When a loan is “secured by real estate,” it means the lender records a lien against the property — a legal claim that gives them the right to be repaid from that asset. Lien position is the order in which lenders get paid if the property is ever sold: a first lien is paid first, a second lien is paid after it. For a business that owns real estate, understanding lien position is the key to knowing what you can borrow, from whom, and on what terms.
First lien: the senior claim. A first-lien loan (like most primary mortgages) sits at the front of the line. Because it carries the least risk to the lender, it's usually the largest and lowest-cost financing against a property. If you own real estate free and clear, a new loan against it can be a first lien.
Second lien: borrowing behind a loan you want to keep. If you already have a first mortgage — especially a low-rate one worth keeping — a second-lien loan lets you raise capital against the remaining equity without refinancing the first. It sits behind the first in priority, so it's sized to the combined exposure on the property.
Cross-collateralization: more than one property. Sometimes a single property doesn't fully cover the capital a business needs. Cross-collateralizing — securing one loan with two or more properties — can bridge that gap. It's a structure many banks decline for complexity rather than credit, and it's a core part of what private lenders underwrite.
Why it matters for you: lien position drives how much you can borrow and how the loan is priced. A lender who understands your whole picture — the property, any existing liens, and your plan — can structure around it. At BuildUp, we lend in first or second position and cross-collateralize when it makes sense, secured by commercial or residential real estate.
