Where does the rate spread go when you borrow in Slidell?
Banks often add margin between their wholesale cost and the retail rate they quote you. On a $400,000 loan, a 0.375% markup can mean about $1,500 a year in extra interest, which is why comparing offers matters whether you are buying in Lakeshore Estates or near Fremaux Town Center.

Across millions of purchase mortgages each year, retail markups can add up to billions in extra borrower cost. The wholesale channel has existed for decades, but many buyers in suburban markets like Slidell still never see the lower-priced options.
How does PierPoint remove the retail spread for Slidell buyers?
PierPoint gives you access to wholesale pricing, the same base rates lenders use before retail markups. PierPoint is paid by the lender that wins your loan, not by you, and your cost for rate shopping, underwriting support, and closing coordination is $0.
