I'm snapping pictures and keeping the addresses registered on the app. 

Dave, Cannot address all your questions, however assume you are running a syndication?

I actually did an analysis of a specific address (my own in mid TN) being hit based on all historical tornado info for a graduate level risk assessment course.  

If not send me the address in private message, I can help

A lot of the issues which self-showing systems seem to address only surrounds vandalism (if at all) but, ironically that is the least of our worries considering that most require the applicant to submit a valid ID and payment information... but really someone wanting to 'willingly' vandalize or burglarize a unit would just bypass the whole thing and simply just break in. 

what is the address? 

id=8b0adb51996444d4879338b5529aa9cdSearch the address, identify the structure on the map, and if any part of it (even the tiniest corner or a deck) touches the blue shaded areas, it’s in a flood zone and requires insurance.You can also go to Msc.fema.gov, search the address there for info on the flood insurance rate map.

To address your S-Corp tax election on an LLC this is specific to the client situation hence entity structuring is never a one size fits all approach. 

You can search by name or address. 

- Some agents seem to only want to know the address of my property, how can that be?
