Everyone has their platforms that they love and swear by.

BiggerPockets is a valuable platform for learning about real estate investing, networking, and gaining insights.

With so many resources available, 100% financing programs, down payment assistance programs, urban development programs, places where sellers are begging you to buy their homes, and platforms like this for free training and guidance why do so many people who want to get in REI fail to actually get their first home under contract. 

As with any platform, users need to filter through the information critically.

I would just search up @Buildyourhideaway on any social media platform. 

The only drawback I found so far is that many of the numbers are on the do not call list, but that's not a problem with the platform.

What platform or service do you use to find owner's phone number for cold calls?

Anna, you can also check out Youtube, Podcasts  and there numerous other Social Media platforms that also discuss this topic.

Are there better platforms?

BiggerPockets now has a featured property management search option on the platform.
