The 1-Unit Rental Portfolio: First Property Playbook
The first rental property is the simplest configuration and the highest per-hour learning curve you'll ever have as a landlord. This is where you learn what expenses actually look like, how tenants actually behave, and whether the underwriting spreadsheet matched the reality.
Financing at 1 unit
A single non-owner-occupied rental almost always finances through a conventional Fannie Mae or Freddie Mac loan — 20-25% down, 30-year fixed, standard DTI review. Owner-occupied gets FHA/VA options at lower down (with the trade-off of living there for a year). The rate spread over primary residence is usually 50-75 basis points.
Structure and taxes
Personal name ownership is standard. LLC at 1 unit is usually overkill — an umbrella insurance policy at $1M–$2M costs a fraction of the transaction and legal drag of an LLC transfer. Schedule E on your personal return; depreciation, mortgage interest, taxes, insurance, repairs all flow through.
Management
Self-management at 1 unit is educational and almost always net-positive economically. Fixing your own toilet is not the point — reading a lease application accurately, understanding what a maintenance emergency actually looks like, and building the tenant-management muscle memory is.
Common mistakes at 1 unit
- ×Underestimating vacancy — one bad tenant turn can eat a full year of cash flow
- ×Skipping reserves — 3-6 months of PITI in a separate account per property, always
- ×Buying on gross rent yield without modeling actual operating expenses
- ×Rushing into an LLC before there's any asset to protect
What changes at the next scale
At 2 units, DTI starts to bite. Conventional lenders count 75% of gross rent against the mortgage payment; if the second property is close to break-even, your DTI ratio can't improve much even as you add income.

The Pro Portfolio Tracker rolls up every property, auto-revalues them against local price data, and flags DSCR risk + equity milestones. At the 1-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.
