I'm with @Marvin McTaw and personally think his lease option as an exit strategy is an outstanding idea!  

There is metra access to this town and easy access to major highways. 4.

3) Will the death and transfer of ownership trigger any default clauses in any loans that may be outstanding?

Being that you are in South Arlington spend some time driving pockets in zips 76016, 76017 (there are some good duplex pockets right off of highway 287 on the right side before you get to Little Road.

The repayment terms for a 401k participant loan are equal monthly/quarterly payments of principal and interest (typically prime plus 1%) over a 5 year term (longer if used to acquire your principal residence).Please note that if you take a full $50,000 and then pay back the loan, you can't take another $50,000 until 12 months after the first loan was fully paid back.Per the loan offset rules that went into effect with the 2018 Tax and Job Act: if you leave your job and the loan is current at the time you leave your job but then the loan goes into default because you left your job, you will have until your tax return deadline (including any timely filed extension) to make the loan current by depositing the outstanding balance into an IRA (and thereby avoid the taxes and penalties that would otherwise apply).4) The loan must be paid back in equal payments so making pre-payments won't lower the monthly payment but will shorten the term. 

The house has outstanding taxes (the $7K) with a face value of $100.6K.

You only pay interest when you borrow against it and while there is an outstanding balance.I have someone I can recommend, if you want to discuss with a professional.

Generally speaking, stay in areas East of the 75 highway that runs thru the city. 

You do accumulate an outstanding balance which appears on your credit, but not as delinquent. 

Hey Scott,Michael and I are working on rehabbing our 3rd cabin along highway 2 before Stevens Pass.
