If you're unwilling or unable to go in person, don't buy far away. 

The challenge there is that accumulating enough properties to generate cash flow on par with a solid middle-class income (especially in a metropolitan area) requires deploying a substantial amount of capital to acquire the properties, and achieving attractive returns requires careful selection of the properties (to buy below market value), attractive financing, and likely some amount of rehab work along the way -- all of which require a degree of expertise to do successfully, as evidenced by BP itself.If someone is unwilling or uninterested in really digging in to understand REI, they could of course still own rental properties through a turnkey provider or a REIT, but in both cases are giving up some of the upside potential that rewards the patient and diligent.To be clear, I think REI is a great choice for building wealth and Real Estate in some form should absolutely be part of almost everyone's portfolio.

Our strategy is to get as many re-performing as possible (thus receiving cash flow without the tenant headaches), and for those unwilling or unable to pay we offer them cash for keys or foreclose to get the property back.

I think that buying out of sate is a completely viable way to invest in real estate especially if you are unable to unwilling to work with CA numbers.  

Me thinks it's because he read this somewhere and he thinks it makes him sound intelligent but he is unwilling or unable to defend it.  

If the neighbor is unwilling to call the police, its most likely because he/she knows he is in the wrong...or they don't want the police paying attention to them.

@Mae T. if the seller is unwilling to negotiate, move on.
