WHAT MAKES UP A MORTGAGE RATE?
Most mainstream rate quotes would be structured as a 30yr fixed from a big bank or mortgage lender, a retail branch of that bank, or indirectly via a mortgage originator who has access to several correspondent or brokered banking channels. In all cases we’re talking about some large underlying financial entity that is in the business of making lots of loans.
These sorts of lenders will typically adjust their rate sheet offerings every day. In fact, it’s extremely rare to see absolutely no change in any given lender’s rate sheet from one day to the next. That said, it’s also rare for rates to change so much that the actual contract interest rate is affected. That’s because rates are almost universally quoted in .125% increments. As such, rates would have to change by .125% in order for a rate that had been quoted at 4.0% to now be quoted at 4.125%, all other things being equal.
The “fine-tuning adjustment” for mortgage rates lies in the upfront cost side of the equation. This can either be an actual cost out of the borrower’s pocket (“discount points”) or a rebate from the lender. Rebates to cover closing costs, etc., are a common feature of loan quotes, and lenders are able to offer them because of the interest collected over time. The higher the rate, the higher the potential rebate. The lower the rate, the higher the cost. For example, if a 4% rate involved neither an upfront discount nor a rebate from the lender, then a 3.875% might require a 1.0% discount point and a 4.125% might result in a 1% rebate from the lender.
Comparing mortgage rate quotes is more in depth than just the program, term, and rate as the cost for that rate (or rebate) is a significant factor to make sure you are getting the best loan for your unique scenario.
