This deposit will let you know if buyer is serious about buying.

We offered for him to break the lease if he lost his deposit and paid a penalty of one months rent.

Most banks have it, it's instantaneous and free, with a text alert on deposits.

I deposit my paychecks there and for all the time the money would usually sit idle until the bills are paid, the heloc interest calculates daily, so it would be lowered by my deposited income.

Also make sure the current owner gives you the tenant's deposit as you will need to return it in full when the tenant leaves (because you don't know the condition of the home when they moved in) as well as prorated rent.

Total checkable deposits for the bottom 50 remains high.

I recently attended a probate sale and it required 10% offer price of deposit to be elligible to attend the bid.

As a different example altogether, when I rehab a property, I deposit the budgeted money into a separate bank account and all expenses for that rehab are paid out of that account.

I also know that doing a 1031 exchange will enable us to carry all of the proceeds from the sale as a deposit on a new property.   

Did you have a deposit when u bought the property?
