It depends on where you saw the advertisement (MLS, Newspaper, Craig's List, Westside Rentals, etc.) In the local MLS, there are 3 types of cost: 1st type of "cost" is the "Move-In Cost" which usually includes the 1st month's rent and the security deposit and pet deposit (if pets are allowed); the 2nd type of cost is the regular monthly cost, which is your monthly rent and any other expenses that the landlord ask you to pay such as HOA dues. The lastly and 3rd type of cost are utility bills; while most landlords pay the water bill, some do not; so you may have to pay monthly utilities costs such as water, electric, phone, cable, etc. Make sure to ask the landlord exactly what you (the tenant is responsible for) and what the landlord will pay. Make sure it is fully documented in the lease.
As a side matter, if you are willing to pay $4,250 each month for a town-home, you may want to consider purchasing as you can own a great single family home or townhome with a monthly mortgage less than $4,250 per month and still get the $7,500 tax rebate promised through the new Housing Bill if you are a first time home buyer.
