Cash Buyers Search

These would be properties that look like they were all cash transactions.

{
  "cash_buyer": true
}

Private Lenders Search

These would be properties where it looks like the deals were completed by a private/hard money lender

{
  "private_lender": true
}

Investor Buyers Search

Similar to cash_buyer, this adds an additional filter to only include properties where the buyer has a different mailing address than the property.

{
  "investor_buyer": true
}

For more deterministic searching:

Properties Owned Search

Find larger or institutional buyers using our linked properties and properties owned searches.

properties_owned_min: [some number]
This will bring back properties where the current owner has a portfolio of properties greater than or equal to the number you specify.

You can couple that with
properties_owned_max: [some maximum number of properties owned]
This will allow you to create a range if say you want to focus on smaller landlords that aren't hedgefunds. Or the reverse - find potential hedge fund buyers by setting the minimum number higher.

{
  "properties_owned_min": 10,
  "properties_owned_max": 50
}

In either case, inspect the linkedProperties object to get total portfolio value as well.

for (let result of results) {
  console.log('linked properties: ', result.linkedProperties);
}

Flipped Property Buyers

You can also filter on possible flips by searching based on how long the prior owner owned a property:

{
  "prior_owner_months_owned_min": 6,
  "prior_owner_months_owned_max": 18
}

You can combine this with sales that occurred recently to try to find prior owners who meet this criteria.
last_sale_date_min: [set to some recent date 'YYYY-MM-DD']
You'd inspect the salesHistory object to get the prior owner's information.

So you can look at sales within a given window to try and determine flips.

Active Buyer Discovery through Linked Properties

Search for active buyers by looking at linked properties' sale dates within the last 6 and 12 months.

{
  "size": 50,
  "state": "OK",
  "portfolio_purchased_last12_min": 5,
  "portfolio_purchased_last12_max": 10
}
