It is advised to view the market of the area you are buying in for a while and see what the general prices of the houses are. This way you will know what a reasonable offer will be. The seller of the property will know what the local pricing is, so this could give you an edge over other potential buyers as you can give them the number they are looking for. It is advised that you have your finances in check before making an offer to the seller, to make sure they don’t take another offer. This is why you should sell first or go to the bank and query how much they can offer you on a mortgage.
