How much should you put down?

The standard argument for maximum leverage is straightforward. Less cash per deal means more deals, and more deals means more appreciation, more depreciation and more equity build across a larger asset base.

The argument is correct in a rising market with stable income. It is the argument that produces the largest portfolios and, in downturns, the largest failures.

What each level of leverage actually buys

Low leverage, say fifty percent. Strong coverage, substantial cushion, ability to survive extended vacancy or a bad capital year, and generally lower returns in good conditions.

You also retain the option to borrow later, which is worth something precisely when credit tightens.

Moderate leverage, sixty-five to seventy-five percent. Where most institutional real estate operates. Meaningful return enhancement with coverage that survives ordinary bad years.

High leverage, eighty percent and above. Available on residential investor loans and via various creative structures. Amplified returns, minimal cushion, and complete dependence on things going roughly as planned.

The arithmetic of a bad year at each level

Take a property with $50,000 of NOI, valued at $700,000.

At fifty percent leverage, a $350,000 loan at seven percent over thirty years costs about $27,900 a year. Coverage of 1.79. NOI can fall forty-four percent before the property stops covering debt.

At seventy-five percent, a $525,000 loan costs about $41,900. Coverage of 1.19. NOI can fall sixteen percent.

At eighty-five percent, $595,000 costs about $47,500. Coverage of 1.05. NOI can fall five percent.

Five percent is a single unit vacant for two months in a small building. It is one insurance renewal in a hard market. It is one eviction.

The high-leverage investor is not running a more aggressive strategy. They are running a strategy that requires nothing to go wrong.

What actually goes wrong

Worth listing, because the base case never includes any of it.

An extended vacancy. A tenant who stops paying and takes months to remove. A major capital item failing early. An insurance premium doubling. A property tax reassessment. A special assessment. A regulatory change affecting rents. A local employer closing. A structural problem discovered after purchase.

Any one of these is survivable with cushion. Two at once, without cushion, is not.

The reserve question

More important than the down payment percentage, and almost always neglected.

A reasonable reserve is enough to cover debt service and operating expenses through a period of no income, plus the cost of a major capital replacement.

For a single small property, that is frequently in the range of six months of full carrying costs plus the cost of the most expensive system likely to fail.

An investor with seventy-five percent leverage and twelve months of reserves is in a stronger position than one with sixty percent leverage and none.

The mistake is treating the down payment as the total capital requirement and closing with an empty account.

The portfolio view

Leverage decisions should be made at the portfolio level, not property by property.

Three properties at seventy-five percent, cross-collateralized or simply owned by the same person with the same personal guarantees, do not diversify anything if they are in the same submarket and the submarket softens.

Correlated risk taken three times is one risk taken at scale.

A workable framework

Start from the coverage ratio you want, not the leverage percentage. Decide what NOI decline you want to survive, and let that determine the loan size.

For most private investors, a coverage ratio of 1.3 or better on stabilized property is a reasonable floor, with more required in volatile submarkets, in properties with concentrated tenancy, or in older buildings with deferred capital.

Then fund reserves before considering the deal financed.

Then, if there is capital left and the deal still makes sense, proceed.

The uncomfortable conclusion

This framework produces fewer deals, smaller portfolios and lower returns in good conditions.

It also produces a business that is still operating after a bad three years, which is the only condition under which the long-run compounding that makes real estate attractive actually happens.

The investors who lost everything in past cycles were rarely wrong about the properties. They were wrong about how much room they had.
