What is the difference between Single-Family Rental (SFR) and Build-to-Rent (BTR)?

Single-Family Rental (SFR) is the broad category — any rental of detached single-family homes. Build-to-Rent (BTR) is the subset of purpose-built, single-developer communities of detached or attached single-family homes designed from inception for rental rather than ownership. Scattered-site SFR (Invitation Homes INVH model) is acquired one-by-one in target markets; BTR is greenfield-developed neighborhoods (typically 100-300 homes) with shared amenity centers.

How does SFR compare to multifamily?

SFR has higher unit revenue (per-home rent typically $2,000-3,500+ vs $1,500-2,200 typical multifamily), longer lease lengths (renewal rates 70-75% vs 50-60% multifamily), and lower turnover cost (more stable households). Operating expense ratio runs higher (35-45% vs 30-40% multifamily) due to per-home maintenance + landscaping. NOI margins typically 55-60% vs 60-65% institutional multifamily. SFR holding periods are longer (6-9 years vs 4-7 multifamily).

Which REITs invest in single-family rental?

Invitation Homes (INVH, ~$24B mkt cap) is the largest with ~80,000 homes across major Sun Belt markets. American Homes 4 Rent (AMH, ~$14B mkt cap) holds ~60,000 homes. Tricon Residential (TCN) was taken private by Blackstone Q1 2024 for $3.5B. Major private institutional SFR owners: Pretium Partners (~$50B AUM), Progress Residential (~85,000 homes), Main Street Renewal, FirstKey Homes. Adjacent public REITs: Equity LifeStyle Properties (ELS) and Sun Communities (SUI) own manufactured housing communities — different asset class but similar single-family rental dynamics.

Single-Family Rental KPIs.

Single-Family Rental (SFR) is a maturing institutional asset class encompassing scattered-site single-family homes (acquired during 2010-2015 distressed cycle) and Build-to-Rent (BTR) communities (purpose-built single-family rental neighborhoods). Performance is measured in per-house P&L aggregated to portfolio (NOI, occupancy, turn cost, lease length), hold period (longer than multifamily, 6-9 years vs 4-7), and renewal rates (70-75% — lower than multifamily 50-60% due to family stability). The institutional sector emerged 2012 (Blackstone Invitation Homes) and now exceeds $100B AUM. Comparable REITs: INVH (Invitation Homes — largest, ~80,000 homes), AMH (American Homes 4 Rent — ~60,000 homes). Tricon Residential was taken private by Blackstone Q1 2024 for $3.5B. BTR developers / operators: Pretium (private), AHV Communities, Lennar Multi-Family.

NOI: Total revenue minus operating expenses (excludes financing and capital costs). The primary measure of property-level profitability.
Cap Rate: Net Operating Income divided by current property value. Expresses unleveraged annual yield as a percentage.
DSCR: Net Operating Income divided by total annual debt service. Lender-required cushion measure; below 1.0 means NOI cannot cover debt.
LTV: Loan amount divided by property value. Lower LTV = lower lender risk.
OER: Operating expenses divided by gross revenue. Lower is better, but varies by property type (hotels run higher than triple-net retail).
GRM: Property value divided by gross annual rental income. Quick valuation shortcut; less precise than cap rate.
IRR: Annualized return on investment accounting for time value of money across the full hold period.
CoC: Pre-tax annual cash flow divided by total cash invested. Measures the cash yield, not total return.
DCF: Valuation method that projects future cash flows and discounts them to present value at a chosen rate.
TTM: A rolling sum of the most recent 12 months. Smooths seasonality for KPI comparisons.
EGI: Gross potential rent minus vacancy and credit losses, plus other income (parking, laundry, fees).
LTL: Difference between market rent and current contract rent across the rent roll. Measures lease-up opportunity on turnover.
Renewal: Percentage of expiring leases that renew. Higher renewal rates indicate retention; turnover costs avoided.
Concessions: Concessions (free months, discounts) divided by gross rent. Measures pricing pressure.
RUBS: Method of allocating master-metered utility costs to residents based on unit area or occupant count.
