I will send you a PM once my wife and her siblings gather some more information.

My mother and siblings live in the area as well as my grandmother, her husband, and my uncle.

My question for maximizing a for two siblings is, can the SFR be 1031-exchanged for an income property (2-unit) without qualms about not exactly being like-for-like properties such as SFR-for-SFR as opposed to SFR-for-Duplex?  

Im born and raised here in Tulsa, live in Broken Arrow and have siblings who live in Bixby and Owasso!

Unless sibling or some family structure of some sort lived in the house then am down only then could the converted building be rented as well and not be frowned upon for its occupancy.

My grandmother passed away in 2012 leaving her house to my mother and her siblings.

Sometimes you even have to let people go (not saying you should dump your parents and run) but if it is people that are keeping you from achieving your dreams (and keeping you crisis mode) you have to consider letting them carry their own burden of making it on their own (that includes parents, siblings, wives, husbands, and kids, etc.).As others have suggested, a job with higher paying wages is the only real solution unless you are going to got he illegal route (it sounds like you and the other working member of the house need at least two jobs).

Also you should get a contract before the following:1) A wedding gift: They are required to send a thank you note and a Christmas card2) Nephews Birthday present: Should be required to call with a "thank you"and dog sit on a future weekend3) Mother asking you to come over for Dinner: She shall be required to sign a contract that she will be making the "Coconut Pineapple upside down cake"4) Elderly neighbor shoveling snow and you help: Should be required to sign a contract that they will wave every time you pass and inform everyone walking a dog that you are a "standup guy"5) Wife makes dinner: Should have you sign a contract that you will be doing dishes every time she cooks.6) A contract should be written stating who is tracking and paying mileage out of their paycheck for doctor visits as well as if she needs to help your parents, siblings, childhood friend and expected compensation.

He wasn't allowed to go to high school, even though he wanted to and his four older siblings were allowed.
