Your tenant is in default because: i) the tenant did not sign the agreement for the reduced rent and thus it is not an enforceable agreement; and ii) the tenant has failed to pay the rent prescribed by the signed lease in the amount of $1700. So, yes, you can recover the $250/month the tenant is not paying. Unfortunately, it's unlikely that a court would allow you to recover damages
for the delayed sale of the house and/or any distress. The tenant's default allows you not only to terminate the lease, but also to pursue the unpaid rent. If the tenant doesn't voluntarily pay the unpaid portion of the rent, then file a claim against the tenant..you can file this in small claims court without an attorney. Filing the suit will give you the collection options and leverage you need to collect the debt owed you. That's because once the suit is filed and a judgment awarded, you become a judgment creditor, and if he doesn’t then pay the judgment, you can have the sheriff serve a summons on him for a debtor examination. That forces him to meet you in court again and answer questions under oath about his assets. After that information is obtained, you have the power to garnish wages, attach bank accounts, have the sheriff seize other personal property, and/or place liens on any non-homestead
property he owns to satisfy the judgment. Thank you so much for allowing me to help you with your questions. I have done my best to provide information which fully addresses your question.
