For example, say I have a foreclosure, or expired listing lead that I would like to find accurate phone numbers for for prospecting.

Why not have an online meetup in the second week of April?

Any leads are appreciated.

The counties themselves take 2-4 weeks to record a document online.

Go to courthouse in city where your rental is, or see if docket is available online, and write down the names of the attorneys with the most landlord-tenant cases.

I just stumbled upon it online and I’m trying to research it myself. 

My humble advice to anyone attempting to do creative finance is:Creative finance is for experienced investors who have access to capital if anything goes wrong.Learn the lawsDon't use a contract "off the internet", laws vary by state and are also regulated on a federal levelLearn the financing techniques correctlyDon’t skip parts of the processDon’t ever do a “kitchen table” closingUse the proper deedAn attorney can help you with the legal work, but the rest you are on your ownYour guru will not bail you out“Investing” in someone else’s deal by providing a small 2nd loan so the “investor” can pay for “cash to the seller” and for “closing costs” so he can do the deal is a very bad planKnow what problems can ariseLearn the responses and solutions to problems before they are neededKnow everything there is to know about Title and what that meansKnow who a "protected class" individual isLearn the "back doors"Learn human natureUnderstand timelinesUnderstand regulation enforcement (some of these "mistakes" have a 10 year statue of limitations ( they can charge you 10 years AFTER you do the transaction) and carry hefty fines and possible imprisonmentThe court doesn't accept "I didn't know" for an answer"Know that the source of the lead plays a serious role in some states and federallyKnow how much of a "profit" pushes the boundaries to invite an investigationYou can be sued by the seller if you don’t do things correctlyYou are automatically at fault if an investigator or attorney or regulator gets involved.

My recommendation would be to get approved as a Landlord, contact the director's office and request that an inspection be completed before a tenant is selected (sometimes they will do this as long as you select a tenant within 14 days - which you want anyways), and have an online application and screening resource in place.  

The second you are introducing metrics to change your marketing that have nothing to do with generating the leads you need, you introduce uncertainty to your systems. 

Or when syndication is struggling like it is move into the training business.there is huge money leveraging your on line popularity where folks will have an irrational opinion of someones bona fides based on SM media presence etc.
