i will preface by comment by saying it is based more on my legal experience, than as a realtor or investor.
At the time of mom's death, she owned real property and the deed is titled in her name; however, a deceased person cannot own real estate, so by operation of law, equitable title, not legal title, passed to her heirs. Heirs that have yet to be determined by a court of law.
Assuming, her six children are her only legal heirs, each owns a undivided 1/6 interest. For legal title to pass from mom to her 6 children, even if a will exist, the estate must be administered in probate court, where the court will issue a deed transferring mom's legal interest to her heirs.
The court will value the property, which can be a low appraisal or the tax assessment value. Heirs can agree to sell their interests. The incapacitated heir will be appointed a guardian ad litem to protect his 1/6th interest in his property rights.
At this point, the siblings do not legally own the real estate, therefore, transfer via quick claim deed, or otherwise, is a gamble. What if other heirs appear after you have dealt with the 5 who agree?
Maybe I am overly cautious. I am absolutely new to taking risks for investments.
BTW, this is my first post reply on BP.
