A mortgage under $150,000
Loans this size are common for starter homes in lower-cost areas and for manufactured homes or condos. Some lenders charge a minimum fee or set a minimum loan amount, so small loans can carry a higher effective rate. Closing costs are a larger share of the loan, so check the loan estimate carefully.

A $100,000 loan at 6.5% over 30 years has a principal-and-interest payment of $632.07 and $127,543 of interest, which is 128% of the loan. Over 15 years at 5.9% the payment is $838.46 and the interest $50,924. The 15-year saves $76,619.
$100,000 loan: 15-year vs 30-year
On a $100,000 mortgage, a 30-year loan at 6.5% costs $632.07 a month in principal and interest and $127,543 in total interest. A 15-year loan at a rate about 0.6 points lower costs $838.46 a month, $206.39 more, but cuts the interest to $50,924, saving $76,619. The right choice depends on whether the higher payment fits your budget with room to spare.

| 30-year at 6.5% | $632.07 | $127,543 | $227,543 |
What each 6.5% ± 1 point does to the payment
A one-point change in your mortgage rate moves the payment on $100,000 by roughly $67.14 a month and the lifetime interest by about $24,179 over 30 years. That is why it pays to compare several lenders on the same day.
| Rate | Principal & interest | Total interest | Difference vs 6.5% |
|---|---|---|---|
| 5.5% | $567.79 | $104,403 | −$23,140 |
| 6% | $599.55 | $115,838 | −$11,705 |
| 6.5% | $632.07 | $127,543 | +$0 |
| 7% | $665.30 | $139,511 | +$11,968 |
| 7.5% | $699.21 | $151,722 | +$24,179 |
Down payment and PMI on a $125,000 home
With less than 20% down, lenders charge private mortgage insurance (PMI), commonly 0.3% to 1.5% of the loan per year. This page assumes 0.6%. PMI usually ends when you reach 80% of the home's original value, which you can reach sooner with extra payments.
| Down payment | Loan amount | PMI / month | Total monthly payment |
|---|---|---|---|
| 5% ($6,250) | $118,750 | $59.38 | $1,049.54 |
| 10% ($12,500) | $112,500 | $56.25 | $1,006.91 |
| 20% ($25,000) | $100,000 | $0.00 | $871.65 |
What income does a $125,000 home need?
Lenders often look at a front-end ratio of about 28% of gross income for housing costs. A total payment of $871.65 implies a gross income near $37,000 a year, and lenders also weigh your other debts, which usually must keep total payments under about 36% to 43% of income.
Year one is interest-heavy: $6,467 of interest against $1,118 of principal repaid, which is why extra payments early on have the most effect.
How fast you build equity
Equity here is the home price minus the loan balance, assuming the price stays flat. Appreciation, if any, would add to it.
| After | Loan balance | Principal repaid | Equity (flat value) |
|---|---|---|---|
| 5 years | $93,611 | $6,389 | $31,389 |
| 10 years | $84,776 | $15,224 | $40,224 |
| 15 years | $72,559 | $27,441 | $52,441 |
| 20 years | $55,664 | $44,336 | $69,336 |
