Mariya, The answer is No. Landlords these days are pricing these properties based on a 12 month lease. Typically, they will not discount the lease even if you go longer than 12 months. However, if the property stays on the market for a while, they may be willing to consider a lower rental rate. This property has been on the market for 28 days. Given that it has leased for $815 in the past, the landlord might consider something less than $850 based on the quality of the tenant profile (rental history, employment history, proof of income and clean credit/background).
You should have a Realtor to assist you with any lease application and negotiation so that you are protected. It doesn't cost you anything. Let me know if you need help.
