Let's walk through a practical example. Enter realistic numbers based on your situation, then adjust one variable at a time to see how it affects the outcome. For instance, try changing the interest rate by 0.5% or extending the term by 5 years — you'll immediately see how small changes can have significant financial impacts over time.

A DTI under 36% is considered good by most lenders. Under 28% for housing alone (front-end) is ideal. For example, at $75,000 income ($6,250/month), keep housing under $1,750 and total debt payments under $2,250.
Three ways: (1) Increase income — a side gig or raise helps. (2) Pay down debt — focus on the highest monthly payment first for maximum DTI impact. (3) Refinance high-interest loans to lower monthly payments. Reducing a $400/month car payment to $300 saves $100/month in DTI.
Current rent does NOT count toward DTI for mortgage applications — only the projected future mortgage payment counts. However, lenders look at your rental payment history as evidence you can handle housing costs.
