Frequently asked questions

You’ve got questions, we’ve got answers

How is PrePay smarter than making payments myself?

Because savings compound over time, initial prepayments are worth 5-8x more than last prepayments on a 30yr loan. Paying the same amount each month isn't best for you. $100 invested in year 1 is worth $447 (when rates are 5%) but the same $100 invested in year 20 is only worth $163. The bulk of PrePay happens in the first 5 years and declines to 0 by year ~10-12.  You'll invest ~30% less and save ~45% more vs bi-weekly payments

What is your service fee?

Our fees are less than a fancy cup of coffee (on avg.) and 3% of your extra payment. On a prepayment of $279 you'll pay ~$8.1 in fees. As your prepayment decreases each month, so do our fees. We also use these fees to help operate the Altgage platform securely, develop innovative products and reach more homeowners.

Altgage PrePay is not your loan servicer

You retain 100% responsibility to continue making minimum monthly payments to your mortgage servicer. We only optimize and automate extra payments to principal that decrease every month.  You can turn off PrePay and return anytime.

Remember to check with your mortgage servicer for any prepayment penalties if you have a non-qualified mortgage like a DSCR, interest only or hard money loan. Qualified mortgages in the US do not typically have prepayment penalties

Can't I pay extra directly with my bank?

Yes you can, but extra payments with your bank are not dynamic or smart. The three most common ways to pay extra are

  1. Bi-weekly payments: instead of making 12 monthly payments, bi-weekly payments split your monthly payment in two and pay it every other week. Since there are 26 two week periods in a year, you'll effectively make a 13th full payment, with a little sleight of the calendar.
  2. 1 extra payment a year: If you get paid monthly or receive a bonus at the end of the year, making a single extra payment will also cut your mortgage short similar to bi-weekly payments. Paying at the end of the year will save you less vs paying upfront.
  3. Fixed extra payments: do not vary every month. They are predictable but have the least impact on your mortgage unless your are paying more than than your monthly payment/12.

Since savings compound over time, initial prepayments are worth 5-8x more than last prepayments on a 30yr loan.
