We stood in like for over 4 hours today and finally got to speak with someone in person. Here's what they told us. Hopefully it helps your claim

1. FEMA will only help with repair costs of 1 vehicle per household, ONLY if all vehicles are undriveable and you didn't have comprehensive insurance.
2. If you're in a roommate situation, you should both file individual claims
3. Get a letter from a mechanic stating your car is damaged beyond repair, you can also go to the title agency and request something from them.
4. If your renters insurance is doing an inspection, push them to do it sooner rather than later
5. Provide lease and bill showing you live in the place you stated in your claim
6. If you have already removed damaged property, write and upload a letter stating that it was removed due to health and safety concerns.
7. Take and keep pictures of the damaged property
8. Create and upload a detailed list of the damaged property that lists: property type, original value, current value (prior to flooding)
9. Damaged property that was in a garage or shed will not be covered, however if your insurance denied all coverage, they can help.
10. Upload coverage denial letters

I think that's about it.

Update:

If you uploaded a license, passport, or something else to identify you, it gets dark on their end, brighten the images a little before uploading them to prevent being denied due to a dark image. We had to redo that as well while we were there.
