Limited Time Conventional 7/6 Adjustable Rate Mortgage (ARM) with a 2-1 Temporary Buydown available on select quick move-in homes at Amplitude by Shea Homes (San Marcos, CA). The 2-1 Temporary Buydown is where a portion of the payment for the first two years is prepaid by the Seller via incentive (placed in a custodial escrow account). The temporary payment rate is 2% lower than the note rate for the first year of the loan and 1% lower than the note rate for the second year of the loan. The initial note rate is 4.875% / 6.186% APR, fixed for the first seven years of the loan (84 months).

After the initial 7 year period, the variable interest rate and payment will adjust every 6 months and equal the 30 Day Average SOFR (Secured Overnight Financing Rate) plus a margin of 2.75%.

The maximum change in the interest rate is up to 5% at the first adjustment, up to 1% with every subsequent periodic adjustment, with a maximum lifetime adjustment of 5% (maximum lifetime interest rate of 9.875%), and your payment will increase.
