This is not going to explode your money but CDs provide a guaranteed return. 

Is there someone in the chain of document recording that is guaranteed to see a ROFR associated with a title?

Most banks will probably need you to personally guarantee the loan, which will keep your personal finances entangled with the flips.

(Tenant exaggerating by saying 3rd time)Pennsylvania Supreme Court has ensured that Tenants have the Right to a decent place to liveThis guarantee to decent rental housing is called the Implied Warranty of Habitability.The Tenant is also Protected against Discrimination & Acts of retaliation for reporting Repairs /ViolationsYour Contractor suggested Repairing & Remediating Mold Concern Saturday 6th July this date will not work .NOTE: No commitment to make any repairs received by the Landlord (HE IS LYING) Today ABC CO.

By way of clarification you don’t have to wait until you ETS to obtain a VA Guarantee either.

That being said, the preferred return isn't guaranteed, so what makes the most sense is the sense you make of the sponsor. 

The kids will do damage to the property, that's almost 100% guaranteed.

Anyway, all else equal, you can’t guarantee that anyone who shows you the house while working for the seller would not disclose your info like you’re really interested (and more likely to accept a higher price).

Applying for a variance doesn't guarantee success, so that $15k could be a total loss if the request is outside of the neighborhood's zoning and current activity- ie: denial.

Of course, there are no absolute guarantees of a quick sale.
