<prompt> Human: Heres a little backstory:We moved in to our apartment in September 2015. The ad showed the apartment as 825 rent with 700 deposit. The rate and deposit are ok for the area so we accepted and moved in. The landlord is a brand new owner and first time landlord. The apartment complex has 4 apartments total. Once we met our neighbors, we found out they were paying 600, grandfathered in from the previous landlord. Thats fine, we though. After all, that rate was probably from years ago. Jump to this month. One of our neighbors moved out and we noticed the For Rent sign. Out of curiosity, I had a friend ask the landlord how much the place is going for and he was told the rent is 725 and deposit is 500. We were floored. The apartment is the same size as ours and the amenities are no different. What can we do in this situation? If it matters which Im sure it does, the only thing signed was the deposit payment date agreement. I never signed a contract of any kind.Edit: Thank you all very much for all your advice and suggestions. To clarify a few things:1. Both my unit and the empty unit have the same exact floor plan and size, the only difference being that its a mirror layout of mine. Both units also face the street, not the parking lot. The only real difference I can see is that my kitchen and dining area get sunlight all day whereas that unit doesnt. 2. I did not sign any kind of contract. The only thing I signed was the agreement that I would pay the second half of the deposit once he gave me the keys on the Sunday that I moved in. When we both arrived, I gave him the money, he gave me the keys, and left. Since then, Ive only seen him two other times on occasion. The deposit agreement was a 3-sentence document stating the amount, date, and our names. Nothing further. 3. The whole supply and demand thing makes absolute sense. Quite a few apartments have opened up in my little neighborhood and theyre all priced between 700-800. Im sure the landlord is really just trying to get that unit rented out ASAP since its been sitting there for about two months.  <response>: Nothing. You accepted the offer as it was.
