It looks like most of the options here (cozy/transunion/experien) recommend the tenant fulfilled screening versions which work great for one or two screens a year.  

., but if I understood your previous post, you were suggesting someone take a holding deposit FEE, that could only be converted to a security deposit if/when the tenant moved into the property AND FULFILLED THE CONTRACT THEY WILLFULLY ENTERED INTO.

With that said, if the owner released your friends from the lease contract then they are no longer obligated to fulfill the contract.

This is the problem with trying to fulfill your due diligence while a tenant is in place...

Did they fulfill the lease term?

I would add that you should find an attorney for your team to review your contracts sooner than later in your investing career, and they may be able to further explain the ramifications of a tenant not fulfilling their end of the rental agreement.

M2M could mean the tenants have already lived there and fulfilled their lease.

I do something that some view as illegal, so I would advise anyone to view their local laws, customs, etc. i am a huge fan of "rewarding" the tenant for fulfilling their monthly obligation.

When you embark on you real estate empire building journey, you must ask yourself if your primary goal is to fix the societal problems you mentioned above, or if it is to make money.If your primary goal is to help others, you would be better off working with charities.  

So take a security deposit and treat it first and foremost like a rental which only upon satisfactory fulfillment of the lease are they elgible for a land contract.
