Investment returns automatically deposited on a regular basis.

Large deposits are nice, but very difficult to actually get access to escrow funds in the event of default.

Quote from @Havital Miltz: I think it will be very difficult to show 750 hours, most tenants deposit the rent, so there is no rent collection. unless you have a very high turnover of tenants, where  you need to show the houses again and again,  I am not sure where you can "find" all those hours for her, especially that you say the properties are newer, so how much repairs would you have?

If it's not a holiday, I would say, "No, the deposit remains in place until your lease ends."

Did you collect a pet deposit?

We have some $ saved  but don’t have enough to put a full 20% deposit down as needed by most conventional lenders.

A good property manager can help with tenant screening, enforce lease terms, and handle evictions more efficiently if it comes to that.Require a Larger Security Deposit: Within the bounds of local regulations, a larger deposit can provide a cushion in case of damage or unpaid rent.Consider Rent Guarantee Insurance: Some companies offer insurance products that can cover lost rent in case of tenant default.

Give her 30 days notice now, keep her security deposit, and send her a additional bill for damages to the unit in lieu of taking her to court for the damages.  

Follow the step for the deposit-even if it is to send a registered letter to their last known address stating that the deposit was used for outstanding rent and whatever damages or cleaning was needed (itemize it). 

Nomad also held the renter's deposit hostage even after I cleared the transfer with no damages to be charged.I had to remind Nomad there is a difference between “can” and should” , while you “can” hold a deposit longer it “should” only be done when there is a question about damages.My bank liked the guarantee, the disorganization inside Nomad and the horrible vendor management would cause me not to use them again.
