Making an offer involves a lot of strategy. You don’t want to turn of the seller by low-balling him, and at the same time you don’t want to pay too much for the property. Your real estate agent should be involved in brokering the offer, as they can advise you on a realistic offer that maximizes your chances of buying that property. The seller will most likely have their own real estate agent, and they will want to maximize the sale price. So don’t get into any negotiations with that agent without the presence of your own agent.
DO NOT make decisions that affect your mortgage payments by making any other major purchases and don’t switch jobs. This is just added hassle that will prolong the process. Also be sure to obtain hazard insurance, and switch utility providers, and don’t forget to cancel any services in your name at your old home!
