My question involves landlord-tenant law in the State of: Pennsylvania. I answered Craigslist ad for an apartment for rent for 560 a month utilities included. In my lease it states that if I pay the rent before the due date on the 1st of the month I can deduct 40 Dollars from the rent making at 520. When I did so and paid 520 for the month's rent my landlord contacted me and said I was 40 short. I then notify him of the cause in the lease stating my deduction of 40 dol. For prompt early payment. They then said that the rent is 600 with a 40 dol. Deduction making the rent 560, But on my rental lease it states that my rent is 560 per month not 600 and it was advertised at 560 not 600 and 560 with the early pay discount. The figure of 600 per month of rent never came up in the ad verbally or in the lease.can they change the lease to read 600 per month rent when it originally States 560 per month rent without my consent or signature of the lease and can I go by the original lease and not pay the 600 per month rent. and also take my 40 discount if I pay before the due date and not be in breach of the contract or would they be in breach of the contract. thank you in advance for all of your help any answers greatly appreciated. sorry for the grammar spelling and punctuation but I am using voice text through my phone I'm sure you know how that works. thanks again
