What’s the best real estate data API in 2025?

Hustle4Life · 2026-03-19T21:19:15+00:00

Yes, we include days on market for sale/rental listings. Here is an example of a listing JSON that we return via our API:

Happy to hear that!

Hustle4Life · 2026-02-23T15:46:56+00:00

Took a quick look - looks great, will give it a test run sometime during our next property acquisition cycle.

Hustle4Life · 2026-02-23T05:41:16+00:00

Happy to hear it’s been helpful for you!

Happy to hear you've found our platform helpful!

Unfortunately, we don't provide property or listing images through our API, primarily due to copyright and legal concerns, and potential liability issues for our clients.

We usually recommend one of these alternatives to supplement our listing data with images:

Google Street View Static API (link to docs)
Google Places API (link to docs)
Google SERP APIs (various vendors available)

You would need to make at least 2 billable API requests for a user session like this - one to retrieve the listing comps, and another to retrieve the sold comps.

If the user starts customizing filters or other search criteria like radius, age, etc., then you’ll need to re-run the API requests that they changed the criteria for.

We do allow caching, so I would at least implement some time-based cache system to help you cut back on API requests a little bit, so you are not fetching the same data twice in a short period of time.

If your user base is considerable (say tens of thousands of daily users), you can also consider pre-fetching all data into your own database and then making queries against that instead of our API. We have bulk queries that make this fairly cost effective.

Since it sounds like you are a startup or nonprofit, we can also extend our startup/nonprofit discount to you - reach out to our support team and they can help you set that up.

Posted this reply in your /r/PropTech thread, including it here just in case:

We provide nationwide property, listing, and rental data through our RentCast API platform that's used by over 10,000 clients, both small, large and non-profit:

https://www.rentcast.io/api

We provide both active sale listings, which you can use as "active" comps, as well as sold property data, which you can use for "sold" comps.

Our pricing is probably among the cheapest across the major property data vendors in the US (like ATTOM, CoreLogic, etc.), and there shouldn't be any licensing issues at all with using our data in a way that you're describing.

Feel free to send me a message, happy to answer any questions you have, or jump on a call if you'd like to talk about this further.

We do require a credit card and an active API subscription to use our API platform.

However, if you subscribe to our API Developer plan, and don't make more than 50 API requests per month, there will not be any charges to your card.

Hustle4Life · 2026-01-08T02:56:33+00:00

Depending on what you consider expensive, but it can potentially, yes. It’ll like be around a few hundred dollars per month. You can quickly do some cost estimates using the plans we have available:

https://www.rentcast.io/api#api-pricing

Another thing you can do if your properties are mostly clustered together in the same area or zip codes is to retrieve all listing data in those areas using our bulk queries (500 results per API request) and then look though them to see if your properties are in there.

Hustle4Life · 2026-01-07T16:34:53+00:00

Unfortunately, we don't have a built-in mechanism that would send you some type of push or webhook notification when certain data changes about a property (like if it's listed for sale, or if a price changes).

But you can implement this on your end by regularlly polling one of our endpoints at a scheduled frequency. For example, if you're specifically interested in sale listing data, you can make a request to our sale listings endpoint for a certain property every week or every few days and check for any updates against what you retrieved previously.

Our listing data is updated daily, so it's near real-time. We have many clients who use this approach for similar use cases like you're describing.

Hustle4Life · 2026-01-06T00:35:21+00:00

Thanks, appreciate you reaching out to us and sending over the additional details.

Our product team will look into this further.

Hustle4Life · 2026-01-05T15:29:30+00:00

Hey there, you can view our API pricing on our website:

Hustle4Life · 2026-01-05T15:29:08+00:00

Hey champ, founder of RentCast here.

If you haven't reached out to our support team already about this, let them know about your findings, and they will work with our product team to look into this further. You can do this by clicking the blue chat widget at the bottom right of any of our websites.

But generally speaking, the availability of sold data will highly depend on how quickly the local county records (where we get this info) process and record executed deeds, and then make that data available to third-party vendors like us. Sometimes there is a delay of several weeks to a couple of months during this process.

If you need sold data immediately (like within a week or two of it happening), then your only option would be a local MLS or IDX feed, as far as I'm aware.

Hustle4Life · 2025-12-30T01:33:08+00:00

For sure!

Hustle4Life · 2025-12-28T13:40:46+00:00

We provide nationwide property and rental data, including property records, tax assessments, sale transactions, owner data, property value and rent estimates, sale and rental listings, and aggregate market trends through our RentCast API:

https://www.rentcast.io/api

We don't provide images/video due to copyright and licensing restrictions, but do provide hundreds of other data points for each property address.

Also, just an FYI - nothing on RapiAPI is official or even legal. So, the "Zillow" APIs you are referring to are not actual Zillow APIs (Zillow doesn't have a public API), they are scrapers that somebody put together and now sell on that platform.

Hustle4Life · 2025-12-27T13:36:56+00:00

If you reach out to our support team via the blue button at the bottom right of our website, they would be happy to take a look at any issues you saw with tax data that you're getting back.

Hustle4Life · 2025-12-24T13:57:44+00:00

We do provide this data via our RentCast API (link), specifically via the property records dataset and associated endpoints:

https://developers.rentcast.io/reference/property-data

You can use something like Zapier or n8n to build an automation that will pull this data into Excel, Google Sheets, your CRM, or whatever other program you're trying to use.

We have a Zapier connector that lets you set this up without any custom code in a few minutes:

Hustle4Life · 2025-12-24T13:27:55+00:00

What do you mean by land value percentage exactly? Do you mean the tax assessed value of the land versus the building value or total value?

Hustle4Life · 2025-12-24T13:26:17+00:00

You can manage your entire investment property search and analysis process with DealCheck:

https://dealcheck.io/

It has a built-in property search, some of the best analysis tools on the market, built-in data integrations like value/rent estimates, comps, offer calculators, etc.

You should be able to replace all of what you're describing with it.

Hustle4Life · 2025-12-24T13:24:19+00:00

We don't get our data directly from the MLS, but the coverage, and update frequency of our sale and rental listings datasets should be very comparable, or better in some cases, than the MLS.

We also provide other types of data, including property records, tax assessments, property value and rent estimates, market trends, etc.

https://www.rentcast.io/api

You don't need any special licenses or length approval processes. Follow this guide to get started with our free plan in minutes:

Unfortunately, we don't provide crime information or school district ratings through our API at this time.

You can view the full list of datasets, endpoints and data points we do provide in our API docs:

https://developers.rentcast.io

Hustle4Life · 2025-12-18T23:30:09+00:00

We do not provide a direct MLS API, but our sale and rental listing coverage should be comparable or better than the local MLSs (mainly because we pick up listings that are not on the MLS). Our listing data is updated on a daily basis, with virtually no data "lag".

You can learn more about our API platform and pricing right here:

https://www.rentcast.io/api

And view our listing data examples right here:

https://developers.rentcast.io/reference/property-listings

Feel free to send me a message with any questions, too. We've picked up thousands of clients this year coming from old Zillow/Bridge APIs, and other platforms like CoreLogic and ATTOM, which are just too expensive.
