Not too likely and if it happened it would be after years of careful saving and planning. Let's say you manage to save 20% as a down payment, $100,000. That would mean, at today's interest rates, a little over $2,000 a month in mortgage payments. Add in property taxes, insurance, utility bills, and you're looking at a minimum of another $500 a month. Those things can vary considerably depending where you are. It could be much more. It isn't likely to be less. And we haven't even figured in normal maintenance and repair expenses.
The amount of mortgage you can qualify for is based on how much you earn. To qualify for a mortgage of $2,000 a month, you'd have to earn at least 3 times that, $6,000 a month or $72,000 a year.
Median salary for a flight attendant in the US is around $55,000. Half will make more than that, half will make less. How much you make depends where you work, your qualifications and your seniority. Take-home pay would be a little over $3,000. On a flight attendant's median salary, you would be barely able to pay the basic expenses for a $500,000 home as well as paying for food, never mind anything else like clothes. And you wouldn't qualify for a mortgage in the first place.
