i borrowed 50k from my 401k to buy a 68k property.interest rate is 3.25%, paying over 5 yrs, so roughly $900 out of my paycheck goes directly back to them/me. other than losing the purchasing power of that 50k, it's one of the best decision i ever made. 

You have zero power to mediate anything between them.  

I can only speak to my area, but in NJ there would be penalties for cutting the power off.

As I am starting with a clean slate, how would you all attack my situation if you were in my shoes? 

This step ensures that the title work has been done and both the borrower and you have clean title.6) Recording of the deed.If the funds are being loaned for construction, I would lend the money in draws, upon completion of phases.

In my mind, the help from my mom is a powerful asset that we can both use to get our feet wet with real estate. 

Another lawyer ***** that I the displeasure of closing with, she chose a time for closing one day, and when I arrived, she was at lunch, she berated the staff in front of me for stupid stuff, really struggled with the power of attorney we have used for years (made by another local lawyer) and ended up writing her own power of attorney - That she wouldn't even let us keep hold of???

One of my wife's uncles was in charge of one of the properties which is zoned for commercial/residential, it is a 1708 Sqf office space/small warehouse on .36 acre lot.Which with some research it can be split into 2 lots.He let the property go to the dump, needs a new metal roof, and gutted, replace plumbing/bathroom, replace electrical etc...Now my wife’s Aunt is in charge of the estate and she was the one who approached me.She said they will "sell" me the property for $30K (estimates from Real estate agent say property is worth $43-$53K in current condition) Which then I could clean the property up and try to resell with the improvements.Now if I did replace the roof make the inside look nice and clean the overgrown landscaping I was told (real estate agent) it could get about $60K, but there are back taxes and liens on the property as well.Plus closing cost for when I sell it, I have run the numbers and it seems that I would MAYBE make $3000-$9000 conservatively.But I am real concerned over the fact that it is used as an office/commercial, and wouldn't this limit buyers?

From what I have heard and it makes sense if you invest in an area that is being cleaned up people will move there for cheap housing, hipster types will build businesses and it will be good as long as you stay in that area and have some plan for keeping crime out.

If this is a summary probate (PC 13150) there are no interim duties or powers granted the petitioner.
