If the security deposit is not enough to cover lost rent, utilities, and damage, you are welcome to sue in small claims court (which most of us have never done).

I have bought notes based on bank saving time legal fees and property damage during the foreclosure process, if you were buying residential paper I would look at the foreclosure timing first if it is like Wisconsin you can get the banks attention if it a very fast moving process like I am told florida is note purchass can be difficult

Worried about no pays or damage?  

I imagine it's higher than a typical single family rental considering it looks like the host usually ends up paying for any damage caused by tenants due to a variety of reasons (tenant refuses to pay, damage happened in a common area and it's not clear what tenant caused it, etc.).- Rental loss - PadSplit claims they collect 97% of rents, but I've spoken to a few hosts who have said that a much larger % of their tenants get kicked out owing $500 or more in back rent that is rarely ever collected - what's your experience been here?

.- increase in vacancy to 30%, 40%, 50% (this could be a combination of bad luck: one unit water damaged, one unit tenant trashed, and you have to evict two more - on a 10 unit portfolio that would be tough, even though only temporary)- lower rents (for whatever reason, what happens if rents go down 10% or 20%?)

No, it's not touching a nerve!

I have yet to see code violations, water shut offs, and fire damaged properties. 

Those nerves should be gone, but they are not.

Since most of the homes that flooded took on electrical damage, you will almost certainly need to file a permit to do renovation as you will need the electric company to shut the power off, provide temporary meters, and turn the power back on.

Not enough damage to make it worth it to pursue them, but the trail camera worked as intended
