I would focus on finding one that is investment focused and a broker who can shop numerous lender platforms for you.

I was able to secure tenants for both units and used quite a bit of advice from this platform as well as other landlords I know.

Does it integrate well with other platforms?

There are a ton of valuable resources available on the platform, the knowledge here is boundless. 

This helps maintain clarity and ensures funds are used appropriately.To streamline rent collection and property management, consider using platforms like Apartments.com.

Everyone has their platforms that they love and swear by.

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. 

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

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

I can't know this for certain, of course.Not sure if this is worth pursuing with a lawyer or chalking this up to a lesson learned (be very careful buying properties in a wet area with finished basements, ensure it is suitably water-proofed).
