They need to get in there to check the moisture in the walls right now.  

You just stated for the 2nd or 3rd time now that their negligence caused the excessive damage to the floor. 

.- Excessive mice droppings along walls.- I was told they found a mouse in the couch.- They have put traps out and caught some.- Young mother (mentally disabled and daughter of tenant who pays the rent) has an 8 month old.I went over and put multiple bait stations and traps on the advice of my pest control guy.

The advantage to this is that the fan can continue to run even after the tenant is out of the shower and continue to remove moisture from the room.Anyway, that's just a few ideas.  

You may wish to confirm that the new 401k provider will handle the ongoing compliance support such as any required 5500 filing (e.g. 5500-ez for a one-participant plan with assets in excess of $250,000), any required tax reporting (e.g. 1099-r in the event of a distribution or in-plan Roth conversion), mandatory plan updates and amendments, etc.4.

They can then produce reports per customer.Every month, they would settle with customers, either sending them the excess cash flow or receiving money if shortage.Model your setup after this, and you should be fine.

The subfloors are typically a composite material and any leaks or moisture inside can rot them quickly and they crumble.

I use maintenance/cap ex numbers that many would find excessively high (but I believe are not that conservative). 

The property cash flows great and it's value is in excess of $425k.

Fire loss was in excess of 140K.
