Step 1: Comprehensive Qualification
Qualification analysis is the foundation of every loan conversation. Within minutes of getting a borrower's income, debts, and credit score, you should know their maximum purchase price, which programs they qualify for, and the potential deal-breakers. This calculator does the heavy lifting.
Key Concepts
- DTI Limits by Program — Conventional: 45% back-end (50% with strong compensating factors). FHA: 43–57% depending on credit and reserves. VA: 41% guideline, flexible with residual income. USDA: 41% back-end.
- Compensating Factors — High credit score (740+), significant reserves (6+ months), low LTV, stable employment history, and minimal payment shock can push DTI limits higher.
- AUS Findings — Desktop Underwriter (DU) and Loan Prospector (LP) approve or deny based on the full picture. A borrower at 47% DTI might get an Approve/Eligible with strong comp factors.
- Pre-Qualification vs. Pre-Approval — Pre-qual is a conversation. Pre-approval runs credit, verifies income, and gets an AUS approval. Smart agents want the latter.
What to Look For
- Run the numbers at multiple price points. Show the borrower their "comfortable" and "maximum" purchase prices. Under-promise and over-deliver on buying power.
- Identify the binding constraint: is it DTI, down payment, credit score, or reserves? This tells you what the borrower needs to improve for a stronger approval.
- Check qualification across multiple programs simultaneously. A borrower who doesn't qualify conventional at 5% down may qualify FHA at 3.5% with a higher DTI allowance.
Step 2: Evaluating DSCR Loans
DSCR (Debt Service Coverage Ratio) loans are the fastest-growing segment of investor lending. Unlike conventional loans, they qualify based on the property's income — not the borrower's personal income. Understanding these products positions you to serve the growing investor market.
Key Concepts
- DSCR Calculation — Gross Rent / PITIA (Principal, Interest, Taxes, Insurance, HOA). A DSCR of 1.25 means rent covers 125% of the payment. Most lenders require 1.0–1.25 minimum.
- Rate Adjustments — DSCR pricing depends on: DSCR ratio (higher = better rate), LTV (lower = better), credit score, property type (SFR best, multi-unit higher), and prepay term selection.
- No-Ratio / Low-DSCR — Some lenders offer "no-ratio" programs for properties under 1.0 DSCR, but at significantly higher rates (1–2% premium). These are for appreciation plays, not cash-flow deals.
- Rent Verification — Lenders accept existing leases, market rent studies (Form 1007), or AirDNA for short-term rental properties. The rent source matters for underwriting.
What to Look For
- Model the DSCR at different rent assumptions (current lease, market rate, conservative). The lender uses the lower of lease-in-place or market rent — make sure your estimate aligns.
- Compare DSCR pricing across lenders. Rate spreads of 0.5–1% between DSCR lenders are common. Shop at least 3 sources for the best execution.
- Calculate the break-even rent: what rent is needed for a 1.0 DSCR? If market rent is above this, the deal works. If not, you need a higher down payment or lower price.
Step 3: Government Program Eligibility
FHA, VA, and USDA loans serve specific populations with benefits that conventional loans can't match: lower down payments, more flexible credit requirements, and competitive rates. Knowing the eligibility rules cold makes you invaluable to first-time buyers, veterans, and rural borrowers.
Key Concepts
- FHA Deep Dive — 3.5% down at 580+ FICO. Upfront MIP (1.75% of loan) + annual MIP (0.55–1.05% depending on term and LTV). MIP is permanent on 30-year loans with less than 10% down. Manual underwrite available for non-traditional credit.
- VA Entitlement — Full entitlement = no loan limit. Partial entitlement (if prior VA loan still active) has county-based limits. Funding fee: 1.25–3.3% depending on service type, down payment, and prior usage. Disabled veterans are exempt.
- USDA Rules — No down payment. Income must be below 115% of area median. Property must be in USDA-eligible area (more locations than you'd think). Guarantee fee: 1% upfront + 0.35% annual.
- Loan Limits — FHA and conforming limits vary by county. High-cost areas can exceed $1M for conforming. Always check the current year's limits for your county.
What to Look For
- Compare FHA vs. conventional at each credit score tier. Above 720 FICO with 5%+ down, conventional often wins on total cost. Below 680, FHA usually provides better pricing and higher approval rates.
- For VA borrowers: calculate the funding fee impact. A 2.15% fee on a $300K loan = $6,450 added to the loan. Disabled veterans save this entirely — always verify disability status.
- Model the MIP removal scenario for FHA: if the borrower puts 10% down, MIP drops off after 11 years. If less than 10%, it's permanent. Show the borrower the 30-year cost difference.
Step 4: Rate Buydown Strategy
Rate buydowns are one of the most powerful tools in a loan officer's arsenal — especially when rates are high. Whether it's permanent discount points, a temporary 2-1 buydown, or a 3-2-1 buydown funded by the seller, understanding these structures helps you close deals that would otherwise fall apart.
Key Concepts
- Permanent Buydown (Points) — 1 point = 1% of loan amount = ~0.25% rate reduction. On a $300K loan: 1 point costs $3,000 and saves ~$50/month. Break-even: ~5 years. Only worth it if the borrower will keep the loan 5+ years.
- 2-1 Temporary Buydown — Year 1: rate is 2% below note rate. Year 2: 1% below. Year 3+: full rate. Seller or lender credits fund the subsidy account. The borrower qualifies at the full note rate.
- 3-2-1 Buydown — Same concept, but starts 3% below note rate. More expensive to fund but more dramatic first-year savings. Great marketing tool in high-rate environments.
- Seller-Funded Buydowns — Instead of a $10K price reduction, the seller funds a 2-1 buydown. The borrower saves more on monthly payments than a price cut would provide. Win-win positioning.
What to Look For
- Calculate the break-even on permanent points. If the borrower plans to refinance in 2–3 years (expecting lower rates), points are wasted money. Temporary buydowns are better in a declining rate environment.
- Model the 2-1 buydown subsidy cost vs. a price reduction. A $6,000 2-1 buydown saves the borrower ~$400/month in Year 1 and ~$200/month in Year 2. A $6,000 price reduction only saves ~$35/month. The math strongly favors the buydown.
- Present buydown scenarios to agents as a deal-saving tool. When a buyer says "I can't afford the payment," a seller-funded buydown can bridge the gap without changing the sale price — protecting the seller's net and the agent's commission.
