Transient is the most hyped, abused and trendy word in GS. A transient is a short-duration signal that represents a nonharmonic attack phase of a sound source. It contains a high degree of nonperiodic components and a higher magnitude of high frequencies than the harmonic content of that sound.
But like any estimate, it's based on some rounded numbers and rules of thumb. For example, this mortgage affordability calculator assumes that your monthly mortgage payment should be no more than 28% of your monthly income, to leave enough money for other expenses and investments you'll want to make.
Sounds weird, doesn't it? But think how much fun that would be! No mortgage! No payments! If paying cash for a house seems too far out of reach, you can still buy a house if you make wise choices. Save a down payment of at least 10% on a 15-year (or less) fixed-rate mortgage, and limit your monthly payment to 25% or less of your monthly take-home pay. You can probably qualify for a much larger loan than what 25% of your take-home pay will give you. But it's not wise to spend more on a house because then you will be what Dave calls house poor. Too much of your income will be going out in payments, and that will put strain on the rest of your budget. You won't be able to save and pay cash for furniture, cars and education. The really interesting thing about 15-year mortgages is that they always pay off in 15 years. Thirty-year mortgages are for people who enjoy slavery so much they want to extend it for 15 more years and pay thousands of dollars more for the privilege. If you must take out a mortgage, pretend only 15-year mortgages exist.
