Property Management & Real Estate Development

The foundation of your property, from day one to done.

Onyx started because we couldn't find a property management company good enough for our own building — so we became one. Today we manage the day-to-day and build what comes next, for the same clients, under one roof.

Our story
"We approach management differently than what a typical board of directors and community members have become accustomed to — and we love sharing how." Angel-Marie Reiner, President, OCLM

Onyx was born out of necessity. During a successful real estate investment career, Eric Reiner decided to build a low-rise multi-residential apartment — overseeing the general contractor and the finances himself. When the building was ready, finding a property management firm that did the job right proved difficult.

So Eric and Angel-Marie, husband and wife, decided to manage it themselves. That was the start of a full-service property management company — now with more than 20 years of combined real estate, development and property management experience behind it.

Onyx Condo Management, the condominium side of the business, took on its first community in November 2019 — and grew 3,000% through the years that followed, including the pandemic, without stepping back once.

Why Onyx

What clients actually get, working with us.

01

We do what we say

We work hard to build trust — when we tell a client or a board we're going to do something, we do it. No exceptions.

02

Managers who aren't burnt out

Our property managers are not on-call after hours, on weekends or on holidays. Rested teams give better service — not less of it.

03

A licensed agent's eye on your investment

Eric Reiner is a licensed real estate agent — land opportunities often come to Onyx before they reach the open market.

04

Financing for capital projects

Onyx has lending options available to condo corporations that need to fund capital expenditures — not just advice on them.

What we do

Two disciplines, one point of contact.

Most owners and boards deal with a management company for the day-to-day and a separate contractor for anything bigger. Onyx does both — so nothing gets lost between the two.
