And sometimes you are blocked because the wall you need to put it on has a window.    

I'd plan to manage it myself, as I know it very well and it's a few blocks away.

But if it looked like my calendar could do a turn on one of those days, I would ask my cleaner if they would be willing to do it for the extra pay or block that day.

Make sure you know the safety and quality of the neighborhood and even block in New Orleans to ensure the rents will be what you expect. 

I have resorted to FB with a biz profile and have blocked her profile so we will see what happens although I haven't had any luck with FB before.

After 2 messages, BP started blocking me for "spamming", so .

But even if crime mapping is unavailable I would recommend calling or visiting the local police department and having a talk with them about the safety of the neighborhood/block. 

It involves ground work, gravel, possibly concrete pads or blocks.

And assume everything is a little worse than it looks given the tenant's stuff is probably blocking some problems and things like the carpet and paint will likely look worse when they move out.Lastly, is it necessary to go over asking?

Then, think of only buying houses etc. in the fire zones that are made out of concrete and steel and cinder blocks, without asphalt or wooden shingles.
