The 3-Unit Rental Portfolio: Reserves + LLC Question

The third property is where operators start seriously considering an LLC. Two properties in personal name is fine. Three, with growing equity, is when the litigation-exposure math starts to change.

Reserves per property
6 months PITI
Fannie/Freddie requirement past 4 financed

Financing gets tight

Conventional lenders start requiring 6 months of PITI in reserves per financed property once you hit 4-6 financed properties. At 3 units that clock is ticking. Rate premiums for investor loans (0.75-1.25% over primary residence rates) compound over the portfolio life.

The LLC question

At 3+ properties, umbrella-only starts feeling thin. Common structures: (1) each property in its own LLC (max protection, max drag), (2) all rentals in one LLC (balanced), (3) series LLC where state law allows (efficient but state-specific). Talk to a real estate attorney — the right answer depends on your state and your risk profile, not on internet advice.

Bookkeeping stops being optional

A single spreadsheet works for 1-2 properties. At 3, you want either QuickBooks or a purpose-built landlord tool like Stessa. Tax prep gets faster, mid-year decisions get better, and you catch expense creep before it eats into cash flow.

Common mistakes at 3 units

  • ×Choosing LLC structure based on YouTube advice instead of a state-specific attorney
  • ×Not building reserves ahead of the 4th-property reserve requirement
  • ×Trying to self-manage 3 units in a metro you don't live in
  • ×Ignoring how mortgage rates on the 3rd loan differ from the 1st (they will be higher)

What changes at the next scale

At 5 units, portfolio loans become viable and often preferable. One loan on 5 properties beats 5 loans on 5 properties for documentation, DTI treatment, and rate stability.

Track a 3-unit portfolio with real numbers

The Pro Portfolio Tracker rolls up every property, auto-revalues them against local price data, and flags DSCR risk + equity milestones. At the 3-unit scale you should already be tracking your portfolio somewhere — this is the projection-native option most bookkeeping tools don’t cover.

Playbook informed by operator experience across scales. Every portfolio is different; treat this as one perspective, not the definitive answer for your situation.
