Checkout Seth Williams (not letting me tag him) on this site and his own site, he has some youtub videos showing exactly how to do this. 

Of course the pickings have been slim to find a move in ready or light rehab MFR under 120kzHowever, I have found some and placed bids on a total of 5 since December 2016 when I was approved.. my challenge I want to know how to over come is getting my offer accepted when multiple offers have been submitted?

Any contractor worth their salt won't hesitate to submit a detailed line item bid on any work that needs to be done.

Take pictures/videos now to show what happened..

We have not submitted the offer yet.

I'm in uncharted waters here, because these girls don't have any of the normal IDs or means of submitting them to collections.

If you feel that you're analysis is correct and you have done you're research submit your 75% of asking price offer and give reason to it. 

Since reading, watching the youtube videos, attending a free webinar, listening to the podcast, I've decided I want to get into real estate investing!  

You submit an offer to them.
