I let a husband and wife (she's an acquaintance of mine) move into a SFH without paying the deposit.

Slim to none on that anyway.Personally I have lost a lot of money on land deposits and unfortunately so will my investors.

My estimated rent range was $850 but it was rented out for $950 with an $800 deposit.

My hope would be you have some sort of deposit to help cover costs.

We didn't renew his lease, but offered him $250 and his full deposit if he moves out 15 days early.

I will have security deposit check in hand, do the walk through when you hand me the keys, and I will hand you the check.

Buyer will put down 10% deposit.

I wonder who's going to pay the advertising, office supplies, management, maintenance, entity maintenance, damage done by tenants (above the security deposit), legal fees, utilities (during vacancies), evictions, vacancy expenses, lawsuits, capital expenses, etc, etc, etc (I could go on and on and on).

I guess I did have one tenant that didn't pay their final water bill, but I deducted that from their security deposit.

You might have to pay part of their moving costs or deposits on a new place to live.
