LLCs can be a lawsuit deterrent but only because of ignorance of the law.

Maybe I'll drive by the property so I can pretend it's mine and visualize my goal!

When times are tough, getting good tenants can be challenging for them and me, so an application fee is see (by me) as a deterrent. 

@Phil Hong If you're just wanting to look at a map then http://graphics.latimes.com/soft-story-apartments-needing-retrofit/ is good because it's visuall mapped out, though i don't know if this is a comprehensive.

Depends on how much sheetrock repair and touch up they had to do....not enough detail on what was actually done.You may have been screwed out of a couple of hundred bucks at most.... price doesn't seem too off to me for what I would visualize in my mind as being done.Best you can do is next time get better info on what the actual issue is.....condition of the actual damage...... get pix before, during and after...more detailed invoice.I probably wouldnt sweat this one....but make the plan on how you handle repairs and quotes in the future....

We got HELOC without visual appraisal ,$0 closing costs .

Establish a monetary fine via your rental agreement as a deterrent to tenants allowing others to move-in without your permission.

We also found a duplex with a top floor partially renovated and move in ready, that contained a downstairs unit that needs a full cosmetic touch up, but should be move in ready in maybe 2 weeks time.I intend to visually inspect the neighborhoods and do several walkthroughs with an agent while down there next week.

If you want to figure something out when it comes to repair, it's the first place I turn to, to see if there's an visual content on what I'm trying to achieve. 

I take a map and highlight the streets as I go (red = "A" neighborhood, blue = "B", etc.) just based on my visual.
