Defaulting on cheques for buying a rented property

Hi

I have a question.

My landlord, from who I’m renting, asked me if I was interested in buying his house in April this year. I got into a conversation with him and few months later we agreed on a price.

This price of the sale was including the remaining rent ( until November 2018 ), we agreed on not paying the rent until we signed the agreement as the rent was included.

I gave him a security deposit ( not to cash ) cheque. Now, my situation totally changed and I nodded the money also. I recently had a health issue that was preventing me from buying the house.

So the landlord called off the deal and said I defaulted on the deal.

Anyway, he now cashed both the rent cheques and the security deposit and said he went to the police and I will go to jail within the next 24 hours. Please advise.

I’m willing to pay the remaining rent but need time to get the funds ( at least a week ) and also I’m worried about the security deposit of the sale as he deposited this cheque as well, 3 bounced cheques!
