right of first offer technical
"existing right of first offer"
A right of first offer is a contractual agreement that requires an owner to offer an asset or stake to a designated party before marketing it to others; the holder gets the first chance to negotiate terms directly with the seller. For investors, it matters because it can limit who can buy or set the sale price path—like getting the first invitation to buy a sought-after item before it goes on general sale, protecting potential access or controlling competition.
Base Rent financial
"eight months of Base Rent"
The fixed minimum rent a tenant pays under a lease before any extra charges or variable fees; think of it as the subscription price for a space, separate from add‑ons like utilities, maintenance, or a share of property taxes. Investors watch base rent because it sets the predictable, recurring income stream that determines a property's immediate cash flow and helps value the asset, while extras and escalations affect total returns and risk.
Extension Term technical
"commencing on March 1, 2031"
