count dominate pricing. In New York exposure frequently matters more, and buyers are precise about it.

North, south, east and west are not equivalent. Southern exposure carries a premium for light. Northern light is preferred by some buyers for consistency. A unit facing a blank wall across a narrow lot line is worth substantially less than one facing an open street, regardless of identical square footage.

This vocabulary is used fluently by buyers and brokers here, and a selector that omits exposure is missing the attribute that explains its own pricing.

Related and equally important is what the unit actually faces: an open avenue, a courtyard, an adjacent building at close distance, or a protected view over lower buildings. That is a description rather than a data field and it belongs on the unit view.

The contract to closing gap

A structural feature of new development sales here that selectors routinely fail to model.

In a new condominium, a purchaser signs a contract long before closing, sometimes years, while construction completes. During that period the unit is not available and not closed. It is in contract.

For the sponsor that distinction matters commercially: contracted units support financing milestones, closed units release proceeds, and the two are reported separately. For the public selector, showing in contract units as simply sold is usually correct and showing them as available is a serious error.

The failure happens when a system models only two states. The sales team then tracks contracts separately, and the parallel record is where the errors enter, in a market where the value per unit makes an error expensive.

Condominium and cooperative are different products

Worth noting because it affects what a selector is even for.

New development sales are overwhelmingly condominium, and unit selectors serve them naturally: a sponsor with defined inventory selling to buyers.

Cooperative apartments are resales through brokers, with board approval as a step no tool models, and there is no inventory in the developer sense. A selector has no role there, which is worth stating because searches conflate the two.

The relevant boundary for anybody publishing a selector is that it presents a sponsor's inventory. Approval processes, whether board or otherwise, sit outside it entirely, and no tool or vendor influences them.

What a New York selector should contain

Line as a primary axis. With movement up and down within a stack.

Exposure on every unit. Stated in the vocabulary buyers use.

What the unit faces. Described rather than implied, including close lot line conditions.

In contract as a distinct state. Separate from available and from closed.

Ceiling height by floor band where it varies. A genuine differentiator in many buildings and frequently omitted.

Outdoor space stated separately. Terraces and balconies are scarce enough here to be priced individually.

Two mistakes specific to this market

Organising by floor when buyers think in lines. The tool works and fights the way the market searches.

Collapsing in contract into sold. Acceptable publicly and damaging internally, because the sponsor needs the distinction and will maintain it somewhere else if the system cannot.

Brokers change how the tool gets used

New York sales run through brokers to a degree few markets match, and that changes who the selector is actually serving.

A substantial share of traffic is agents checking availability for a client, frequently while on the phone or between showings. They want a fast, accurate answer rather than an experience, and they will abandon a slow tool immediately because they have a client waiting.

They also forward things. A broker who finds a suitable unit sends it to their client, which means every unit view needs to work as a standalone link with the address, the unit, the line, the price and the plan visible without context.

Designing for the broker rather than only for the end buyer is a meaningful shift in this market, and it usually means favouring speed, deep linking and printable or forwardable output over depth.

Neighbourhood and building context

A New York specific point about what belongs on the unit view.

Buyers here are choosing a neighbourhood at least as much as an apartment, and frequently know the area better than they know the building. What they want from the tool is where this unit sits within a building whose location they already understand.

That argues for less emphasis on selling the location, which the broker and the neighbourhood do, and more on the building specific facts: which line, which exposure, what it faces, what floor, ceiling height, outdoor space.

It is the opposite emphasis from a suburban masterplanned community, where the location is the product and the map has to sell it. In New York the location is assumed and the unit specifics are the whole conversation.

What to send a vendor for a New York building

The general unit selector input list applies, with additions this market makes necessary.

The unit schedule organised by line rather than only by floor, with the line identifier as an explicit field. Exposure for every unit. A description of what each line faces, including any close lot line conditions. Ceiling heights by floor band where they vary. Outdoor space stated separately by unit. And the state list including in contract as distinct from closed.

Add the offering plan unit designations if they differ from the marketing names, because they will appear in contracts and the mapping between the two needs to exist somewhere durable.

Frequently asked questions

Why do New York selectors need to be organised by line?

Because buyers think vertically. Every unit in the 05 line shares a layout, aspect and view corridor, differing only in height and price, so somebody interested in 1205 is interested in 1505 and indifferent to 1206.

Why does exposure matter more than area in New York?

Because light and outlook drive pricing here in a way square footage does not. A unit facing a blank wall across a narrow lot line is worth substantially less than one facing an open street at identical size, and buyers use that vocabulary fluently.

What is the in contract state and why does it matter?

In new development, purchasers sign contracts long before closing while construction completes. The unit is neither available nor closed. Sponsors report the two separately, and systems modelling only two states force that distinction into a spreadsheet.

Do unit selectors work for cooperative apartments?

No. Cooperatives are broker resales with board approval rather than sponsor inventory, so there is nothing for a selector to present. Approval processes sit outside any tool, and no vendor influences them.

Are there New York based unit selector vendors?

We did not identify a meaningful local vendor market. These are software products built from unit schedules and drawings, and the tooling does not vary by geography the way architectural rendering does.
