I am from Tucson and familiar with the area as I traveled to Sierra Vista, Tombstone, Benson, Bisbee frequently.

People like reviews and what other travelers have to say.

@Chris KennedyI raised the question due to the usage of "adjustable-rate mortgage" (ARM) which is common in the U.S.A. but more frequently referred to as "variable rate" here.  

Yes totally makes sense for that usage. 

I support myself and travel the world by working online (teaching English and social media marketing). 

If there is a title insurer willing to issue owners coverage without exception to claims of unknown heirs or the use of a power of attorney (I highly doubt all your foreign sellers will travel to the US to dump this property), then things should be fine.That, however, does not eliminate the need to deal with FIRPTA.

Note: If you go to the same meeting each month, you can do detail tracking for a month, and can use same detail to estimate expense for rest of the year.( If nothing changed)2) Meals when traveling away from home - 50% is deductible unless the meal is provided to the general public (like Open houses) than it is 100% deductible.3) Expenses for Meeting with investor4) Expenses For Meeting with realtor5)Going to investors meetings.

It starts slowing for months and the early warning sign is increased inventory (non seasonal), then prices travel down over months or years.

Do investors travel to these properties to view them before making an offer, or at some point after an accepted offer (during inspection s)?

Living in the house also allows you to monitor usage and try to keep the costs lower if you need to.
