@Aman S. we have these installed in several parks and at our business. 8 months in so far so good. 

Specifically,- Is older basement water tight or needs French drains and sump pump installed?

I haven’t installed any digital locks for the rooms, just the exterior.

Has anyone tried installing wifi locks and security cameras for their long term rental?

I would then buy all those interior design pieces and install.

It's a once in a lifetime installation. ie, by the time a metal roof needs replacing, you won't be on earth to worry about it.

Vinyl plank flooring is affordable, easy to install, and resistant to moisture and wear, making it ideal for high traffic areas like stairs.

Many OOS investors set themselves up for failure because they don't truly take the time to understand:1) The Class of the NEIGHBORHOOD they are buying in - which is relative to the overall area.2) The Class of the PROPERTY they are buying - which is relative to the overall area.3) The Class of the TENANT POOL the Neighborhood & Property will attract - which is relative to the overall area.4) The Class of the CONTRACTORS that will work on their Property, given the Neighborhood location - which is relative to the overall area.5) The Class of the PROPERTY MANAGEMENT COMPANIES (PMC) that will manage their Property, given the Neighborhood location and the Tenants it will attract - which is relative to the overall area.6) That a Class X NEIGHBORHOOD will have mostly Class X PROPERTIES, which will only attract Class X TENANTS, CONTRACTORS AND PMCs and deliver Class X RESULTS.7) That OOS property Class rankings are often different than the Class ranking of the local market they live.8) Class A is relatively easy to manage, can even be DIY remote managed from another state.

I am thinking things such as:-Sewer & water lines to public or the installation of a well / septic system.

I had an emergency water heater issue, here how they treated  me1) They have few plumbing companies they deal with who have horrible reviews and you have to go with them and wait for atleast a week before they can approve you.2) Once their tech diagnoses it,  Now AHS says installation is not covered and they want to order a water heater themselves which would take many days.
