You can get a 2,000 SF house for $135k. Someone making $36k could easily afford this house.
135,000 * .06 (6% for interest) = $143,100 - but then again, insnt the interest compounded yearly?
30 year mortgage * 12 payments per year = 360 payments
143,000 / 360 = 397.22 + home owners insurance + property tax + any property owners association fees
Lets just round that off to $600 a month.
~~~~~~~~~
36,000 - 25% for all taxes (sales tax, income tax, social security, medicare/medicaid, medical insurance, 401k deductions) = $27,000 spendable income.
$27,000 / 12 months= $2,250 per month
~~~~~~~~~
Is the person paying child support? If so how many children is he/she paying on? That is another 20% - 25% gone off the salary after taxes.
~~~~~~~~~
$300 a month for heating cooling expenses
$600 for car note and insurance
$200 for gas
$500 for food
$600 for house note
$2,200
That leaves you with maybe $50 free for the month.
I do not call that "easily" being able to afford a house.
If the person is divorced and has 1 child, subtract 20% off their monthly wages, plus half any medical expenses for the child.
Does the persons job provide insurance? If not, and the person is divorced, subtract medical off of their monthly salary.
