We have moved to 10 year battery models, so tenants can't forget to change the batteries.

That's pure motivation, thank you.

A building with a couple of apartments and a nice commercial storefront is often a bit cheaper since the pure residential and pure commercial guys are both not going to touch it and it's too small for the institutional investors to pursue it. 

@Arnel BuenoSo this is purely an investment.

Illinois an Chicago aren't worth it in general, and are pure hell for out-of-state investors.

I also included a management fee even if you are going to manage it yourself so I could look at it as a pure investment.

But if you are looking to have this as a pure investment property then you will have to get an investment property loan. 

I would suggest removing all four, and temporarily replace with basic, inexpensive, battery operated units.

Hey Jay,When looking at historic data I do take it into consideration but I personally like to add that information after all of the current data has been looked at and the deal works because even though past info can be an indicator I like to look at what caused it instead of the pure information itself so that I know if it will really continue (if that makes sense).Hope this helps,Romney

It is a special skill set, and probably patience, to work with investors rather than working purely residential deals.
