I'm a very systems-thinking type person which is why as I'm trying to navigate this investing decision for myself I'm thinking in terms of best practices and abstractions that probably seem odd or out of place to some people. :) 

In my opinion, the most important thing to consider in metal roofing systems is exposed fastener vs. hidden.exposed fastener- Metal is actually screwed down to the roof deck through the face of the metal.

@Tom Campbell I use a system called roi muse, I have put in the offer price financing terms and expenses on based on what seller has told me and other collected data.

I'll definitely work to create a system to do just that.

They're going to spend billions on a rail system that won't help.When the earthquake hit in 2006, people freaked out and bought up all the bottled water and rice just because the airport was closed for a few days.

In the end, there's no use preemptively investing in systems, multiples of tools, employees, workers comp and all the overhead to take your business to people who will low-ball you or haggle or just want a guy who has a license who picked up a day laborer/helper to get it done quickly and satisfactorily.

As far as I know, Propertyware is the only system that allows custom fields.

Sure, some people make a killing off of low-end rentals but it is extremely time intensive and you would need to have your systems/processes firmly in place.

As an example, I am in Charlotte and we use a light rail system.

MA has very tenant friendly laws and people can try to game the system as much a possible, I've heard some horror stories from friends of friends about bad tenants that were able to stay in an apartment for over a year WITHOUT PAYING RENT!
