How to Find Property Management Companies by Location and Portfolio Size
Learn how to find property management companies by location and portfolio size for B2B sales. Practical methods using licensing data, real estate databases, and AI prospecting.
Founding AI Engineer @ Origami
There are over 300,000 property management companies in the US managing roughly $5 trillion in real estate assets. From a single landlord managing 10 units to firms like Greystar managing 800,000+ units, the range is enormous.
If you sell software, insurance, maintenance services, or marketing to property managers, you need a way to find the right ones — not just any company, but ones in your target geography with the right portfolio size.
Quick Answer: To find property management companies by location and portfolio size, use state real estate licensing boards (property managers need a broker's license in most states), the NARPM or IREM member directories, Google Maps filtered by location, and Origami to build enriched lists with portfolio size estimates, owner contacts, and growth signals. Cross-reference with apartment listing sites like Apartments.com to estimate portfolio size.
Why Portfolio Size Matters
A property manager with 50 units operates completely differently from one with 5,000. The tools they need, the budget they have, and the problems they face are different at every scale.
| Portfolio Size | Typical Operations | What They Buy |
|---|---|---|
| 1-50 units | Owner-managed, maybe one employee | Basic accounting, tenant screening |
| 50-200 units | Small team, dedicated office | Property management software, maintenance coordination |
| 200-1,000 units | Multiple staff, possibly multi-site | Full PM platform, accounting integration, vendor management |
| 1,000-5,000 units | Regional operation, multiple markets | Enterprise PM software, BI/analytics, compliance tools |
| 5,000+ units | National firm, institutional backing | Custom solutions, enterprise contracts |
Knowing the portfolio size before you reach out lets you lead with the right message and the right product tier.
Where to Find Property Management Companies
1. State Real Estate Licensing Boards
In most states, property managers must hold a real estate broker's license or a specific property management license. These databases are public and searchable.
How to use it:
- Find your target state's real estate commission website
- Search for licenses with "property management" designation
- Filter by city or county
- New licenses in the last 6 months indicate new or expanding companies
States with good databases: California (DRE), Texas (TREC), Florida (DBPR), New York, Georgia, Colorado.
2. Origami — Build Enriched Lists in Minutes
Tell Origami: "Find property management companies in Atlanta managing 100+ units. Include company name, estimated portfolio size, owner name, email, phone, and website."
The AI agents pull from real estate databases, business registrations, web scraping, and data providers to build a qualified list. You can add filters for property type (residential, commercial, HOA) or growth signals.
3. NARPM and IREM Directories
The National Association of Residential Property Managers (NARPM) and Institute of Real Estate Management (IREM) maintain member directories searchable by location. Members tend to be professional, established firms — good prospects for B2B sales.
4. Apartment Listing Sites
Apartments.com, Zillow Rental Manager, and similar platforms list the management company for each property. Scraping or manually reviewing these listings gives you a proxy for portfolio size — count how many properties each company manages.
5. Google Maps + Reviews
Search "property management company" in your target city. Google review count and rating give you signals about company size and reputation. A company with 200+ reviews is managing a significant portfolio.
Growth Signals for Property Management Companies
Strong signals:
- Hiring property managers, leasing agents, or maintenance coordinators
- Adding new properties or expanding to new markets
- Website showing new communities or properties
- Winning HOA contracts (often announced in board meeting minutes)
Moderate signals:
- Google review velocity increasing
- Social media activity picking up
- New certifications (CPM, RMP, MPM designations)
Track multiple signals. A property manager that's hiring AND adding new properties is in active growth mode.
How to Estimate Portfolio Size
This is the tricky part. Portfolio size isn't in a single database. Here's how to estimate it:
- Company website: Most PM companies list their properties. Count them.
- Apartment listing sites: Search the company name on Apartments.com and count listings.
- LinkedIn employee count: A rough proxy — 1 employee per 50-100 units is typical for residential PM.
- Revenue estimates: Data providers like ZoomInfo or Dun & Bradstreet estimate revenue. Divide by average management fee ($50-100/unit/month) for a unit estimate.
- Origami enrichment: The AI can estimate portfolio size by combining web data, employee count, and listing data.
Building Your Prospect List: Step by Step
Step 1: Define your target: geography, portfolio size range, property type (residential, commercial, HOA, student housing).
Step 2: Pull from state licensing databases. Export company names and locations.
Step 3: Enrich with portfolio size estimates using the methods above.
Step 4: Add decision-maker contacts — owner, VP of Operations, or Director of Property Management.
Step 5: Score by fit. Portfolio size in your sweet spot + growth signals = top priority.
Step 6: Outreach with specificity:
"Managing 300+ units across multiple communities is where most PM companies start needing [your solution]. Noticed you've been adding properties in [area] — is [pain point] becoming an issue yet?"

FAQ

How do I estimate a property management company's portfolio size? Count properties listed on their website and apartment listing sites, check LinkedIn employee count (roughly 1 employee per 50-100 units), and use revenue estimates from data providers. Origami can automate this estimation.
What's the best way to prospect property management companies? Lead with portfolio-specific pain points. A 100-unit company has different problems than a 1,000-unit company. Reference their growth, specific properties, or market conditions to stand out from generic outreach.
How many property management companies are there in the US? Over 300,000, ranging from individual landlords to national firms. The market is highly fragmented, with the top 50 firms managing only about 10% of total rental units.
What signals indicate a property management company is growing? Adding new properties, hiring leasing agents or maintenance staff, winning HOA contracts, expanding to new markets, and increasing their web/marketing presence. Multiple signals together indicate strong growth.
