Build-to-Rent Financing: A Broker's Guide to BTR Construction and Permanent Loans

Build-to-rent (BTR) financing is usually two loans in sequence: a construction loan that funds site work and vertical building, then permanent financing once the community has leased up. Senior construction debt commonly covers 55% to 65% of total cost. Purpose-built communities on a single site are generally underwritten like multifamily, which opens the door to bank, debt fund, agency, HUD, life company and CMBS capital at different stages.

What Counts as Build-to-Rent

Lenders separate two things that both get called single-family rental:

• Purpose-built BTR communities. Detached homes, townhomes, duplexes or cottages built on one site, owned by one entity and managed as a single property with shared amenities. This is the product this guide covers.
• Scattered-site single-family rental. Individual houses in different locations held as a portfolio. These are financed by a different, more specialized group of lenders.

Making clear which one you have is the first line of the loan request, because it decides which lenders will look at it.

The Financing Stages

Construction Loans

Banks offer the lowest-cost construction debt, usually with recourse or at least a completion guarantee, and at more conservative leverage. Debt funds lend more, close faster and may be non-recourse apart from standard carve-outs, at a higher rate. Both fund in draws as work is completed. The construction loan glossary entry and the guide to getting construction loans closed cover the mechanics.

Loan sizing starts from loan-to-cost, then is tested against the projected stabilized value and the debt service the finished community will support.

Filling the Gap

A developer who needs more than the senior lender will provide adds mezzanine debt or preferred equity. The senior lender has to consent, and the combined leverage raises the cost of capital, so model the blended rate before recommending it. See mezzanine and preferred equity.

Permanent Financing

Once the community reaches stabilized occupancy, the permanent loan is sized on in-place NOI. Agency lenders have financed BTR communities that meet their multifamily requirements. HUD's 221(d)(4) program can finance new rental construction including detached and townhome formats, with a long processing time in exchange for high leverage and a long fixed term. Banks, life companies and CMBS lenders also lend on stabilized communities.

What Lenders Underwrite

Phasing and Delivery

Unlike an apartment building, a BTR community delivers homes in batches. That is an advantage, since rent starts before the whole project is finished, and a complication, since the lender has to track which homes are complete, leased and generating income. Present a clear phasing schedule with delivery and lease-up assumptions for each phase.

Rent Comparables

Appraisers and lenders may have few true BTR comparables in a market. Expect them to triangulate from nearby apartment rents, individual single-family rentals and any existing BTR communities. A deal that depends on a large premium over apartment rents with no local evidence will be discounted.

Operating Costs

Detached homes have more roofs, more exterior walls and more landscaping per unit than apartments. Lenders look for realistic maintenance, turnover and replacement reserve assumptions, and for a manager who has run this product before.

Sponsor Experience

BTR combines land development, homebuilding and multifamily operations. Lenders want evidence of all three, either in the sponsor or in named partners: a horizontal developer, a builder with capacity, and a property manager with a BTR track record.

Exit Options

Some lenders take comfort that homes on individually platted lots could be sold one at a time if the rental plan underperformed. Others prefer a single parcel because it fits multifamily permanent loan programs more cleanly. Know which structure your deal has and which lenders prefer it.

Key Metrics

• Loan-to-cost for the construction loan.
• Stabilized DSCR, tested at the permanent loan's expected rate. Use the DSCR calculator.
• Stabilized debt yield, which many construction lenders use as an exit test.
• Yield on cost, meaning stabilized NOI divided by total cost, compared with market cap rates.

How Brokers Should Position a BTR Deal

• State up front that it is a single-site, single-owner, professionally managed community.
• Include the site plan, unit mix, phasing schedule and construction budget with contingency.
• Show rent comparables from three sources: apartments, single-family rentals and other BTR.
• Document the experience of the developer, builder and manager separately.
• Present the takeout: which permanent lenders the stabilized community will qualify for, and at what proceeds.

A complete package follows the structure in structuring a deal package. For the wider multifamily lending picture, see the broker's guide to multifamily finance and bridge-to-perm financing.
