Much of the Tenant-Buyer pre-screening can be farmed out to VAs who you pay to answer the phone (Google Voice, Vumber, etc.) that you set up to receive calls from your marketing. 

To start, pick up the phone a call your local banks.

There are legitimate transactional lender already out there just google it, there a few I'd shy away from due to lack of professionalism, but there's a few that are easy to Work with.

Not only does this create a less fearful first contact environment for the seller, it also helps you qualify them before getting on the phone and best of all allows you to capture their phone number even if they don't leave a message.Although not directly related to finding the deals, I would add that in any highly competitive area speed and personal touch can make a huge difference.

As far as the FSBO I subscribe to a service called beenverified . com to find current address, emails and phone numbers of people 

I am fortunate  enough to know several people that are professional investors and are willing to spend some time mentoring and giving me experienced advice.

If interested let's set up a phone call.Gary
