Replacement ReservesReserves for replacement: paying for the roof before it fails.

What reserves for replacement are

Reserves for replacement are an annual allowance, often stated per unit, for items that wear out over several years rather than monthly. Examples include roofs, HVAC equipment, water heaters, flooring, appliances and parking lot work.

Setting money aside smooths the cost of these projects. Lenders often require a reserve, and buyers may subtract it from net operating income to get a cleaner view of long-term earnings.

How a reserve is set

Annual reserve = sum of (replacement cost / remaining useful life) for each item

A simple version uses a flat amount per unit per year. A better one lists each major component, its replacement cost and the years it has left, then spreads each cost over those years.

Illustrative figures, not from a real property

A 30-unit building needs a $150,000 roof in 10 years, $90,000 of water heaters over 6 years and $60,000 of parking lot work in 5 years. The annual reserve is $15,000 plus $15,000 plus $12,000, or $42,000, about $1,400 per unit.

Without the reserve, the owner faces a $150,000 bill in one year and a sharp drop in cash flow.

Why reserves matter to owners and buyers

A property with no reserve may look better on paper than it really is. Ask what the reserve is and whether it fits the age and condition of the buildings, and look for it in any pro forma in real estate terms you review.

Reserves are not operating expenses, so they do not count in the operating expense ratio. Our article on reserve accounts in property management covers the risk of underfunding them.

Reserves when you buy or refinance

Lenders often hold part of the reserve in an account they control and release it as work is done. Buyers should ask for the seller's capital spending for the last few years: a building that spent almost nothing on capital items may be saving cash today and passing the bill to the next owner.
