They are saving their cash for the next deposit/1st months rent.

That didn't work for me, and I reiterated 1st/last/deposit, no response.

Be it a secondary bank account with no card attached to it or a 6-month deposit. 

Tell the tenant to go after the previous owner for their deposit in small claims court. 

I put my money in the coin slot and at that exact moment my body went stiff as a rock due to the ear piercing screech that went across the coming from what looked like an air plane but it had no color just the shape kinda like an airplane shadow.

If you want to go ahead and start looking for a new place, we'll waive the penalties for breaking your lease with 30 days notice prior to the start of a rental period and refund your deposit if you leave the place clean and completely empty."

If a price is agreed to you enter into the purchase sale agreement and wire the earnest money deposit. 

I always get 1st months rent, last months rent and security deposit at lease signing.

They were evicted September 30th and owe more then what the security deposit covers.

Make sure your offer is clear that you can void the contract if you find something wrong, like low rent rates, condition of the property, or you just don't like the neighborhood.I know some investors will make an offer sight unseen with a huge earnest money deposit (e.g. $50,000) but make their offer contingent on an in-person walk-through within 72 hours or a review of the financials within seven days.
