If you are the owner, yes.
In the case of a conventional life estate the life estate holder and the remainderman must both execute the deed if they agree to sell the property. See related question link.
A person with a remainder interest can sell their interest. However, the property remains subject to the life estate until the life tenant dies or releases their life estate in writing.
The remainderman can sell their interest as a remainderman in the property subject to the life estate. The life tenant has the right to the use and possession of the property for life.
Generally a life estate entitles the beneficiary to all property rights except the right to sell or otherwise transfer the fee in the property. It cannot be defeated by the conveyance of the property. If the house was sold the buyer would acquire it subject to the life estate. If the life estate holder desires to relinquish the life estate in order to sell the property then she/he may join in the deed of conveyance and the life estate will end.
The person who owns the fee receives the proceeds from the sale. The life estate holder only has the right to use the property for life. If they relinquish their life estate the owner of the property can then sell it free and clear of the life estate.
A life estate grants the right to the USE and POSSESSION of real property for life. The holder of a life estate is not the owner of the property. Therefore, you cannot take possession of the property and sell it if you have a judgment lien only against the life estate holder. If you have a judgment lien against the owner of property that is SUBJECT TO the life estate of someone else, the property would remain subject to the life estate if you took possession and tried to sell it. You would need to find a buyer who is willing to honor the existing life estate.
No. A life estate includes the right the use and possession of the property for life. Only the fee owner can sell the property or rights therein.
They can only sell their rights to the property. Which only last as long as they live. No one would accept a mortgage on a life estate.
Yes. However, the life tenant must release their life estate if the owner wants to sell the property free and clear of the life estate. If the life tenant does not want to relinquish their right to the property the new owner must take the property subject to the life estate.
An executor cannot sell the life estate. If the sister was given a life estate she has the right to the use and possession of the property for life. The property cannot be sold without her written consent.
A life estate with no powers means that the individual holding the life estate does not have the ability to sell, lease, or mortgage the property. They only have the right to live on the property for the duration of their life, after which ownership typically reverts to another party, such as a remainderman.
You seem to be describing a life estate. The holder of a life estate in real property cannot sell the property because they don't own it. They can transfer their life interest to another person but it would still end upon the death of the original holder. The exception is states that allow "Enhanced Life Estates". Florida is one example. The owner of an enhanced life estate can sell the property.
