Rent Roll Mark-to-Market: Capturing Loss-to-Lease

In multifamily investing, Loss to Lease is the most critical metric for forcing rapid appreciation. It represents the gap between the actual rent currently being collected (contract rent) and the current fair market rate for the open unit.

When a syndicator buys a mismanaged, underpriced apartment complex, closing that gap is the entire business plan. However, realizing this untapped revenue takes intense operational focus, as leases expire on a rolling basis.

To accurately project the financial results of your lease-up strategy, use our Rent Roll Mark-to-Market Projection Calculator.

The Mathematics of the Rent Roll

You cannot simply assume that every tenant will accept a $400 monthly rent increase. If you push rents too aggressively, tenants will vacate, triggering a cascade of negative financial events. An accurate projection must balance two paths:

1. The Renewal Path

Statistically, a percentage of your tenants will choose to renew. For these tenants, you capture partial upside. A 5% increase is highly likely to be accepted because the tenant avoids the massive financial friction of moving (hiring movers, paying new deposits, changing school districts).

• Pros: Zero vacancy days, zero unit turn costs.
• Cons: You do not achieve the absolute maximum market rate.

2. The Turnover Path

The remaining tenants will choose to vacate. This allows you to list the unit at the absolute maximum market rate (often after executing a cosmetic renovation). However, achieving this premium comes with serious costs:

• Turn Cost: Painting, cleaning, and replacing carpets costs real cash.
• Vacancy Downtime: Every day the unit sits empty during renovations and showings is permanent lost revenue.

Creating an Accurate NTM Revenue Projection

If you own a 50-unit complex with average rents $300 below market, projecting your Next 12 Months (NTM) revenue requires balancing these variables. You must subtract the vacancy loss and turn costs from the newly captured market rents.

If the turn costs and vacancy downtime are too high, the project might not break even for two years, destroying your immediate yield.

Our free Rent Roll Mark-to-Market Projection Calculator automates this exact logic. By inputting your unit count, known renewal probabilities, and anticipated turn downtimes, it calculates your precise NTM Effective Revenue and the true net value of your captured loss-to-lease.
