Mortgage affordability and qualification
Calculate exact maximum purchase prices, monthly payment breakdowns, and front-end/back-end DTI ratios for borrowers at different income and debt levels. Model multiple rate scenarios so borrowers understand how rate changes affect their buying power.
My borrower earns $115,000/year, has $1,200/month in existing debt (car + student loans), and can put $40,000 down. Current rate is 7.0%. What can they afford on a 30-year fixed? Show front and back DTI.
At 7.0% / 30 years: Max loan at 28% front DTI = $274,000. Max loan at 43% back DTI = $272,000 (binding — existing debt is the constraint). Max purchase price: ~$312,000 with $40K down. Monthly payment: $1,813 P&I, ~$312 taxes/insurance (estimated), ~$115 PMI. Total PITI: ~$2,240. Buyer should know: dropping rate by 1% adds ~$28K in buying power.

Compare loan options for a veteran buying a $385,000 home in San Antonio with a 680 credit score and $20,000 saved for closing/down. Compare VA, FHA, and conventional 5% down.
VA Loan: 0% down, 2.15% funding fee ($8,278, typically financed), no PMI, ~7.0% rate. Payment: $2,668/month. FHA: 3.5% down ($13,475), 1.75% UFMIP + 0.85% annual MIP, ~7.0% rate. Payment: $2,831 including MIP. Conventional 5% down ($19,250): PMI at ~0.7% annually, 7.25% rate. Payment: $2,912 including PMI. Winner for this profile: VA — saves $150–250/month vs. alternatives and preserves cash reserves.
Rate and market timing research
Pull current mortgage rates, monitor the FOMC calendar, and translate Fed policy expectations into plain-English rate guidance for clients. Help borrowers decide whether to lock now or float their rate.
My borrower is trying to decide whether to lock their 7.25% rate today or float hoping for a drop. What does the FOMC calendar say and what are markets pricing in?
Current 30-year: 7.12% (down from 7.31% last week). Next FOMC: May 6-7. Markets pricing a 62% probability of a 25bp cut at the June meeting. 10-year Treasury at 4.38%. Outlook: rates may drift 10-15bp lower over 60 days if CPI cooperates, but there's meaningful upside risk from strong jobs data. For a 30-day close, locking now looks prudent — the potential savings don't justify the risk.

Frequently Asked Questions
What DTI ratios do conventional loans require vs FHA loans?
Conventional loans (Fannie/Freddie) allow up to 45% back-end DTI with automated underwriting approval, sometimes up to 50% with compensating factors like high credit score or large reserves. FHA is more flexible — guidelines allow up to 57% with AUS approval, though many lenders overlay a 50% cap. Always quote conservative DTI targets to clients: 36-43% is where rates are most competitive.
When does PMI drop off on a conventional loan?
By law (Homeowners Protection Act), lenders must automatically cancel PMI when the loan balance reaches 78% of the original purchase price, based on the original amortization schedule. Borrowers can request cancellation at 80% LTV if they can document no 30-day late payments in the prior 12 months. A new appraisal showing appreciation can accelerate this on loans originated before 2014.
How do I help a buyer decide between locking and floating?
For purchase loans, the key variable is close date certainty. If closing is within 30 days and the current rate is acceptable, lock — the cost of the rate going up typically outweighs the benefit of a small drop. For longer pipelines (45-60 days), factor in: where the 10-year Treasury is relative to its recent range, the Fed calendar, and whether major economic data releases are upcoming.
What is the conforming loan limit for 2026?
The 2026 conforming loan limit (baseline) is $806,500 for single-family properties in most US counties. High-cost areas (Hawaii, Alaska, and metros like NYC, LA, San Francisco) have higher limits — up to $1,209,750. Loans above the limit are jumbo loans, which typically carry rates 0.25-0.75% higher than conforming rates.
What income documentation is required for a self-employed borrower?
Self-employed borrowers (>25% ownership in a business) need 2 years of personal tax returns (1040 with all schedules), 2 years of business tax returns, a year-to-date profit and loss statement, and a CPA letter confirming the business is active. Income is calculated from the 2-year average of Schedule C net income, K-1 distributions, or W-2 wages from the business — whichever applies.
