Your first step is to set a budget, identify your saved up capital (deposit and closing cost plus the amount of money that you can afford to borrow. Your Jamaica National Building Society credit officer will be able to give you a good estimate of this.
Examine the mortgage arrangements that would best suit you. Get prequalified for a mortgage; this will significantly strengthen your offer when you find the perfect home.
Get details of all expenses associated with home purchase. These include (stamp duty, legal fees, application fee, cost for surveyor's Identification report and a number of other lesser charges).
When you have found that perfect home, your GM Realty agent will assist you with makeing an offer and negotiate the best possible price, this might include counter offers and more offers!
There will be a lot of back and forth between you, your GM Realty Agent, your Lawyer, the Vendors Lawyer, your Mortgage institution and the Vendor. All of which should be kept to a minimal.
You should do a final walk through of the house armed with you Surveyors report, your Engineer report and your pest control report etc!
