# Portfolio Units

Portfolio size determines GPR (maximum potential rent) and the operating economies of scale. More units = fixed management cost spread over more income, but also more maintenance and collection complexity.

## Where to find it

Count directly from your property management system (Rentroom, Buildium, or your control spreadsheet if you manage manually) — active units in your portfolio today.

## If it's off

Small portfolios (< 10 units) rarely justify a professionalized operation: management cost consumes the operating margin. The minimum scale for a profitable proptech management operation is typically 30–50 units.

## LATAM Benchmarks

| Status | Range |
|---|---|
| Healthy | > 30 units with occupancy > 90% |
| Alert | 10–30 units (minimum scale) |
| Critical | < 10 units (fixed costs not amortized) |

## How to improve it

In portfolio management, growth through referrals from satisfied owners has near-zero CAC and high asset quality. An active referral system among owners is the most efficient growth strategy.
