Private lending is frequently described as a secured position: the loan is backed by real estate, supported by a personal guarantee, and written at a conservative loan-to-value. If the borrower defaults, the collateral covers the balance.
The structure is sound. The assumption embedded in it is not.
Collateral protects you against a decline in borrower performance. It does not protect you against an error in what the collateral is worth, against a project that consumes more capital than it can produce, or against a foreclosure process that costs more and takes longer than the spread you underwrote. Lenders who lose capital rarely lost it because the loan was unsecured. They lost it because the security was worth less than the file said.
The valuation is the loan
Every protective term in a private loan is expressed as a percentage of value. A 65% LTV is only conservative if the value input is accurate. If the after-repair value is overstated by 25%, a 65% LTV is actually 87%, and the entire margin the structure was supposed to provide has been consumed before the loan funds.
This is the single largest source of loss in private lending, and it is systematically underweighted because the number arrives in a document that looks authoritative.
The appraisal supporting a construction loan is a projection. It states what the property will be worth if the described renovation is completed to the described standard in the described market. Each of those conditions can fail, and the appraisal does not price the probability that they do.
Lenders who rely on the borrower's appraisal are relying on a valuation commissioned by the party who benefits from a high number. That is not a comment on appraiser integrity. It is a comment on who selected the appraiser, who defined the scope, and whose renovation description the valuation is conditioned on.
The construction budget determines whether the collateral gets built
A loan against a partially renovated property is a loan against a distressed asset with a limited buyer pool. The value that supports the loan only exists on completion.
If the construction budget is understated by 30% — which is routine in borrower-prepared budgets — the borrower runs out of capital before the work is finished. At that point the lender's options are all expensive: fund the overage and increase exposure, foreclose on an unfinished property worth substantially less than the completed value, or negotiate a workout with a borrower who is out of money.
Reviewing the construction budget is not a courtesy to the borrower. It is a direct assessment of whether your collateral will exist in the form your loan assumes.
The specific things to check: whether the scope in the budget matches the scope in the appraisal, whether contingency is present and adequate, whether permits and inspection costs appear, whether holding costs during construction are funded, and whether the per-square-foot pricing is plausible for the market.
Contractor risk is lender risk
The lender is not a party to the construction contract, which creates a tendency to treat contractor selection as the borrower's concern.
It is not. If the general contractor is unlicensed, uninsured, underqualified, or dishonest, the project fails and the collateral does not get built. The borrower's inexperience in vetting contractors becomes the lender's loss.
Verify the contractor directly: license status pulled from the state board, insurance confirmed with the carrier, prior projects of comparable scope and complexity, and a litigation and lien search under all associated entities.
A borrower who cannot produce a qualified contractor has not yet demonstrated the project is executable.
Draws are where funds actually leave
The draw process is the lender's primary ongoing control, and it is frequently the weakest part of the file.
Funds advanced ahead of completed work are unsecured. If a draw is released for work that has not been performed and the borrower or contractor then fails, that money is gone and the remaining collateral value is unchanged.
The controls are straightforward: third-party inspection before every disbursement, funding against verified completion rather than calendar or borrower representation, no advances for materials not delivered to the site, lien waivers collected against every payment, and retainage held until final completion.
Lenders relax these controls under time pressure, on repeat borrowers, or when the borrower is persuasive about a cash flow gap. The relaxation is where the loss occurs.
Liquidity is what covers the gaps
Every construction project encounters cost overruns and delays. The question is not whether they occur but whether the borrower can absorb them.
A borrower with no liquidity beyond the down payment has no capacity to fund an overage, carry an extended timeline, or cover a shortfall between the loan proceeds and the actual cost to complete. The first material problem becomes a default.
Verify liquidity independently. Bank statements, not stated balances. Confirm the source of the down payment. Confirm that the reserves are actually reserves rather than funds already committed to another project. Borrowers running multiple simultaneous deals frequently show the same liquidity to several lenders.
The exit determines whether you are repaid
The loan is repaid from the exit — a sale or a refinance. A file that does not stress test the exit has not underwritten the repayment.
If the exit is a sale, the questions are absorption rate, days on market for comparable completed properties, and what the sale nets after costs at a price 10% below the projection.
If the exit is a refinance, the questions are whether the borrower will qualify at the projected value, whether the debt service coverage works at plausible rates rather than current rates, and whether the rental projections supporting the refinance reflect actual signed leases in the market.
An exit that only functions in the base case is not an exit. It is an assumption.
Position and documentation
Two structural exposures that produce losses independent of deal quality:
Junior positions. A second-position lender behind a senior loan is exposed to the entire senior balance before recovering anything. In a value decline or a foreclosure with meaningful costs, junior positions are frequently wiped out entirely while the senior recovers in full. Price and size the position accordingly, or do not take it.
Loan documents. Missing or defective provisions surface only in default, when they cannot be corrected. Confirm the security instrument is properly recorded in first position, that the title policy names the correct insured for the correct amount, that the guarantee is enforceable against a party with assets, that default and remedy provisions are complete, and that assignment and transfer restrictions are present.
The foreclosure math
Underwriting frequently assumes that foreclosure makes the lender whole. Run the actual numbers before relying on it.
Foreclosure takes months to more than a year depending on jurisdiction. During that period you are advancing property taxes, insurance, and often utilities and security. You are incurring legal costs. You may take possession of a partially completed property requiring capital to make marketable, and you sell it into whatever market exists at that time rather than the market you underwrote.
Recovery net of all of that is materially below the collateral value in the file. A position that appears adequately protected at 65% LTV against a projected completed value can be underwater against actual net recovery on an unfinished property in a soft market.
The common structure
These failures share a characteristic: the lender relied on documents produced by parties whose compensation depended on the loan funding. The borrower prepared the budget. The borrower's appraiser produced the valuation. The borrower selected the contractor. The broker assembled the package.
Every input was supplied by someone with an interest in a yes.
Independent underwriting means reproducing the critical inputs — valuation, construction budget, contractor qualification, exit feasibility — from sources with no stake in whether the loan closes. The cost of that review is a small fraction of a single loss, and it is the only part of the file that is genuinely working for the lender.
