This is similar to how homes get sold for Habitat for Humanity or other programs like that, they record a restriction sometimes with a repayment provision if you were to not abide by their agreed stipulations.

3) Do other investors set up a unique bank account for the income and expenses by property?

While everyone's insurance rate is unique to them, 1500 does sound pretty high.

Everyone has a unique rent amount so in case they do not leave a teller memo I can still tell who paid their rent. 

I have a unique combination of factors that make me able to do a lot of research. 

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).Please keep in mind the multiple loan rules:Under those rules, the sum of the balances of a participant's outstanding 401k loans under a single 401k plan (using the highest outstanding balance of each loan over the last 12 months) can't exceed 50% or $50,000 whichever is less.

If selling the property to a buyer that also plans to live in the property he also offers an MLO service to handle any disclosures or ability to repay test that might apply under the Dodd Frank Act. 

Then immediately get a loan by refinancing the property, repay my parents with whatever I get from the loan plus money from my own pocket to equal up to the amount that they gave me (assuming you can only get 70% of property value). 

I am looking for some feedback regarding an idea that I pitched to our primary appraiser regarding a unique selling proposition for our company.  

Ann Arbor is very unique.
