Property Management: Comparison of Three Strategies
The charts below show how Genstar Property Management Advisory is the most cost effective solution, while also reducing your risk as an owner. These comparisons lay out the total annual cost and operational tradeoffs of each management approach at three portfolio sizes, using Greater Boston/Southern New Hampshire market assumptions.
Twenty-Five Unit Portfolio
Takeaway: At 25 units, in-house doesn't yet mean a real property manager — it's part-time clerical and property management support while the owner still carries the operational load and risks.
Fifty Unit Portfolio
Takeaway: 50 units is the pressure point for self-management — 24+ hrs/week is no longer sustainable alongside anything else. A part-time in-house PM starts to look slightly comparable in cost to third-party, but carries single-point-of-failure risk that a firm's staff depth avoids.
One Hundred Unit Portfolio
Takeaway: At 100 units, self-management is no longer realistic without additional hires — the hours required exceed a full-time job on their own. The real comparison is full-time in-house PM vs. third-party: in-house costs less on the fee comparison but carries turnover, HR, and coverage risk that a firm absorbs.
Bottom Line
The crossover isn't really about unit count in isolation — it's about when the fully-loaded cost of building your own team (or the hidden cost of your own time) starts to exceed a management fee that already includes systems, redundancy, and expertise. For most owners in the 25-100 unit range, that crossover favors third-party management once owner time and turnover risk are priced in honestly.
Assumptions
Average gross rent of $2,200/unit/month; third-party management fee of 4% - 5% of collected rent depending on portfolio size; owner time valued at $75/hr. In-house property manager rate of $75/hour, bookkeeper rate of $50/hr. 6 hours each at 25 units, 12 hours each at 50 units. For 100 units, 45 hours/week for full-time property manager, 24 hours/week for admin/bookkeeper. Actual figures will vary by market, unit mix, and specific staffing arrangement.
