So convenient for people moving or building/buying something else.  

That is gambling. 

You get to learn a TON about how your business should work, and will avoid losing loads of cash to a management company—they may be convenient but the good ones aren't cheap.Plus, it's not too hard to find good software and tools to help you out with managing, if you want something more solid than an Excel sheet and a contact list.

"Gambling" that the value of the asset will increase also has its risks.

Tough to do part-time as you're having to hustle to find clients and show apartments when it's convenient for tenants. 

No way to make money on that deal if there is no equity and if it is underwater.If you could get it for $0 down with her carrying the mortgage, and it would cash flow well, it would still be a gamble to consider but the risk would still be on her. 

Reward yourself and make a great decision for your future and don’t just get lazy thinking on convenience now when that may have consequences for the future.

Call your tenant, get their availability and then work with your mortgage company for a mutually convenient time. 

If you really want to gamble your risks would be lower at the race track.
