I'd buy a Tesla Model S 85D, a big bag of medicinal marijuana and flood Ben Leybovich email with great deals for him to lend on for me.

Use ACH for rent collection.

. - We helped the client with an action plan to streamline their process, put audit trail in place, create a workflow, implemented a procedure where each employee was delegated one step of the process (without the other person knowing that they were been internally audited), and customizing reports and in the end we were hired in being a part time CFO- They still accept cash, barter, money order, ACH, credit card no Bitcon yet.

Venmo is doing an ACH, most likely, so you would typically only have 60 days from the time it appeared on your statement to request a reversal through your bank as unauthorized so that won't be an option unfortunately.  

Make the seller's monthly payment directly to the lender (by check or ACH debit)?

From direct ACH, last place I thought of checking.I was suspicious though half way, but couldn't find any proof that I was charged $99 every month in his membership area, nor was there a cancel button, and there was barely any content in that area, so I thought I wasn't charged, further maybe I wasn't even a member, and stopped researching.
