Good morning Jainesh Patel,
The FHA program allows a Seller to pay up to 6% of the Purchaser's closing costs in a purchase transaction. So, yes, your Realtor can negotiate with the Seller to include closing costs in the Offering price you make on the home.
You will want to consult with your Mortgage Banker as to how much may be needed for the Seller's concession for closing costs in your area as closing costs vary widely from State to State, County to County, City to City.
