If you work with commercial real estate listings, the hard part is not always finding properties.

The hard part is turning listings into a file someone can actually use.

Two tabs are open:

Then the manual work starts:

  • copy listing URLs
  • normalize property names and addresses
  • remove duplicates
  • compare asking price and rent fields
  • check whether cap rate is stated or missing
  • look for broker names and companies
  • keep source links so someone can verify the row later

That is the difference between a listing portal and a market file.

One helps you browse.

The other helps you review.

What a useful CRE CSV actually needs

A basic export with only title, price, and URL is usually not enough.

For first-pass commercial real estate research, I want each row to answer a few questions quickly:

Question Field examples
What is the asset? address, city, state, asset class, subtype
Where did it come from? source, listing URL, source ID
Is it sale or lease? transaction type, asking price, rent per sqft/year
Is the financial context usable? cap rate, cap-rate source, NOI when available
Is it fresh or stale? days on market, listed date, enrichment status
Who is attached to it? broker name, broker company, public phone/email when available
Is it duplicated? also listed on, duplicate signals, dedup key

The important part is not making the file look clean.

The important part is making the row explain itself.

Why LoopNet + Crexi can be messy together

Using both sources is useful because coverage is not identical.

But combining them creates a second problem: the same property can appear in slightly different ways.

For example:

123 Main St
123 Main Street
123 Main St., Suite 400
123 Main Street - Office Building
Enter fullscreen mode Exit fullscreen mode

Technically, those are different strings.

In a market file, they may be the same property.

That is why a good commercial real estate CSV export should preserve source links and duplicate signals instead of pretending the data is perfect.

A cleaner workflow

The workflow I like is:

  1. Pick a market: Dallas, Los Angeles, Houston, Phoenix, Austin, etc.
  2. Pick transaction type: sale, lease, or both.
  3. Pick asset classes: office, retail, industrial, multifamily.
  4. Pull public listing rows from LoopNet and Crexi.
  5. Normalize common fields into one schema.
  6. Add duplicate signals across sources.
  7. Add cap-rate and days-on-market context where available.
  8. Keep broker fields best-effort, not overpromised.
  9. Export to CSV, Excel, JSON, or API.

The output should be boring in the best way:

address_full
city
state
source
transaction_type
asset_class
asking_price_usd
asking_rent_per_sqft_per_year_usd
cap_rate_normalized
cap_rate_source
days_on_market
broker_name
broker_company
broker_phone
broker_email
also_listed_on_text
enrichment_status
listing_url
Enter fullscreen mode Exit fullscreen mode

Example Apify input

I packaged this workflow as an Apify actor because Apify already gives you runs, datasets, schedules, exports, and API access without building a full app first.

Example input:

{
  "city": "Dallas",
  "state": "TX",
  "sourcesEnabled": ["loopnet", "crexi"],
  "transactionTypes": ["sale", "lease"],
  "assetClasses": ["office", "retail", "industrial", "multifamily"],
  "maxResultsPerSource": 500,
  "includeListingDetails": true,
  "deduplicate": true,
  "normalizeCapRate": true,
  "monitoringMode": false,
  "downloadImages": false
}
Enter fullscreen mode Exit fullscreen mode

The actor is here:

Commercial Real Estate Brokerage Intel

It is designed for first-pass public listing research, not as a full CRE platform replacement.

CSV vs API

CSV is usually the right first export.

It is easy to review, send, upload to Google Sheets, or drop into a CRM.

API access becomes useful when the workflow repeats:

  • daily CRE deal-flow monitoring
  • internal dashboards
  • lead routing
  • enrichment pipelines
  • market-by-market research

That is why I think of the product as a market-file engine first, and an API second.

The buyer usually wants the file.

The developer wants the repeatable workflow behind it.

A few caveats

Public listing data is not perfect.

Broker phone and email fields depend on what the source exposes publicly. Cap rates can be missing or estimated. Days-on-market may not exist for every row. Some rows should stay marked as search-only if detail enrichment is blocked or unavailable.

That is why I like exposing fields such as:

cap_rate_source
enrichment_status
also_listed_on_text
listing_url
Enter fullscreen mode Exit fullscreen mode

Hiding uncertainty makes the output look cleaner.

Showing uncertainty makes it more useful.

FAQ

Can you export LoopNet and Crexi listings to CSV?

You can build a workflow that turns public LoopNet and Crexi listing searches into a structured CSV, but the quality depends on normalization, deduplication, and source provenance.

Is there a commercial real estate listings API?

There are multiple real estate data APIs, but if your workflow is specifically public LoopNet + Crexi first-pass research, an Apify actor can be a lightweight way to produce CSV, Excel, JSON, and API outputs from the same run.

What fields should a CRE market file include?

At minimum: address, city, state, source, listing URL, transaction type, asset class, price or rent, square footage, cap-rate context, days-on-market when available, broker fields when public, duplicate signals, and enrichment status.

Should this replace deeper underwriting or paid CRE platforms?

No. This is better used before deeper analysis: a first-pass market file that helps decide which listings deserve attention.
