Financing Your First Investment Property

Worksheet · Author: Austin Coon

Financing decides more about your first deal than the property does: it sets your down payment, your rate, your payment, and therefore your entire cash flow. Most first-time investors only price one path — this worksheet prices all of them.

The core principle: owner-occupied loans are dramatically cheaper than investor loans, and the strategies that qualify you for them (house hacking above all) are the cheapest entries into real estate.

The four paths

  • FHA (owner-occupied, 1–4 units): 3.5% down with a 580+ credit score; carries upfront and monthly mortgage insurance. The classic house hack loan.
  • Conventional (owner-occupied): as low as 5% down with PMI that drops off at 20% equity; stricter qualifying than FHA on multi-unit.
  • Conventional investment property: 15–25% down, higher rates, no occupancy requirement.
  • Commercial (5+ units): 20–30% down, 20–25 year amortization, and the property must qualify through DSCR — most lenders want 1.20–1.25×.

The math that decides affordability

  • On a $150,000 30-year loan, the payment moves from roughly $805 at 5% to roughly $998 at 7% — a $193 monthly swing that can flip a deal’s cash flow.
  • Lenders credit about 75% of documented rental income toward qualifying on owner-occupied multi-unit purchases.
  • Budget roughly 2% of the price for closing costs on top of your down payment.

Before you shop

  • Ask Austin for a lender introduction — pricing all three owner-occupied paths takes one conversation.
  • Get pre-approved before touring, not before offering; sellers take pre-approved buyers seriously.
  • Rerun every deal at +1% interest. If it only works at today’s rate, it doesn’t work.

Common questions

Do I have to put 20% down?

Only on a pure investment purchase without an owner-occupied strategy. Live in the property and 3.5–5% paths open up — that single decision changes the required cash by tens of thousands of dollars.

Can I use rental income to qualify?

Usually 75% of documented rents from units you won’t occupy — via existing leases or the appraiser’s market-rent estimate on owner-occupied multi-unit loans.

What about 5+ units?

That’s commercial: the property’s NOI must cover debt service 1.20–1.25×, amortization shortens to 20–25 years, and lenders will haircut your NOI to market vacancy. The Commercial Underwriting Model on this site runs that math.
