I was going to offer to have the testing done but tell the tenant that if the results show no harmful mold, the cost would come out of her security deposit.

There will be a rise of flat fee brokerages (offering limited services) and creative compensation arrangements, such as RE consultants for time or a specific transaction.

I usually just look up the real owner in public records, skip-trace their contact info, let them know someone is trying to use their land for a scam and offer to put a sign up at the property that says "NOT FOR SALE" (ironic for a real estate agent right?).

NAR has offered to settle.

Make an offer based on you terms!

Adam,Just to clarify I think your post was good to establish the changes coming and it does help to offer insight. 

I have thought of offering them cash for keys, just unsure how that process would work.

I planned to assign this property initially for $115,000, but had a major reality check after talking with a lot of local buyers and was lucky to find one who paid higher than my offer price.

Networking through local real estate investment groups or online forums can help you connect with experienced folks who can offer guidance, but also do your own research on the way.

This actually makes it even easier for an agent because they don't have to drive around looking at 10 houses before their client makes an offer on one.Without BiggerPockets, it would be extremely difficult to find an investor-friendly agent because it was hard in 2010, and today not much has changed.
