First-Time Home Buyer
The 2026 math.

Most first-time-buyer content optimizes for clicks, not for your closing statement. This is the working math: what closing costs actually total, why 5% down often beats 3%, and how PMI drop-off interacts with your refinance window.

The Real All-In Cost

List price is not the number you'll write a check for. On a $400,000 conventional purchase with 5% down, the actual cash needed at closing typically runs:

Down payment: $20,000
Lender fees (origination, underwriting, processing): $1,800–$3,500
Third-party fees (appraisal, credit, flood cert): $700–$1,200
Title insurance & settlement: $1,400–$3,000 depending on state
Recording & transfer tax: $400–$4,500 (varies wildly by jurisdiction)
Prepaid items (escrow setup for taxes & insurance, per-diem interest): $4,000–$7,000
Homeowner's insurance (first-year premium, often paid up front): $1,200–$2,400

Total cash needed for a $400k purchase at 5% down: roughly $30,000–$40,000, not $20,000. Plug a realistic closing-cost figure into the mortgage calculator before you start touring houses.

LTV Thresholds That Move the Rate

Loan-to-value (LTV) is the loan amount divided by the appraised value. Lenders price loans in tiers:

≤ 60% LTV: best rate, typically 0.125–0.250% below the par rate
60–75%: par rate
75–80%: par to +0.125%
80–90%: +0.125 to +0.25% AND PMI required
90–95%: +0.25 to +0.50% AND higher PMI
95–97%: conventional only via Fannie/Freddie 97% programs, highest PMI tier

The implication: putting 5% down instead of 3% shaves PMI by roughly 30–40% and can drop you under the 95% LTV cliff. On a 30-year, $380k loan, that's typically $40–$70 per month — about $15,000–$25,000 over the life of the loan.

FHA vs. Conventional 97

FHA allows 3.5% down with credit scores as low as 580. Conventional 97 (Fannie/Freddie HomeReady or HomePossible) allows 3% down with a 620 minimum and income limits in some metros.

Headline rates are usually similar. The difference is in the insurance:

FHA: 1.75% upfront mortgage insurance premium (UFMIP) plus 0.55% annual MIP. The annual MIP never goes away on loans with less than 10% down, even after you cross 20% equity.
Conventional PMI: 0.3% to 1.5% annual depending on credit/LTV. Drops automatically when LTV reaches 78% (by amortization) and can be canceled at 80% LTV by appraisal.

Rule of thumb: if your FICO is ≥ 680 and you can produce 5% down, conventional almost always wins long-term because PMI ends. If your FICO is 580–660, FHA is usually the only door open.

PMI Drop-Off Strategy

On a 30-year amortization, you cross 80% LTV (assuming flat home value) at roughly month 113 — 9.4 years in. With 4% appreciation (the long-run national average), you typically cross 80% by year 5–6. After that you can request a PMI drop on appraisal — total cost $400–$600 — and save $100–$300/month.

Set a calendar reminder for year 4 to check your LTV. Most servicers won't proactively cancel PMI; you have to ask.

The Rate-Lock Window

Once you're under contract, you'll typically lock the rate for 30–60 days. Float-down provisions cost 0.125–0.25% in fee but let you re-lock if rates drop more than 0.25% before closing. In a falling-rate environment, take the float-down. In a rising one, lock immediately and choose the longer window.

What to Run Through the Calculator

Take your conservative purchase budget (max of 28% gross income on PITI).
Plug it into the mortgage calculator with realistic property tax (1.0–2.5% of price by state) and insurance ($800–$2,500/yr by state).
Run two scenarios: 3% down with PMI vs. 5% down with PMI. Compare total interest + PMI through year 7 — the typical move-or-refi window.
Stress-test by adding 1% to the rate. If the payment becomes uncomfortable, you've over-borrowed.
