Completing a Purchase Without Breaking Your Investment Strategy
A property purchase arrives with a date attached. Completion is fixed by contract, the deposit is already committed, and the calendar belongs to the transaction, not to the buyer. An investment strategy has no such date. It was built to run for years, through full market cycles, on the explicit assumption that nothing external would force its hand. The moment a purchase is funded by selling part of the portfolio, those two calendars collide, and it is always the strategy that gives way.
This piece is about keeping them apart. Not because selling is always wrong, but because selling on a schedule set by a property transaction is a decision taken under the wrong constraint. There is a financing instrument built for exactly this situation, and it deserves to be examined not as a credit product but as what it really is: a way of completing a purchase without asking the portfolio’s permission. The instrument is Lombard credit, and what matters here is not its mechanics but its place in the strategy: what it protects, what it risks, and how it should be sized.
The purchase sets the date. The market does not.
Every acquisition has its own rhythm. An offer is accepted, a deposit is paid, due diligence runs, and a completion date is written into the contract. From that point the buyer’s obligations are fixed in time. The funds must be available on a specific day, in a specific account, whatever markets happen to be doing that week. Nothing about the property transaction is interested in whether this is a good moment to sell securities.
A portfolio works on the opposite principle. Positions are held because of a view on their value over years, not because of what they can be converted into on a given Thursday. Diversification, income and compounding all assume continuity. None of them assumes that a notary’s diary will decide when part of the portfolio becomes cash, yet that is precisely what happens when a completion date starts driving investment decisions.
When the purchase is funded by selling, the transaction calendar overrides the investment calendar. If markets are weak in the weeks before completion, the investor sells into that weakness anyway, because the date does not move. Positions accumulated patiently over years are unwound in days to meet a deadline that has nothing to do with their prospects. The sale is executed at whatever level the market offers on the day the money is needed.
There is a name for someone who sells because they must rather than because they choose to: a forced seller. A large part of what a portfolio strategy exists to do is make sure its owner is never one. Funding an acquisition through liquidation makes the owner exactly that, voluntarily, and on the one variable where forced selling hurts most, which is timing. The price of that position is set by the calendar, and calendars negotiate with no one.
What a sale takes out of the strategy
The first cost is crystallisation. Gains that existed on paper become taxable on the day of sale, and the moment of taxation is chosen by the property calendar rather than by any tax planning. What could have been deferred or timed is settled when the completion date says so. The size of that cost depends on jurisdiction and personal circumstances, which is why it belongs in a specific analysis rather than a general article, but the mechanism is universal.
The second cost is income. A portfolio that pays dividends and interest stops paying them on whatever portion is sold. If the property being acquired is an investment asset, its rent may eventually replace part of that income, but the replacement is neither immediate nor equivalent, and the comparison between the two streams deserves to be made explicitly rather than assumed in the buyer’s favour.
The third cost is distortion. A partial sale is never neutral. Selling the winners crystallises the largest gains. Selling the losers locks in exactly the losses the strategy expected to recover. Selling proportionally across everything disturbs allocations that were set deliberately. Whichever route is chosen, the portfolio that remains is not a smaller version of the old one. It is a different portfolio, reshaped by a real estate transaction that had no view on any of its holdings.
The fourth cost is the re-entry problem, and it is the one investors underestimate most. The plan is usually to rebuild the position once the purchase has settled. By then the market has moved, the entry point looks uncomfortable, and the rebuild waits for a better moment that keeps not arriving. An interruption that was supposed to last months quietly becomes permanent. Anyone who has tried to re-enter a market they exited knows that the second decision is harder than the first.
Borrowing against the portfolio instead
A Lombard facility approaches the problem from the other side. Instead of converting investments into cash, the portfolio is pledged as collateral for a credit line, and the line funds the purchase. The securities remain invested and continue to generate dividends and interest throughout. The strategy is not interrupted. It is encumbered, which is a different and far more reversible condition: a pledge ends when the debt does, while a sale is final.
The lender, typically a private banking institution, does not lend against the portfolio’s full value. It applies an advance rate that reflects the quality of the collateral: how liquid the positions are, how diversified, how volatile, and in which currencies they are held. A concentrated holding in a single security is treated very differently from a diversified portfolio of liquid instruments. The rate is set against the specific portfolio in front of the bank, not taken from a brochure.
