Moderator), go for bank financing first (even though it provides the most hassle) and then go for more of a portfolio lender once you've either exhausted that avenue or you don't qualify.There is a lot of good information about structure and how it affects purchases and lending here on Biggerpockets with a wealth of relatively free information. 

You mean in the event that you would need to sell one of your rentals suddenly you want to make sure it can withstand a downturn?

On the weekends, when I was exhausted, they were running around dealing with tenant issues. 

@Mike Stevens there are limitations, here are a couple (but not exhaustive):1.

O’Neal’s business assets have already been seized, and his personal assets may be difficult to find, if they haven’t already been exhausted.

I was paying $150 for 18x24 with stands. (100) I did a few searches, but the prices seem high.

If you can't withstand a 10% reduction in anything you are treading on some seriously thin ice.

I would be interested in their cost. 80% is good, but 92% will allow you to use the panels a bit longer than 25 years (if the actual roof will withstand).

I'd like to exhaust my options locally like how someone mentioned venturing out to further out suburbs and whatnot to see if I can find some deals out there.  

Boone says it best:Turnkey sellers deal with so many buyers so quickly that if they spent that much time answering exhaustive lists of questions from every client, they would never get anything done.This doesn’t mean that you can’t do your due diligence before investing.
