You aren't the insured in this case.Renters insurance does not cover the physical damage of the real property - it covers the tenants personal property and other things. 

Not sure if that is physically or financially feasible to you.

Even new machines can experience issues, and when those issues mean that water is leaking all over your laundromat, you’re going to want to respond to that quickly.It may not be that your laundromat requires that many hours in a week of actual work, but the times your laundromat will demand your attention can often happen unexpectedly.In a typical week, we would work 7-10 hours on our laundromat, either being there physically or working remotely.

Also, note that it is hard to accurately judge an area from afar based on exterior physical characteristics.

Many property managers tend to focus on physical occupancy rates, but what truly matters is the economic occupancy rates—the actual rent collected.

They grow both physically and with inflation.  

It really made me feel better beacause now that I know the site is physically existing! 

Short-term maybe short it, for the reasons you mentioned OP but this investment is a physical long-term one so you analyze it appropriately. 

How is physical occupancy?  

Since you're a citizen but you live and work abroad you'd still qualify mostly for second homes occupancy or investor non owner occupancy (primary is hard to claim if your job requires you to be physically next to the office as an example so an underwriter isnt going to readily believe you unless you can get HR to write you a letter to state you're remotely capable of earning this income/job duties anywhere).Hopefully that helps let me know if you have further questions into mortgage planning.
