The short answer
Three pots pay for it, and all three were filled before you subscribed: the reserve the sponsor funded at closing, operating cash the trustee holds back from the quarterly distribution, and any escrow the lender requires. Rev. Rul. 2004-86 lets the trustee spend that money on normal repair and maintenance, minor non-structural improvements, and work required by law, while barring new contributions and new borrowing. Most DSTs also push routine repairs onto the tenant: in the ruling's own facts the net lessee pays "all insurance, maintenance, ordinary repairs, and utilities". If the pots run dry and the job is bigger than that, the trustee's remaining moves are to sell the property or convert to the springing LLC.
At a glance
| Permitted spending | Normal repair and maintenance, minor non-structural modifications, work required by law |
|---|---|
| Hard bar | No acceptance of additional contributions of assets, including money (Rev. Rul. 2004-86) |
| Second hard bar | No renegotiating the acquisition debt and no new borrowing |
| Reserve investments | Short-term US obligations and bank CDs maturing before the next distribution |
| Distribution rule | All available cash less reserves distributed to owners each quarter |
| Who sets the reserve | The sponsor at closing; the trustee may hold a reasonable reserve thereafter |
| Master lease | The master tenant carries operating costs out of its rent spread, not the trust |
| If reserves fail | Sale of the property, or the Transfer Distribution into the springing LLC |
| Capital call risk to you | None: you cannot be required to contribute more, and cannot volunteer more either |
The ruling's own building pushes repairs to the tenant, which is why net leases dominate the asset list
Read the facts of Rev. Rul. 2004-86 before the prohibitions. The model trust holds one building under a ten-year net lease where the tenant "is to pay all insurance, maintenance, ordinary repairs, and utilities relating to Blackacre". The repair question is answered by the lease, not by the trustee's cheque book.
That design choice is why sponsors favour net-leased and master-leased assets with recent roofs and mechanical systems, and why a heavy-capex building is a harder fit for the structure. Which asset classes appear in DSTs follows from the same constraint.
Where the trustee does have to spend, the ruling permits "only minor non-structural modifications" unless the work is "otherwise required by law". Whether a specific job sits inside that phrase is a facts question the sponsor's tax counsel opines on in the offering documents, so ask to see how that opinion is worded rather than assuming a roof is settled either way.
Where the money sits before the trustee has to make a decision
The reserve is a line in the offering's sources and uses, funded out of your subscription dollars on day one. It is not invested for return: the ruling requires reserve cash to sit in short-term obligations of or guaranteed by the United States and bank certificates of deposit, maturing before the next distribution date and held to maturity, so that nobody can argue the trustee is profiting from market movements.
Three other pools sit alongside it, and a good offering shows all four.
- Lender escrows for taxes, insurance, replacement reserves and, in multi-tenant deals, tenant improvements and leasing commissions.
- Operating cash above the stated distribution, which the trustee may withhold as a reasonable reserve instead of paying out.
- Tenant obligations under the lease, which in an absolute net lease include roof and structure and in a double net lease usually do not.
- Insurance and, where the damage is covered, business interruption proceeds (environmental, insurance and climate risk).
The quarterly distribution rule turns reserve size into a yield decision you make at subscription
The trustee "is required to distribute all available cash less reserves quarterly". That single sentence means reserves and your income compete for the same dollars, permanently.
A sponsor that funds a thicker reserve at closing has less equity buying real estate, and a sponsor that holds back more operating cash pays a lower distribution. So the headline rate on the cover page is partly a statement about how much cushion the deal carries. Compare two offerings on reserve dollars and distribution rate together, never on the rate alone (how reliable DST distributions really are, DST fees and loads).
A master lease moves the capex problem to the master tenant, and your risk with it
In a master-lease DST the trust leases the whole property to a sponsor affiliate, which then deals with the sub-tenants and keeps whatever is left after paying the trust its rent. Operating costs and routine capital work come out of that spread, which is why the structure suits multi-tenant assets the ruling's leasing prohibition would otherwise strand.
The trade is that your rent is now only as good as the master tenant's balance sheet. If a roof eats the spread, the master tenant can stop paying rent to the trust before the trust ever sees the bill. Ask for the master tenant's capitalisation and any guarantee behind it (how DST master leases work, what happens if a master tenant goes bankrupt).
An income shortfall and a capital shortfall are not the same problem
An income shortfall is survivable inside the structure. A tenant stops paying, the reserve covers debt service for a while, the trustee withholds the rest of the cash, and your distribution drops. Nothing about that requires the trust to become something else.
A capital shortfall is different, because the fix needs a lump sum the trust has no lawful way to raise. New equity is barred, new borrowing is barred, and sale proceeds cannot be reinvested, so a large uncovered bill leads straight to a sale or a conversion rather than to a workout.
Watch for the loan's cash management provisions as well. A covenant trip can put the property into a lockbox where the servicer sweeps cash into lender-controlled reserves, which means your distribution stops before the building's problem is solved and the money you thought was your income is funding the repair instead.
Hypothetical: a $900,000 job against a $600,000 reserve
Round numbers, hypothetical. A trust owns a $40,000,000 property, funded a $600,000 reserve at closing and distributes quarterly. In year six the property condition report's projected roof replacement and parking lot work come in at $900,000.
The first $600,000 is straightforward. For the remaining $300,000 the trustee can suspend distributions and accumulate cash, which is legal and unpopular, or the tenant can be obliged to do the work under the lease. What the trustee cannot do is ask the owners for $300,000, borrow it, or take it from a new investor.
The withholding route has a visible price. If the trust pays $1,000,000 a year in distributions, halving them closes the $300,000 gap in about seven months, and you feel it as two or three quarters at half income with no say in the decision.
If neither route closes the gap, the choices narrow to selling the property or triggering the springing LLC, because those are the only two acts left that the structure permits. Confirm how any of this would land on your own return with your CPA or attorney.
Four numbers to ask a sponsor for, in writing, before you subscribe
The offering documents contain all four; the point is to read them against each other rather than one at a time.
- The reserve at closing in dollars, set beside the property condition report's projected capital needs across the whole projected hold.
- The lender's required escrows and whether they are funded up front or swept from cash flow.
- Which party bears roof, structure, HVAC replacement and parking under the lease, and for how long the tenant is bound.
- The age of the roof and the mechanical systems, and the remaining lease term against them (due-diligence questions to ask).
Related questions
Can I be asked for more money after I invest?
No. The trustee is barred from accepting additional contributions of assets, including money, once the offering closes, so a DST cannot make a capital call. The same rule is why it cannot accept your money to save a struggling asset.
If the reserve runs short, do my distributions stop first?
That is usually the first visible sign, because withholding cash as a reasonable reserve is the only self-help the trustee has. Suspended or reduced distributions ahead of a known capital item are worth asking about directly.
Does a triple-net lease mean the trust never pays for a roof?
Not automatically. Absolute net leases typically put roof and structure on the tenant; double net leases usually leave them with the landlord. The answer is in the lease abstract in the offering documents, not in the label.
What about work a city or an ADA order requires?
Rev. Rul. 2004-86 expressly allows modifications "otherwise required by law", so legally mandated work is one of the few categories the trustee can fund without straining the structure.
Do older buildings make this worse?
They concentrate the risk, because the reserve is fixed at closing while the capital need grows with the asset's age. That is one of the items covered in the key risks of DST investments.
Can the trust borrow for a capital item and repay it out of rent?
No. The prohibition on renegotiating the acquisition debt and on new borrowing has no carve-out for small or short-term loans, which is why the reserve at closing is the number that matters.
