Stocks around the globe are in rally mode after recent polling shows Brits are in favor of staying in the European Union. The so-called "Brexit" vote is this Thursday.
When Stocks rally, this typically has a negative impact on Mortgage Backed Securities and the home loan rates tied to them. Global Bond yields are also moving higher, which can negatively impact home loan rates as well.
With both technicals and fundamentals working against Mortgage Backed Securities and home loan rates, I recommend locking your mortgage rate for purchases or refinances sooner than later.
As of now, interest rates are starting at 3.75% APR for all loan amounts. Down payment, loan program, and property type are a few variables that will effect final interest rate.
