Finance a portfolio and the first structural fork appears immediately: one loan per asset, or one blanket loan across all of them. The blanket usually wins on terms, one origination, one lender relationship, better pricing on the larger balance, cross-collateralized strength the lender rewards. What the blanket costs is flexibility, and the entire cost is concentrated in one negotiated schedule that buyers routinely treat as boilerplate: the release prices.
The mechanics in one paragraph. Under a blanket loan, selling any single property requires releasing it from the lender's lien, and the loan documents specify the price of that release, typically the asset's allocated loan amount plus a premium, so the loan balance falls faster than proportionally with each sale. The premium is the lender maintaining their coverage as the collateral pool shrinks, which is rational from their chair. From yours, it means every early sale pays a toll, and the toll schedule was set on the day you closed the loan, in a negotiation most buyers spent on the interest rate instead.
Underwrite the release schedule as what it is: a price list for your future options. The scenario that exposes it is the partial exit, and it deserves to be run before closing on every blanket deal: asset two gets an unsolicited offer in year three, the release price is allocated loan plus the premium, and the question is whether the sale still pencils after the toll, or whether the remaining portfolio can even support its debt once the strongest asset leaves. That second question is the one that surprises people, because releases interact: the properties that sell first are usually the best ones, and a release schedule that lets the strong assets walk at modest premiums can leave the tail of the portfolio over-levered against the loan that remains. Lenders model this. Borrowers should model it first.
Allocation is the quieter negotiation inside the negotiation. The loan amount allocated to each asset drives its release price, so allocation is not bookkeeping, it is pre-pricing your exits: load the allocation onto assets you intend to hold and the ones you might sell walk cheaper. Sellers of flexibility, which is what lenders are in this clause, respond to buyers who arrive knowing exactly which flexibility they intend to use.
This is precisely the machinery Portfolio Deal Underwriting in PropCalc™ carries natively: blanket debt with per-asset allocations and release prices, so a modeled early sale pays its real toll and the surviving portfolio shows its real coverage. The blanket loan is frequently the right answer. The release schedule is where you find out what the answer costs, and the time to find out is while it is still a draft.
