Leo rents an apartment from Donna for 900 per month, both parties signing a lease. After six months, Leo complains about defects, including bugs, inadequate heat, and window leaks. He asks Donna to fix the problems, but she responds that the heat is fine and that Leo caused the insects and leaks. Leo begins to send in only 700 for the monthly rent. Donna repeatedly phones Leo, asking for the remaining rent. When he refuses to pay, she waits until he leaves for the day, then has a moving company place his belongings in storage. She changes the locks, making it impossible for him to re-enter. Leo sues. What is the likely outcome?
