Home value you'd need
Home value needed for a $150,000 line at an 85% combined loan-to-value cap:
| Mortgage balance | Home value needed |
|---|---|
| $0 | $176,471 |
| $150,000 | $352,941 |

What $150,000 usually pays for
A $150,000 line often funds a detached ADU in lower-cost areas, an addition, or a buyout in a divorce. Lenders may require a full appraisal and look harder at income at this size, since a payment on the full line can be over $1,000 a month. If you'll draw it all at once and hold it for years, compare a fixed home equity loan and a cash-out refinance.
Paying it off faster
On $150,000 at 7.75% over a 20-year payoff, the payment is $1,231 and total interest is $145,541. Adding a little each month shortens the payoff and cuts interest:
| Extra each month | New payment | Paid off in | Interest saved |
|---|---|---|---|
| +$50 | $1,281 | 18.3 years | $14,762 |
| +$100 | $1,331 | 16.8 years | $26,571 |
| +$250 | $1,481 | 13.7 years | $51,355 |
Income you'd need to qualify
Many lenders qualify you on the full payoff payment, about $1,231 a month here, inside a roughly 43% debt-to-income cap. Income needed, by what your other debts already take:
| Your other debts and housing costs | Gross income needed | Per year |
|---|---|---|
| 20% of income | $5,354/mo | $64,248/yr |
| 25% of income | $6,841/mo | $82,095/yr |
| 30% of income | $9,472/mo | $113,670/yr |
| 35% of income | $15,393/mo | $184,713/yr |
Illustration only; lenders differ in how they calculate the HELOC payment and which debts they count.
