Replacement reserves

Also called Reserves for replacement, Capital reserves.

Replacement reserves are an annual allowance set aside for the periodic replacement of building components that wear out: roofs, HVAC, appliances, parking surfaces, elevators. They smooth lumpy capital spending into a level annual charge.

How it works

Physical components fail on their own schedule and not evenly. A reserve converts that into an annual number so that a single year's cash flow is not distorted by a roof, and so that a valuation is not built on a year that happened to have no major replacements in it.

Whether the charge sits above or below the NOI line is the contested part, and it is worth being blunt about why. Appraisers and lenders normally deduct it above the line, because they are valuing a building that will need a roof. Seller pro formas frequently place it below the line or omit it, because at a 5 percent cap rate every dollar above the line costs twenty dollars of asking price. Both parties know this. The number is small and the argument is not.

Conventional allowances are $250 to $350 a unit a year for stabilised multifamily, more for older stock, and roughly $0.15 to $0.25 a square foot for office and industrial, with tenant improvements and leasing commissions handled separately on top. A lender will often impose its own figure regardless of what the model says, and may escrow it monthly.

Worked example

Above the line or below it

220 units at $250 a unit a year, $55,900,000 under contract, cap rate 5.40 percent. Lender terms as on the sample deal: 65 percent LTV, 1.25x minimum DSCR on the 7.467 percent amortising constant, 8.25 percent debt yield floor.

Annual reserve$55,000
NOI excluding reserves$3,020,000
NOI including reserves$2,965,000
Implied value excluding reserves$55,925,926
Implied value including reserves$54,907,407
Loan proceeds excluding reservesthe 1.25x DSCR test binds$32,356,442
Loan proceeds including reservesthe 1.25x DSCR test binds here too$31,767,169
Value and loan proceeds both fall$1,018,519 of value, $589,273 of debt

A $55,000 line item moves value by about a million dollars and proceeds by more than half a million, because coverage is the binding test on both sides of the reserve. Underwriting the reserve below the line while the lender underwrites it above the line is how an equity gap appears late, and if the appraiser deducts it too, the LTV test tightens on top.

The common mistake

Using the reserve as the capital budget

A reserve is an ongoing allowance for recurring component replacement. It is not the renovation budget, not the deferred maintenance identified in the property condition report, and not the money for a repositioning. Those are funded capital, sized from a scope of work and shown in the sources and uses at closing. Merging them produces a model where a $4 million renovation is somehow being paid for out of $55,000 a year, and the error usually surfaces as an unexplained cash shortfall in year two.
