One of the headlines says that Pinnacle's books reveal that they raised 60 million dollars...

Wait till he figurs out what he got himself into.Watching their moves to combat the economy will reveal lots of little "sweet spots" to make some cake.

He will not reveal more details.

@Bradley Bogdan Good point but I'm going to reveal something about the MLS.

Evidence presented during trial revealed that from May 17, 2005, until February 21, 2008, twenty individuals, under the direction of Robert Brooks, participated in a mortgage fraud scheme where Brooks purchased properties at fair market value then resold at an artificially inflated price to straw purchasers.

Other studies reveal the number of people in the workforce is continuing to decline.

Using an online calculator will reveal that price to be way out of reach.Also, going to a lender will lead to a similar estimate unless OP seeks a mortgage pre-approval which could lead to a hard pull on her credit. 

But if you're just concerned about his honesty in general and/or that he may be taking shortcuts with the rehab on the one house you're buying from him, you should be having an inspection done that would reveal any issues as far as that goes.   

Give the new tenant a stern warning, reveal the lie in the application?  

The mgt company will find tenants, screen them, manage payments, work the past dues, provide routine maintenance inspection services that can reveal problems in the process of occurring, and give tenants the clear impression there is "a sheriff in town" rather than the impression of 16 years olds at home alone while their parents are on vacation.
