Personally when buying rentals I tend to buy in neighborhoods that I feel like I wouldn't personally mind living in and when I look for tenants I try to look for people that not only pass my screening but also I personally don't dislike.  

No personal income or tax returns are required.

For mobile homes, it often depends on whether the property is considered real estate (attached to land) or personal property (if it’s not).

I personally like Alabama and Tennessee a lot, depending on what specific area you're looking at.Look for Class B or C properties in stable rental markets, particularly single-family homes or duplexes.

Pre-foreclosure - homeowners are desperate to avoid foreclosure and they quitclaim deed the title to some XYZ organization , person, or to a lawyer that specializes in foreclosure defense.

I purchase my personal investments to maximize their equity and hold long term.

Whether the seller was open to a buyer commission or not, I wouldn't put an additional cost into any personal purchase.  

They actually have a licensed person in California.

can anyone you know in person vouch for this lender? 

I can think of a few BP-specific cases where the ability to delete a post makes sense:Noobs don't usually get the '@' feature right the first time, so I am constantly seeing double-posts so that they can properly call out the person.
