I suggest using a service like Mayistay.

Here are a few suggestions on how you can maximize the wealth of information available: Check out the blogs and podcasts, or take advantage of the search feature (magnifying glass).

I've seen a few instances on the biggerpockets youtube channel where the comments were suggesting the data used in calculations wasn't accurate.

If you are looking to be an investor then I would suggest you don't be an agent that is a poor mans game and it will make it way more difficult to find deals. 

If you're looking for the all-in-one I'd go with a PM software (others have suggested some) and do what you can with it.Then, as you grow further, look at more sophisticated/expensive options.

That would be my suggestion.

I'll definitely check out Set For Life by Scott Trench and The Total Money Makeover by Dave Ramsey for more financial insights.Watching BiggerPockets podcasts and networking with local investors are great suggestions.

Thank you for taking the time to make these suggestions! 

Prosper averages a 3-4% default rate (I would suggest 5% to be conservative).I have been investing with Prosper since 2007 and their loans absolutely default.

.: The reason that i would never suggest a single OTA is the all eggs in one basket risk.
