is an issue is when it's a business that requires your physical presence. 

I dont use a physical map but it can be very good in learning the area, do look ups of each of  your zips, and sections and record the median sale values so you have the ranges quickly available.

You don't have to physically make a trip down there.

You buy it right, the rest will follow.Trusted local support is KEY: we never even physically saw the property over the entire investment period.  

Always budget time to physically inspect the property.

A 70% physical occupancy is quite a concern and it's safe to say the economic occupancy could be much lower.

There are also services that do some of the non physical aspects (Guesty handles customer service and cleaner scheduling for 3%).

I just want to make sure you're not physically putting any money into it.

Court clerks are paid to archive public records, not provide lists to would-be marketers.If you wish to create your own list, your objective is to build a list of 20-200 by going to the courthouse and physically pulling files to build.

Physically see it, drive it, be there for inspections, etc.
