How much equity Williams Bay owners could borrow
Home equity is what your home is worth minus what you owe. Most lenders let you borrow until your loans add up to 80% to 85% of the home's value. For the median Williams Bay home of $444,700, 80% is $355,760.
43% of Williams Bay owners have no mortgage at all, so they could borrow up to the full 80% limit.
Owners with a mortgage here already spend a median $2,042 a month on housing, so a new payment should fit next to that. At the median income of $84,113, lenders typically cap all debt payments at about 43% of gross income, or $3,014 a month.
If you instead refinance and take cash out, the whole loan moves to the new rate (this week's 30-year average is 7.11%). A home equity loan or line of credit keeps your current first mortgage, which is usually better when your existing rate is lower than today's.
