I figured there should be more than one way I can monetize that list.

And I suppose that is exactly what you are doing now monetizing Biggerpockets, as a digital recurring income platform.

I'm generating more leads than I can use and am looking to monetize them.Does anyone know of any platforms or marketplaces where such leads can be sold directly to listing agents?  

. $2,000/mo net cashflow. 

When any little hiccup comes along that most of us did not financially prepare for we Demand the GuvMint do something, like my stock portfolio dropped 25% today in 10/87, so drop interest rate to Zero, thanks Maestro Greenspan, or again in 3/2000 when Yahoo.com didn't somehow grow into its projected 30 trillion dollar market cap based on its PE of 700, drop rates to Zero and keep 'em there for 22 years except for brief interludes of sanity (inflation got above 2%), or in 2008 when no one with a pension fund in America took any damn responsibility/oversight and gave their retirement funds to crooks to buy whatever ratings agency rubber stamped dogshit inverse synthetic CDO they could get a commission on, then were shocked, laying on their fainting couch clutching their pearls when the financial system reliably imploded, so drop rates to Zero again and start Monetizing/printing the debt, and now with the most predicted pandemic in history, Americans hadn't saved a damn cent so we cried to the GuvMint, send us 7 Trillion dollars now, I need a new Lambo!

I'm not monetizing this in any way, and I only have a limited amount of time I can devote to this project, so I won't be able to review every one of the dozens of different products on the market.What's next is probably a review of REI Hub, which is likely to be the product I settle on based on my initial experiences with them.

.$275/mo net isn't too bad...If you really think that it will appreciate, then it is worth it rent out. 

So now I'm vetting STR PM companies in order to monetize this consistent opportunity. 

Does anyone have experience with the Monetized Installment Sale approach?

I would love to touch base with someone on strategies on how to monetize these leads.
