As evidence, many point to a large discrepancy between NOD’s and trustee sales.

Not everyone has the ability to weather such a discrepancy.  

However, I found a few discrepancies with information on my and some of my friends' houses.

I just found it odd that new people are still calling me in July from my previous campaign that began at the end of May.Is there a reasonable explanation on the discrepancy?

I would ask to speak to their ins. agent.When you find a discrepancy during the option period you can then renegotiate the terms of the contract. 

Until the appraisal happens, we won't know if there's a discrepancy or not.

I recall trying to use the work number one time and it was taking too long, so I used other routes to verify employment and income to my satisfaction.If you are suspicious about the validity of the pay stubs and/or think you found a discrepancy, talk with the prospective renter about your concern and see what she says.

They will probably also be messier and cause more damage.From a manager's perspective, I'd choose the newlyweds hands-down, especially if you want to manage it yourself from out-of-state.I don't know how to discuss the discrepancy in amounts of rent without more info on that.  

I worked at a Large over 300 unit complex. the prior manager had embezzled and I discovered this to the tune of about 60 K discrepancy.  

I would definitely get your own professional maintenance and just have full market rate tenants to offset.There's no telling what her level of true "maintenance" is that will cost you more in the long run from hidden issues than you'll save via a rent arrangement.And out of principle alone, she will give you issues over this $100 discrepancy and has the power to cause you problems (neglect, bad mouthing to other tenants, etc).Goodbye to her IMO!
