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.
Your lender doesn't know about that, so the $1,400 mortgage it says you qualify for today may not fit your actual budget in five years -- particularly if you don't see your income increasing too much over that period. Take a look at this calculator to see how much house you can afford based on your current income. In general, it's more difficult to qualify for a mortgage now than it was during the housing boom, when just about any motivated homebuyer could find credit -- even many who couldn't afford to buy a house.
