Bar graphs are used to compare things between different groups or to track changes over time. However, when trying to measure change over time, bar graphs are best when the changes are larger. . . . an Area Graph. Area graphs are very similar to line graphs.
The typical bank limit on monthly mortgage payments is about 28 percent of your gross monthly income. Therefore, the bank thinks you can devote up to 28 percent of your household income to your mortgage payment and expenses (including taxes, insurance and association dues).
For a conventional home loan (one that is not insured by the government), mortgage lenders typically cap the front-end DTI ratio somewhere between 28% and 30%. That is the maximum percentage of income that can go toward mortgage payments. Again, this is just a rule of thumb used by most lenders -- it's not set in stone. Some lenders will allow a higher percentage to go toward monthly payments. But the 28% rule has long been a standard within the lending industry.
