Cost overruns on build to rent projects happen more often than most investors expect. Material price increases, permit delays, and unexpected site conditions can all push a project over budget. Understanding how lenders respond to cost overruns helps investors plan ahead, protect their margins, and keep the project on track.
Why Cost Overruns Are Common in Build to Rent #
New construction projects involve many variables, and not all of them can be predicted at the start. Common causes of cost overruns include:
- Increases in material or labor costs after the loan closes.
- Unexpected site conditions such as poor soil, drainage issues, or utility complications.
- Design changes or scope additions during construction.
- Permit delays that extend the project timeline and increase carrying costs.
Even well-planned projects can encounter unexpected expenses. The key is having a plan in place before those situations arise. Because most build to rent loans include interest-only payments during the construction phase, timeline extensions also increase the total interest cost to the borrower.
How the Draw Process Works #
During construction, loan funds are released in draws tied to specific milestones such as foundation, framing, and final completion. Each draw typically requires an inspection to confirm that work has been completed according to the approved plans. This process protects the lender by making sure funds are only released for verified progress.
When cost overruns occur, the draw process can be affected. If actual costs exceed the amounts allocated for a given phase, the borrower may need to cover the difference before the next draw is released.
How Lenders Typically Respond to Cost Overruns #
When a project goes over budget, lenders generally expect the borrower to cover the difference. In most cases, the original loan amount does not increase to accommodate higher costs. Instead, the borrower must bring additional funds to keep the project moving forward.
Lenders may respond to cost overruns by:
- Requiring updated budgets before releasing further draws.
- Requesting proof that the borrower has adequate reserves to complete the project.
- Adjusting the draw schedule to reflect revised costs.
- Pausing construction draws until the borrower demonstrates the ability to cover the shortfall.
The lender’s primary concern is whether the project can still be completed as planned and whether the finished property will support the loan amount.
The Role of Contingency Reserves #
Most lenders expect the construction budget to include a contingency reserve, typically ranging from 5% to 10% of the total construction cost. This reserve serves as a buffer for unexpected expenses.
If the contingency is used up early in the project, it can signal a problem to the lender. Investors who manage their contingency carefully are better positioned to handle surprises without disrupting the draw process.
In some cases, lenders may set a minimum contingency reserve as a condition of the loan. Falling below that threshold could trigger additional requirements or a hold on disbursements.
What Happens When the Budget Exceeds the Approved Loan #
If total project costs exceed what the original loan covers, the borrower is responsible for the difference. This is true regardless of whether the cost increase was expected.
Options at this point may include:
- Contributing additional equity from personal funds.
- Negotiating value engineering to reduce remaining costs.
- Adjusting the scope of work to bring the budget back in line.
In rare situations, a lender may consider a loan modification, but this is not guaranteed and typically involves additional underwriting and documentation.
How Cost Overruns Affect the Permanent Loan #
Cost overruns during construction can also affect the permanent financing phase. If the project costs more than expected, the investor may have less equity in the deal. As a result, the loan-to-value ratio on the permanent loan may be higher than originally planned.
If the LTV exceeds the lender’s maximum threshold, the investor may need to:
- Pay down the loan balance before conversion.
- Accept different permanent loan terms.
- Bring additional funds to close the gap.
For one-time close programs with in-house takeout financing, cost overruns do not change the permanent loan structure, but the borrower still needs to meet the LTV and DSCR requirements at the time of conversion. Planning for this possibility from the start helps investors avoid difficult decisions at the end of the project.
How to Reduce the Risk of Cost Overruns #
While cost overruns cannot always be avoided, investors can take steps to reduce their likelihood. Effective strategies include:
- Working with experienced general contractors who have completed similar projects.
- Getting detailed, fixed-price bids before the loan closes.
- Including a realistic contingency in the construction budget.
- Monitoring the project closely and addressing issues early.
- Avoiding unnecessary scope changes during construction.
In addition, maintaining open communication with the lender throughout the project helps prevent surprises. Lenders prefer to be informed about budget changes early rather than discovering them during a draw request.
Summary #
Cost overruns build rent projects frequently, but how investors handle them makes a significant difference in the outcome. Lenders typically expect borrowers to cover additional costs out of pocket, and a well-managed contingency reserve is essential.
Construction draws are tied to milestones and verified through inspections, so staying on budget at each phase keeps the process moving. By budgeting conservatively, working with experienced contractors, and staying in close contact with the lender, investors can reduce the impact of unexpected expenses and keep their project on track through both the construction and permanent financing phases.
