They flat out lied about several issues, so I could tell those presenters weren't credible.   

These include falsely claiming to have closed dozens of deals when none were ever closed, illegal payment of undisclosed sales commissions to bundlers and independent contractors, advertising the funds as safe and appropriate to investors with obvious near-term needs for their capital, creating fund of funds en masse assembly line fashion with no corresponding SEC filings, unregistered brokers/financial advisors acting in that capacity absent licensure, having customers wire money claim the fund is fully subscribed and putting them into a high yield promissory note, accepting funds from unaccredited investors, misrepresentations about the debt put on the project, lies about experience level of the principals, omissions of material facts, and at least two straight up Ponzi schemes.While it's true that some legitimate operators are having issues in their portfolios, today's circumstances are a perfect example of the idiom, "you can only discover who is swimming naked when the tide goes out."

If so, it's probably just because the appraiser or assessor was wrong originally. 

We still own the condo, we just have tenants in there who are willing to pay the HOA fee and the increased taxes in order to access the slightly better school system up there.Bottom line, someone who just shows up alone and out of the blue, says they make 3x your rent, offer you nothing else when you explain the income verification problem, and object to a month-to-month rental contract or an increased security deposit, well, they're probably lying about how much money they make.

I sent it to him.Be careful with the lies you spread. 

But at the end of the day, the numbers don't lie.  

The tenant has been a problem from the beginning, such as behind in rent for a year, buys a brand-new Jeep, lies about ex-husbands job, child support, court cases, etc...Now, the house needs a new deck, so I went up to inspect it.

Data doesn't lie: articles can point you in a direction or another to focus on the indicators they choose, but you as investor need to analyze the data carefully. 

If they are going to lie about something like this that has no financial consequence for them they are going to lie about other things. 

Most people wont get to this step, and if they lie you can catch it during screen (which the tenant pays for)4.)
