The biggest reason for this that I've seen is the ability for each owner to separately complete a 1031 exchange following sale. 

You have the ability to do delayed financing in the first 6 months, if you paid cash. 

In lower income areas, the biggest concerns brought up were quality of tenants (how they will treat the property and ability to pay rent on time), and also the limit of potential value.

If the lender has a certain fixed cost for loan processing and underwriting that has to be covered by the loan fees, then the lender may not offer small loans where the maximum allowable fee does not cover the overhead.Qualified mortgages can not have an interest only period, can not have negative amortization, can not have a balloon payment, and the lender has to ensure that the borrower has the ability to repay the loan.  

We all have skills, dreams, goals, and personality types that bring distinct advantages to your ability to be a success.

Both...maybe you have the ability to purchase a simple property near the college and househack with other students.

Now, having said all that, house hacking isn't necessarily easy (if it were, everyone would do it)...it's just easier than the more advanced strategies...House hacking still takes significant due diligence, skill in analyzing the market and the property, time and effort to learn about tenant screening and property management, the ability to anticipate appreciation/depreciation trends, etc., etc., etc....and even with lots of skill and preparation, things will still go wrong (vacancy, plumbing leaks, bad tenants, etc.)

I understand how balances and minimum payments may affect the ability to pay rent but what does providing account numbers do for the landlord? 

It has everything you need from free online videos and educational courses to having the ability to post blogs and connect with other investors, the possibilities are endless! 

If that's so then you may look at your ability to analyze/monitor/manage a property from overseas and decide to hold or sell independent of tax consequences.
