Oddly, Vrbo bookings nearly dried up and I get a steady stream of Airbnb leads despite the higher rate I set there.Unfortunately, by giving Vrbo a three-month exclusive head start, I missed revenue that could have been earned by listing on multiple OTAs from the onset.

I recommend searching "arbitrage" here and reading any/all of the hundreds of general threads about negative elements of arbitrage.

Well even if the rent is equal to the mortgage, you'll still be in the negative after repairs, CapEx, vacancy, etc.Why would you specifically be thinking of investing at a negative cash flow?

My team lead is a mentor of mine so to speak but in general, the people i have met through REI meet ups have considerably changed my trajectory and are real world, local examples that have helped me along the way and for free.

Curious as to whether anyone uses them and has anything negative to say.

In the example you outlined and in the case of what a lot of people are doing right now (super high LTV underlying, negative equity on wrap, 100% financing for the buyer, low note rate, etc), then no, this wont work, primarily because whomever created the wrap note is either an idiot or a fraud.  

Significant and sustained population growth leads to demand exceeding current supply, causing prices to rise until there's a rough balance between sellers and buyers.

This stark contrast leads me to question the legitimacy of the program and its purported benefits.In conclusion, my experience with James' mentorship program, particularly through the actions of Kristin Witherspoon, has left me disillusioned and skeptical.

Not all inquiries are good leads.

Also, focus on 2 years of job/income stability.Class D Properties:Cashflow vs Appreciation: Typically, all cashflow with little, maybe even negative, relative rent & value appreciationVacancy Est: 20%+ should be used to cover nonpayment, evictions & damages.Tenant Pool: majority will have FICO scores under 560 (almost 30% probability of default), little to no good tradelines, lots of collections & chargeoffs, recent evictions.
