If college students are going to cram 5 full-sized adults in a 3 bedroom/2 bathroom home you'll get a lot of wear and tear, parking is a pain, noise complaints in a family neighborhood, the occasional kegger, etc.

And it's infinitely harder to kick out a tenant for breach of lease agreement - say for excessive noise, or guests that scare your other tenants, etc.  

She actually wanted me to tell another tenant to get rid of their air conditioning unit, because the noise was bothering her.  

They're noise nazis or plants on the balcony nazis or anti-rental nazis.I owned one for about 3 years and made a profit, but couldn't WAIT to get out from under the HOA, and yes, I even got on the board to try and add some experience/sanity to it, but it was a losing, insane battle. 

Initially you'll be grinding for the money unless you have a good friend or relative.

I'm going back out tomorrow to keep fishing for them though i'm grinding to get them both.

-Noise is VERY difficult to evict for.  

I hate the pens that make a noise. 

Oh, that noise you heard? 

They are easy on the property, they will stay for the long term, they are respectful, noise is minimal and they pay on time all the time.
