@Brandon P.I use a mix of things and still struggling to find the best solution.All the solution requires to have a mechanical lockbox with backup key at location for lockout or contractor.

Confirm that the provider has experience with the particular investments in which you intend to invest your retirement funds as you very likely will have questions in terms of the mechanics (e.g. how do you invest in real estate, etc.).4.

Zoning, buildouts, service contracts, advanced mechanical systems etc. none of which are encountered in residential.

Call the mechanic or gas station up the street and ask the owners if they know someone.

Not only low-flow, the flushing mechanism reduces the likelihood of clogs.  

As for the first, yes we'd be able to do that (for example, replacing a water heater which is the mechanical that's closest to the end of its useful life).

If companies require you in office, and the companies are based in cities where housing is becoming unaffordable then inherently from a supply-demand mechanism-- there's a short. 

Pre '2010', maybe just maybe it will lean heavier on the fundamental mechanics than specific processes. 

That would be various liens, easement, water lien, demolition lien, mechanics lien, tax lien, water/sewer lien - something that title companies look for, when they do a title search. 

There are never full photos of the mechanicals and basement and roof line so you will never have even a bare inkling of what the potential repairs will be.
