The OP would have to let us know if she worked through one of them though.The larger are well known TK resellers/marketing companies are:RTRHartmanreal wealthMaverickNorada Most of them also do other things than TK  and some of them are also principals in the transactions not just marketers. 

Our experience is Airbnb, 60% of bookings, Zillow, 30%, Furnished Finder, 1 booking.

What is inside the book of Norada really ?

You should start getting bookings almost immediately. 

Buy a few books, start simple, do your own property managing.

I joined after reading 5-6 of the BP authored books and I've loved growing my understanding of the world of real estate investing.I made my first investment this summer and my family is partnering to make a few investments in the next year.

The other book you mentioned caters more to that audience and gets people hooked on the idea that they can invest in real estate with no money and then teaches them how in subsequent books. 

Both great books.

So I will speak to you know, mask off in a raw and unfiltered way and tell you what has happened to me in the last few months, this I believe is one for the books on real estate horror stories as I have lost all of my money and nearly lost my life. 

I have been doing this since the mid 80s  over 3500.00 transactions and If I can do it you can do it :)
