All things change with time and circumstance!

There may be other circumstances, but the point is I want it for only a short period of time

Any price I put out the door, would strictly state "for budgetary purpose only" as pricing would change dramatically in some circumstances.

I will search the forum for other similar questions and see which answers best fit our circumstances.  

An LLC buys you nothing from a tax standpoint - it's all about legal protection at that point.Holding rental properties in an S or C Corp is also generally not a great idea unless you meet a very specific set of circumstances.

Although yes it is not simple and like any tax saving strategies you need a prudent accountant and tax adviser, I would never recommend someone try that on their own.In the same breath to contribute to the conversation about mortgage insurance premiums, I leave it to circumstance.

LOL, I realize this is far-fetched . . . but, I'm always on the lookout for potential legal problems, so I want to avoid that possibility no matter how far fetched.I'd considered doing 3 individual leases for the other 3 girls, but that seems riskier to me for obvious reasons as well as just being a big PITA, especially considering that I am sure that some roommates will come and go over the years.So, how DO people set up leases in this circumstance?

@Shannon Phillips ,The rent control exemption for Section 8 applies to the circumstances of the tenant, not permanently to the building or to the individual unit.

What was the biggest unforeseen problem?

While there is never only one answer that is correct for all circumstances, there is a general rule that is almost always the correct choice.
