The key idea is how notice affects covenants that run with the land. Real covenants bind successors in interest even if the new owner has no actual notice, because they run with the land through privity of estate and touch/concern the land. Equitable servitudes, on the other hand, bind successors only if the successor has notice of the covenant, and they are typically enforced in equity by an injunction rather than damages. So stating that real covenants do not require notice points to the main distinction in how these two types of covenants operate, making it the best single descriptor of their difference.

The key idea is that a life estate can be transferred during the holder’s lifetime (alienable inter vivos) but cannot be passed by will or to the holder’s heirs. A life estate lasts for the life of the measuring person, and when that life ends, the estate terminates and ownership passes to the future interest holder (the remainderman) or reverts to the grantor. Because the interest ends at death, there’s nothing for heirs to receive by devise or by intestate succession, which is why it’s not devisable or descendible. This combination—transferable during life, but not passable by will or to heirs—fits the description provided.

The main concept is that the implied warranty of habitability makes the landlord responsible for keeping a residential dwelling fit for living. This duty covers essential aspects of the home—structure, plumbing, heating, electrical, sanitation, and overall safety—and requires the landlord to repair serious defects that affect health and the ability to inhabit the property. The warranty generally applies to most residential leases, including single-family homes and rentals in multi-unit buildings, and it doesn’t simply vanish because a lease says otherwise; in many places some waivers are limited or ineffective, especially for fundamental needs. Because of this duty, tenants can obtain remedies such as rent abatements, damages, or lease termination if the landlord fails to fix major problems. The warranty does not hinge on the tenant’s prior notice as a condition of liability; while notice often starts the process of remedies, the landlord’s obligation to repair does not depend on demanding a notice first.

The key idea is how a liquidated damages clause is treated in real estate contracts. Earnest money can serve as liquidated damages when the amount set in the contract is a reasonable forecast of the damages the seller would suffer if the buyer breaches. In other words, it’s intended to be a genuine pre-estimate of harm, not a penalty. If the amount is so large or arbitrary that it Functions as punishment rather than a fair estimate of actual damages, a court will consider it a penalty and likely refuse to enforce it. So, the best answer says the earnest money may be liquidated damages if the amount is reasonable; otherwise it is a penalty. This captures the essential distinction between a legitimate pre-estimate of damages and an unenforceable penalty. Why the other ideas aren’t correct: it isn’t automatic that earnest money is always liquidated damages, and it isn’t never liquidated damages. Earnest money can be used as a liquidated-damages remedy when the clause meets the reasonableness standard, and it can be relevant in land contracts as part of the deal.
