Residential Lease Termination

I entered a residential lease agreement for two years, but released after one year. I received two months' notice before leaving in accordance with the agreement. Its been over 4 months now and the owner has not reimbursed the amount of rent.

Can I request the interest of the owner, even if in agreement, he said he would not pay if interest payments are falling behind?

Yes certainly the owner obligated to pay interest on the amount of rent until he pays.

even if in agreement, he said he would not pay interest if the payments are delayed, this does not mean he can keep forever. a reasonable period of one month can be accepted without interest. when four months already elapsed, it must pay interest.

Edit:

From your previous question, I think you have not given the keys. How can you expect to pay interest?

my answer before changing online is only valid if you had returned the keys 4 months ago. when you hold the keys, he rises to keep in your possession, you are not entitled to interest.

If you have given your two months' notice that you're entitled to your security deposit plus accrued interest. Then, less the costs or damages claimed by the landlord. must submit a detailed list of all the costs he refuses. Your landlord must have had your security interest earning account. The rate of these accounts is usually very low, not worth fighting for. But your landlord must return your deposit within 30 days. He can not deliberately withhold

In the rental amount you mean deposit.
You must have requested a check for that amount that you received vacant possession.
How did you accept these terms in the Agreement?

You can ask anything you want ... this does not mean the owner is required to pay.