The bank’s questions do not stop at the securities. It will want the purpose of the credit, the shape of the borrower’s structure if the portfolio is held through a company, and a repayment plan it can read. None of that is onerous for an investor whose affairs are in order, but it takes time, and the time is only available if the conversation starts early. A facility discussed while the acquisition is still probable rather than contracted is a negotiation. The same facility requested days before completion is a favour, and favours have terms.
In one transaction, an investor holding a EUR 3M diversified portfolio with a Luxembourg institution financed a EUR 1.5M Spanish acquisition through a Lombard line, with the bank applying a 60 per cent advance rate that produced a maximum capacity of EUR 1.8M. The portfolio remained fully invested and kept generating dividends and interest, and the repayment plan was built on rental income and future distributions rather than on an eventual sale of securities.
Notice what that kind of arrangement preserves. The purchase completes on its contractual date, funded in full. The investment strategy is never consulted, because it no longer has anything to concede. The two calendars, transactional and strategic, run in parallel instead of colliding, and the only change on the investment side is a pledge that is designed to be temporary.
A portfolio decision, not a credit decision
The natural way to evaluate a Lombard line is as a credit product: what it costs, how much is available, how quickly it can be arranged. That framing misses the point. For a liquid, diversified portfolio held with a serious institution, availability is rarely the real issue. The real question is whether the strategy should be interrupted at all, and that is a question about the portfolio, not about the loan.
Framed that way, the comparison changes shape. The cost of the facility is weighed not against zero but against everything the sale would remove: the crystallised gains, the interrupted income, the distorted allocation, the re-entry risk. Sometimes the comparison still favours selling, particularly where positions were due to be exited anyway or the portfolio no longer reflects any strategy worth protecting. The point is not that borrowing always wins. The point is that the comparison deserves to be made with the full cost of selling on the table, and it rarely is.
The decision also has to include the risk that comes with the instrument. A pledged portfolio is marked to market. If its value falls significantly, the bank will ask for additional collateral or partial repayment. That risk is managed the way every portfolio risk is managed: through sizing. A line drawn well below its maximum capacity leaves headroom for markets to fall without triggering anything. A line drawn to the ceiling has no cushion, and turns ordinary volatility into an event.
Finally, the facility needs a repayment source that does not depend on selling the collateral, otherwise the sale has merely been postponed rather than avoided. Rental income from the acquired asset, distributions from operating companies, planned liquidity events: any of these can anchor an amortisation plan. A Lombard line with a documented repayment path is a financing. A Lombard line without one is a market bet with interest attached.
What goes wrong in practice is rarely the instrument. It is the order of decisions. The line is sized to the purchase instead of to the portfolio, drawn to the ceiling because the property cost what it cost, and left without a repayment plan because the completion date absorbed everyone’s attention. Each of those choices is individually understandable, and collectively they convert a strategic tool into a fragile one. The corrective is equally unglamorous: decide the maximum acceptable draw as a portfolio matter first, and let that figure discipline the property budget, not the other way round.
Keeping the two calendars apart, deliberately
None of this happens by improvisation in the week before completion. The lender will want to understand the portfolio, the borrower’s structure, the purpose of the funds and the plan for repayment, and assembling that file takes preparation. The time to start is when the acquisition becomes probable, not when the completion date is already fixed and close. A structure arranged calmly is negotiated. A structure arranged urgently is accepted.
Preparation also protects the strategy on the other side of the pledge. Deciding in advance how large the line should be, relative to its maximum capacity, is what keeps the margin call risk theoretical. Deciding in advance what repays it is what keeps the pledge temporary. Both decisions belong inside the investor’s overall allocation thinking, alongside every other exposure the portfolio carries, rather than inside the file of a single property.
It helps to treat the facility’s afterlife as part of the design. A pledge that was meant to be temporary stays temporary only if the repayments actually happen, so the plan should name its sources and its dates, and someone should own it. When rents arrive, part of them reduces the line rather than resting in an account. When a distribution is paid, the same. A strategy protected at completion can still be eroded afterwards by a line that never shrinks, and the difference between the two outcomes is administration, not markets.
The conclusion is not that portfolios should never be sold. It is that a property transaction is the wrong reason and the wrong clock. A purchase will always fix its own date. A strategy should never inherit it. Keeping the two apart is precisely what a well-sized, well-prepared Lombard structure does, and the investors who use it best are the ones who treat it as part of the strategy rather than as an exception to it.
