Why a hard reserve floor inside a self directed IRA is what keeps a fourplex through a bad four months.

A case worth laying out, because the rule that saves the account is the one most people resent setting up. Say an investor funds a self directed IRA and sets what feels like an over cautious rule: eighteen months of full operating costs in cash inside the account before spending a dollar on a purchase, and never letting it drop below twelve. That rule means buying a cheaper building than they want. Call it $228,000 instead of the $265,000 one they actually like, and a fair amount of sulking about it. Then one spring: a sewer lateral collapses under the driveway, $9,400. Two units turn in the same six weeks, $4,100 in make ready and about $3,800 of lost rent. The insurance renewal jumps 31 percent, another $1,100. Roughly $18,400 of unplanned cash out inside four months. All of it gets paid from the account, on time, with the correct forms, and the owner never once has to weigh writing a personal check, which is not an option inside an IRA anyway. The account bottoms at $11,900 and rebuilds to $19,600. Had they bought the $265,000 building, the IRA hits zero cash sometime in April, and the only levers left are an annual contribution already partly used and a fire sale of a building in the middle of a turn. What to keep: the reserve floor as a hard number rather than a feeling. What to change: set the floor as a percentage of replacement cost rather than months of operating expense, because operating expense does not predict a sewer lateral.
