If you are ever forced to sell, or you end up with toxic tenants you might be finished.

It is often too difficult emotionally or mentally exhausting to give up their previous home.

@Daniel Solano WolfeI grew up north of San Francisco and decided to live and invest in Reno, NV. 

Are there any resources for learning how to set up systems?

As long as it makes sense that you are "moving up" it's good.

You open yourself up to some major trouble if you don't.Example 1: 26-year-old female applies.

Most 100% lenders will lend at 100% UP TO 70% ARV, which is tough to secure.

I am planning to move into the home for at least a year once the existing tenant's lease is up in a month, and I intend to keep it as a rental for the foreseeable future.

Is there a reason such as an incomplete address history or settling in court that these cases would not have come up on the report?

The worst ones usually don't have any clear cut guidelines (a lot of the underwriters will make up their own rules if they do not like the deal), Suck at communicating (will reply days later), Push aggressive terms to get deals in and then switch them, and Not really motivated to get things done (they will adverse a loan without any hesitation).
