An underfunded RV park reserve fund is the silent deal killer that most buyers never see coming. The deal looked solid. The numbers worked. Due diligence got done. The deal closed. And then somewhere in the first twelve to eighteen months the cash position started tightening in ways that were not in the projections
In most of those situations, the deal was not bad. The reserve fund was.
What a reserve fund actually is
A reserve fund is not a savings account you contribute to when things are going well. It is a dedicated, non-negotiable capital account funded from day one of ownership, sized to absorb the normal variability of running an operating business on a seasonal cash flow cycle.
Most buyers understand the concept in theory. The problem is in the execution. The reserve gets underfunded at close because the down payment stretched capital further than planned. Or it gets raided in month three because a piece of equipment failed and the operating account was already running thin. Or it never gets funded at all because the buyer assumed the first season’s revenue would build it up organically.
None of those approaches survive contact with reality.
The three things your RV park reserve fund has to cover
When you are sizing your reserve, you are not just planning for one type of risk. You are planning for three that can hit simultaneously.
The first is capital expenditure. Equipment fails. Infrastructure ages. The septic pump that was fine during due diligence develops a problem in month six. A reserve fund that is not sized for capital events is not a reserve fund. It is a checking account with a different name.
The second is operating cash flow gaps. RV parks are seasonal businesses. If your park generates most of its revenue between May and September, your reserve fund is what carries you through October, November, February, and March. The fixed costs do not stop because the guests do. Insurance, loan payments, utilities, any year-round staffing, and basic maintenance continue regardless of occupancy. If you do not have reserves sized to cover that gap comfortably, you will be making decisions under pressure during every slow season you own the park.
The third is the unexpected. Not the dramatic unexpected, just the normal unexpected that every operating business experiences. A key employee leaves. A major OTA platform changes its algorithm and your bookings drop for sixty days while you adjust. A regional weather event cancels a peak weekend. These are not disasters. They are the cost of operating a hospitality business. Your reserve fund is what keeps them from becoming crises.
What underfunded reserves actually look like in practice
When a buyer closes without adequate reserves, the signs show up fast. Deferred maintenance starts accumulating almost immediately because every dollar of operating cash is needed for operations. Capital projects get pushed to next season, and then the season after that. Reviews start to reflect it before the financials do.
The pressure compounds. A slow month creates a cash shortfall. The shortfall gets covered by skipping the reserve contribution. The next unexpected expense hits a reserve account that is already depleted. The buyer is now making every financial decision reactively instead of proactively, which is exactly the operating posture the previous owner was in when they decided to sell.
I have seen buyers in this position within six months of closing on deals that were genuinely good acquisitions. The park was fine. The capital structure was not.
What an adequate reserve actually looks like
There is no universal number, but there are reasonable benchmarks. At minimum, you should close with three to six months of total operating expenses in reserve, separate from your down payment and closing costs. On top of that, any identified CapEx from due diligence should be fully funded before you close, not planned to be funded from operating cash flow after the fact.
If your park has meaningful seasonality, size the reserve to cover your worst-case slow season cash flow gap with margin to spare. Model that number at the monthly level before you finalize your offer, not after you close.
A good rule of thumb for ongoing reserve contributions is a minimum of five percent of gross revenue deposited monthly into a dedicated capital reserve account, treated as a non-negotiable operating expense rather than discretionary savings. That account does not get touched for operating expenses. It exists for capital events and genuine emergencies only.
The conversation most buyers do not have before they close
The reserve fund conversation almost never happens with the broker. It rarely happens with the lender, whose job is to get the loan closed, not to stress test your post-close capital position. It sometimes happens with a CPA, if the buyer has one engaged early enough.
What it requires is someone looking at the full capital picture before you commit: down payment, closing costs, identified CapEx, operating reserves, and slow season cash flow requirements, all on one page, sized against the actual cash you have available to deploy.
If that number does not work, the deal does not work, regardless of what the pro forma says.
The buyers who close well-capitalized make decisions from a position of strength for the first two years of ownership. The buyers who close thin spend those same two years managing cash flow anxiety instead of building a business.
The park is the same either way. The experience is not.
