Personally, I spent a fair amount of time in college and though I still do occasional work in the profession I trained for that does not constitute a large part of my income.

So just let them know anyone who is going to be around that frequently needs to screened, and listed as an additional or even "occasional" tenant.

There occasional time where issues pop up but they'll be handled and you be assured a clear and marketable title.

@Sarah Kartsher If you keep a close eye on the MLS they pop up occasionally.

Occasionally occupied HUD homes are sold within a year if circumstances change such as a job location change or even a lost job.  

If it is in a park, there is no land value.Park rents are pretty high and I occasionally see or talk to people who are trying to give old mobile homes away and not finding any takers.The cheapest new double wide I've ever seen was $38,000, and it was double wide, but short, so not much square footage.Set up costs can be as much as $30,000 if you have to bring in utilities and install a septic.

As a new investor who is corrently renting an apartment in an apartment complex, I can see the occasionally need for a month to month lease with tenants that are disruptive and a nusense to other tenants.  

I am talking about constant late fees, the occasional is not a problem.

This isn't like a flip where you have a scope of work defined well in advance and have the opportunity to line up people to do the work well in advance especially for most landlords who only do a very occasional turnover. 

House-hacks and STR's are more unique than the occasional LTR counterpart.Furthermore, you live in Philadelphia.
