But I guess I’m assuming a $10k mobile home parked somewhere nice is worth more than one parked somewhere undesirable.

Then they will have to work it out amongst themselves if one person does not want to pay his or her share.Unless your house is in an undesirable area I would probably keep searching for better tenants.

Undesirable neighbor, needs new garage door and front doors already.  

it looks the "deals" are more in undesirable areas. 

Although making money is important, I love the aspect of improving distressed neighborhoods and transforming undesirable properties into something beautiful. 

We based our decisions on which units to remodel and when upon the (un) desirability of the tenants.  4 years later we still have 2 of the original tenants.     

Are those considered highly undesirable by good tenants?

Most are undesirable, some fare, none good in my opinion.Is it possible after reno work to target a better quality tenant demographic or is it in a D grade area.Why is the place paid off, you should be leveraged since this property would likely cash flow with 100% financing.

I hear a lot of talk about how 2% is near unobtainable unless it is a c class or in an undesirable neighborhood..  

Unfortunately it was 45 mins to my property and we decided it was geographically undesirable long term.
