Multi family real estate is an asset type that is relatively easy to understand, underwrite, and add value to over time.

It’s been a long-time favorite for investors—from every day, hobbyist investors, to large institutional investors.

That requires a large variety of CRE professionals to service the sector, including appraisers, lenders, brokers, contractors, and more.

In short, real estate professionals of all kinds are looking for multi family business, and so they all want to find and get in contact with property owners.

Here, we’ll show you the best ways to find owners of multi family real estate and how you can access their contact information and win their business.

How to Find and Connect with Multi Family Property Owners

There are several ways to find multi family property owners.

Many of the free search functions depend on the property location.

Some municipalities provide robust property and ownership information online for anyone to search.

Other municipalities require people to submit formal requests for information, or require people to visit a clerk’s office to pull the records themselves.

Paid platforms like Reonomy or ProspectNow allow you to search and find multifamily property owners across the US and access their contact information.

Below, we’ll take a look at the different ways to locate multi family property owners in any US location—using public records, Reonomy, and a few other sources, like local chambers of commerce and brokerage firms.

Public Records Multi Family Property Owner Search

Many people will start a multi family property owner search by scouring the local public records.

Why? They’re free. And for a long time, they were actually the most reliable option.

If you have enough information on an owner, finding them through public records shouldn’t be a huge hassle.

Deeds and property assessment cards are generally the two public records sources that can piece you into the ownership behind a multi family property.

First, we’ll look at how to find those records.

Registry of Deeds

A deed is the legal document used to convey the ownership rights to a property. It usually contains the name of the seller (the Grantor) and the buyer (the Grantee).

The deed will specify the exact location of the property, the sales price, and the date the property was sold.

Deeds are considered public record and are usually recorded at the Registry of Deeds, or in some places, with the County Clerk.

Say you wanted to find out who owned a multi family property in Boston, Massachusetts.

You’d visit and then select “Suffolk” County. From there, you can search for deeds based on owner (or business) name, address, document type (in this case, deed) or by date the document was recorded.

Tax Assessor

Depending on the location, property taxes are collected at either the local or county level. The taxing authority generally posts property tax records online for public viewing.

These records are usually discoverable by property address. Once you locate the property address, the assessor’s database will usually indicate the owner of that property.

In the example below, we see the assessor’s card indicates 399 Congress LLC is the owner of record for the property at 399 Congress St, Boston.

In order to find out the true owner of this multi family property, you’d then need to take your search one step further to find out who the individuals are behind the LLC, which usually requires searching the state’s business database.

You could also use a tool like Reonomy to see LLC owners and their contact information (more on that later).

Building Department Records

Another way to find multi family property owner information is to search the local building department’s records.

For instance, say a commercial solar panel installer is interested in drumming up business amongst the owners of new multi family properties with at least 50 units.

One way to do so is by searching building department records to see what permits have recently been issued.

If there is a new permit for a building type that meets that description, then the contractor can reach out to whomever the owner is listed on the approved building permit.

Local Chambers of Commerce

You can also identify multi family property owners by reaching out to the local Chamber of Commerce near the subject property.

Many commercial real estate owners are involved in their chambers, and the chamber may be able to point you in the right direction if you’re trying to connect with a specific multi family property owner.

Commercial Property Owners Database

If you’d like more detailed search options, and more information on individual owners, you can turn to a commercial property owners database like Reonomy or ProspectNow.


The Reonomy Platform can be used to do the following:

  • Search multi family property owners by name and/or address
  • Discover property owners based on their asset’s sale, debt, and tax history
  • Discover property owners based on the size and age of their asset(s)
  • Pierce LLCs and access the contact information of true property owners

All of this can be done in any US county, for any asset type that’s not a single-family home.

You can filter a search for a number of different multi family sub-classes, including duplexes, triplexes, mobile home parks, nursing homes, dorms, frat/sorority houses, and more.

On top of what is mentioned above, the Reonomy Platform allows you to thoroughly research properties and owners off-market to see whether they might be:

It’s also in the same place as where you can find property owner phone numbers, email, and mailing addresses.


ESRI has a robust GIS mapping tool that can help commercial real estate professionals identify trends, patterns and opportunities that would otherwise be difficult to uncover.

For instance, GIS can provide valuable information about how a property is performing relative to its peers.

If an apartment building is leasing for lower rates than its surrounding competitors, maybe this is an opportunity for a property manager to pitch their business and help the owner reposition the property for greater success.

PolicyMap is another useful mapping tool. Users can layer on different sets of data within a specific geography.

Properties in pre-foreclosure are often in need of several services, from better property management to attorneys, new property managers and more.
