Frequently Asked Questions
What’s the difference between APR and interest rate?
Your interest rate is the base cost of borrowing — the percentage applied to your loan balance. APR includes the interest rate plus lender fees, discount points, and other costs, expressed as a yearly percentage. APR is always equal to or higher than your interest rate. When comparing loan offers, APR gives a more complete picture of total borrowing cost. Our loan comparison calculator shows how these numbers affect your bottom line.
Do I need to memorize all of these acronyms?
Not at all. The ones you’ll encounter most frequently during a purchase are DTI, LTV, PMI, PITI, EMD, and HOA. Bookmark this page and reference it when you hit an unfamiliar abbreviation in your loan documents or agent correspondence. Your lender and agent should explain anything you don’t understand — never sign documents with unresolved questions.
Which loan type is best for first-time buyers?
It depends on your situation. Conventional loans with 3% to 5% down work well for buyers with credit scores above 700. FHA loans accept lower credit scores (580+) with 3.5% down. VA loans are the best deal available if you qualify — 0% down and no PMI. USDA loans offer 0% down for eligible rural properties. Compare all options with at least three lenders to find the best fit for your credit profile and budget.
