However, as @Walt Payne said, i'd love to see more historical data on the reliability of their protection since they are a newer structure.

Would greatly appreciate any insight or experiences you have had with data mining and statistics in your ventures.

It does have a lower cost of entry than other forms of REI, but there is an upfront investment to be made, primarily around marketing. 

Some of this data can be found online (if the county offers this service).

Your scenarios should be based on the confidence of your projections (in statistics, it is based on the # of standard deviations from the norm based on the type of distribution for your data).

What are entry level positions like in Real Estate? 

So I use to do A/C work before I went back into the Army...What I would tell you is before you buy your next property, walk outside and check the data plate on the A/C system.

.***   There is are 3 exterior doors, so the units do share 1 entry way that has a inside and exterior light.***   I'm fairly sure I need to install hard wired smokes (building is 100+ yrs old) and since they are shared, i'd have to put these on an owners panel?

In the process of developing my initial REI plan, I've already ruled out the boroughs due to entry level pricing/poor value.

- Are they giving you the adjustment entries at the end of the year?
