Do not hide it in “other.” [Home](/)[Learn](/learn/)CreditCredit Educational [← Mortgage learning hub](/learn/) Front-end DTI is the housing payment — principal, interest, taxes, insurance, and HOA when the property has dues — divided by gross monthly income. Back-end DTI is that housing payment plus the other debts the investor counts. A townhome or condo with a “cheap” note payment can still fail because HOA is housing, not a footnote.

Confirm the guide for the product.QuestionFront-end (housing)Back-end (all counted debts) What is in the ratioFront-end DTI is housing payment (PITI plus HOA if applicable) divided by gross monthly income.Back-end DTI is all counted monthly debts divided by gross monthly income. Where HOA sitsHOA dues that are required for the subject property are housing expense. They sit in front-end DTI with principal, interest, taxes, and insurance — not in the “other debts” box of an affordability toy.Back-end DTI still includes that housing payment plus counted installment, revolving, and other debts. A condo with a modest PITI and a large HOA can fail DTI even when the note payment looks comfortable. What it is notHOA is not mortgage insurance. PMI/MIP can change with LTV or program. HOA is set by the association and can rise after you close.Student loans, auto loans, and revolving minimums are typically back-end lines, not HOA. Count them where the investor says. Affordability calculators that omit HOA will overstate a condo budget. Enter the association’s current dues, not a guess of zero. ## Why condos surprise people A special assessment or pending litigation at the project is a property-eligibility question as well as a payment question. It is not the same line as regular HOA dues. FHA condos also need project approval — [FHA condo roster](/blog/fha-condo-roster-project-approval/) — which is not a DTI test but can kill the same contract. Variable income is averaged _before_ these ratios are run: When income is overtime, bonus, commission, or 1099, underwriters typically average a documented history (often 12–24 months) rather than using the highest recent month. Student loans have their own counting rules: [IDR / SAVE and DTI](/blog/student-loans-dti-idr-save/). ## How to use the calculator without lying to yourself The [affordability calculator](/calculators/affordability/) is an illustration. Put HOA in the housing box. The [payment calculator](/calculators/mortgage-payment/) should include the same dues if you are comparing a condo to a single-family house. Neither tool is underwriting. ## What happens next - Ask the listing or HOA for the current monthly dues and whether a special assessment is pending. - Re-run DTI with PITI + HOA as housing, plus car and student loans as counted debts. - If the building is a condo and you hoped for FHA, look up the project before you write the offer. Then talk with a loan officer — that conversation is not a credit decision. ## Common questions ### Is HOA part of front-end or back-end DTI? ### Does a high HOA automatically kill a condo file? ## Keep going [Home affordability calculator Estimate a price range from income, debts, and expenses.
