San Diego-based independent mortgage lender Guild Mortgage loaned homebuyers $15.9 billion in 2016, 15.3 percent more than the $13.8 billion it loaned out in the prior year, the company announced Tuesday.

Guild has grown dramatically in recent years, nearly quadrupling its loan volume since 2010. That growth has been bolstered by the company’s geographic expansion: at the end of 2016, Guild had 234 branches in 25 states, up from 75 branches in 16 states in 2010.

The company’s servicing volume also grew, reaching $29.9 billion in 2016, 34.1 percent more than in 2015.

The number and size of loans Guild closed in 2016 both increased, rising 10.3 percent to 69,885 from 63,358 in 2015 and 4.6 percent to $228,404 per loan from $218,381 in 2015, the company said.

Of the states in which Guild operates, California had the largest loan volume last year, notching up $3.3 billion. Loan volume in the Southeast region, which spans the states of Georgia, Florida, Tennessee and Arkansas, grew the most among the regions in which the company operates: the total there hit $992.6 million, up 48.4 percent from $668.7 million in 2015, Guild said.
