l have been leasing a mechanic shop since 1994 with an option to buy from the owner. $350 per month out of the rent went towards the option fee. The agreement also stated that l did all the construction at the property to bring it to code which will be deducted from the purchase price. I had $50, 000 more left to finish paying for the entire property. The owner just died. The heirs do not want to honor my contract, hired and eviction attorney and have evicted me from my property. Can l file a mechanics lien against the property?
