Getting Started
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.
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.
