Key takeaways

  • Define a buy box before viewing a single property.
  • Get pre-approved for financing before making offers.
  • Your first property should be boring and conservative.
  • Local property managers are usually worth the 8–10%.
  • Build the operating spreadsheet before closing, not after.

Core concepts

The buy box

A one-page document: price range, location, property type, condition, return targets. Refuse to look at anything outside it.

Financing readiness

Pre-approval signals seriousness. Conventional, DSCR, and portfolio loans each have a fit — pick before shopping.

The pro forma

A spreadsheet that converts rent and expenses into cash-on-cash, DSCR, and reserves. Build it once, reuse forever.

First-year operating plan

Lease template, screening criteria, maintenance vendors, and a reserve account opened before close.

Step-by-step framework

  1. 1Write a one-page buy box and stick to it.
  2. 2Get conventional or DSCR pre-approval in writing.
  3. 3Underwrite 20 deals; offer on the best three.
  4. 4Inspect every property before contract — never skip.
  5. 5Close with reserves >= 6 months PITI in a separate account.
  6. 6Onboard a property manager before first tenant placement.

Common mistakes to avoid

  • Buying the first thing you see because it's exciting.
  • Stretching reserves to make the down payment.
  • Skipping inspection to win the offer.
  • Picking the wrong financing because it was offered first.

Frequently asked questions

How much do I need to start?

Conventional: 20–25% down + 6 months reserves. On a $200k property: roughly $50–60k all-in.

Should I start with a duplex?

Often yes — house hacking a duplex compounds learning and reduces personal housing cost.

Do I need an LLC for property one?

No. Liability insurance plus an umbrella policy is sufficient until property 2–3.
