In order to relieve the financial stress on me and my siblings, Real Estate seems like the best faucet to find the passive income my parents will require soonI'm seeking to network with people and learn as much as I possibly can.

She and her 3 siblings evidently have the property tied up in a lawsuit - but the 3 siblings have not made any tax payments.

Thanks for the replies both @Joe Villeneuve and @Steve Vaughan for the last year or so I've been studying real-estate, got my MA state agent license, and was left 100k from a deceased family member.  15k passive income a month is meaningful to me because that is what I feel like I could support my parents, my family, pay for my siblings college tuition amongst then being able to use that time that most people spend working a 9-5 to pursue other hobbies as potential careers, travel, with the ability to be very charitable while not having to stressfully worry about money.

Its possible yes from prior marriage, maybe one spouse co-signed for their sibling to get a FHA loan, but to have two primary residences and the occupancy issue relating from that would be the biggest issue.

For example, homeowner dies and has no spouse or children or living parents, but there are siblings.

Do you advise....Buying a sibling out, peeling wallpaper, painting, changing counter tops and appliances, new carpet, new fixtures?

One is, getting all four siblings in agreement.

Look at siblings that share the same genetics.

One of my goals with investing is to be able to teach my younger siblings & family in Atlanta to do the same. 

But the far greater returns she will likely realize not investing into real estate will replace that cost much quicker than the anticipated returns on a real estate portfolio will replace the fees associated with that asset category, and the utilization of a property management firm to manage the portfolio will come along with an average annual and ongoing cost of 10% per year...every year, where as the taxes are a one time hit.I'm advising you to consider this alternative and to engage the rest of the sibling group in a conversation with your mother as to the overall wishes, desires and individual and collective thoughts on the matter at the same time.
