After searching more, I found a few BP post where people seemed to have one account for all deposits, and keep only deposits in there.

I avoid cash as it is a safety risk to have large amounts on hand.

Hey @Thanh Lu, we don't do much direct bookings but we do have a $500 security deposit.

The underwriters will be looking at similar property condition requirements (c4 or higher) of a conventional loan (no deferred maintenance or safety hazards which would affect value).  

WOW.. 40k plus deposits on a home to be built.. ??? 

You’re not using a PM, AND you’re assuming you can charge a service animal a deposit and pet rent?

We also received a $2400 security deposit.

  $2500 deposit is put down. 

The law does NOT apply to landlords:With less then 5 rental unitsThat live in one unit of a duplex and rent out the other unitThat rent out rooms in the home they occupySo, landlords can no longer state in their rental ads, "Section 8 not accepted".The reverse is also true, "Section 8 only", cannot be used.We've always recommended screening S8 tenants the same way as cash-paying tenants.Landlords waiving application fees and/or security deposits only for S8 prospects may also be violating Fair Housing.

It seems like location would be especially critical with pad-split (and similar systems), but I’d love to hear your thoughts on what to watch out for in terms of zoning, safety, or demand.Also, I’ve traditionally rented out units the regular way, so I’m curious how screening tenants works for you with the pad-split (and similar) model.
