Most auction companies if the house is occuppied will tell you your not allowed to approach the homeowner.I violate this everytime.. set max bid and semi stick with it though.. but one trick is its human nature to stop at round numbers IE I will bid to 205k and thats it..

It would not take much of an innocent human error (overlooking some roffing/plumbing/electric problem) to eat that up quick.Taking appreciation out of the equation (cause that is educated speculatiin and I do not know your market), I dont thinking tying up the down payment is worth it.

Or better yet, also search names and message body too?

There will be time for you to make a reasoned judgment about this later.I know what a decent human being feels upon receiving an inheritance, however small or large.

Don't use excel to manage all leads. it's possible, yes. but you're going to run into issues and ain't no body got time for issues!

As the others here mentioned before, it's critical to check with the local planning commission and city/county governing bodies.  

But the weird thing is no body knows who pays taxes, even on record the seller said; "yeah I was confused about that for the past 10-15 years"

This is typically the case here in the Bay Area, too.Typing Alexandria Louisiana in the body of a post so that locals to OP, hopefully, can chime in and tell us how it is in LA.

Then I have to go to the Secretary of State website to enter the entity name and see if I can find the name of the actual owner (human) who owns the LLC and then cross-check the mailing address provided by the Title Search report to see if it's a residence and if it's the residency of this person.It's not only highly inefficient and not scalable but also highly inaccurate. 

Realize, too, that fix and flippers tend to have cheap sources for this sort of thing and would not pay anywhere near what a homeowner would pay a kitchen fixing company.Your best bet may be to donate the cabinets and appliances to Habitat for Humanity.
