Lease tricks

Today, two of us received communication falsely stating that we did not submit a signed copy of our lease renewals. We had both already received it back with the landlords usual scribbled signature. My security deposit check, submitted with my signed lease copy had been cashed in January.

What trick could this be? They consistently use certified letters, whether actually mailed or not, as verifiable evidence. The sad truth is that city/state agencies accept just a copy of a letter and (even unstamped) certified mail receipts and landlord’s word as proof of whatever they claim. Tenants factual evidence and testimony is always disregarded. Hmmm….Do I wait to see how they use this certified letter, or ….??
