@Richard J Reid thanks for that ☝ Could you estimate how much, percentage-wise, having this configuration adds to your expenses?

Not including roof, HVAC, windows, replacing plumbing, new panel/rewiring, landscaping, major cleanout or any major configuration changesAlso it's going to vary depending on if you are paying a GC to run the job or subbing everything out yourselfAgain, just a rough rule of thumb for your standard, 400-450k ARV or so cosmetic rehab

What is the configuration of the duplex?

Also a 3/2 configuration is usually having more bids than 2/1. 

I've tried "configuring" the deals in a variety of ways, 40% down, less interest, significantly lower listing price, but a lot of the numbers just don't align for it to be cash flow positive.I'm going to keep looking, but wanted to make sure there wasn't something I was overlooking or glaring.

Combining lines can be a savings as long as you configure the dial-out for monitoring/reporting to be sometime like 5am when no one in the office would likely be using the phone.Cellular and radio-repeater service is allowed for fire monitoring now in our municipality and since we've enabled it so far so good. 

@Jon Holdman The city is well aware of the configuration as detailed plans were submitted to the city before recordation.

Online review “Prolog is relatively easy to deploy, and the cost for a small company to implement the system would be in the range of $10,000 for three concurrent licenses and another $10,000-15,000 for implementation and basic configuration”Landlord Maxx - Aaron Saarela said, “We just started Landlord Maxx which was 199.00 one time fee.

From my practice I can make the advise to use the 1C:Enterprice software: http://risebiz.co.za/1c-enterprise/ This software is very popular between accountants in Russian and Ukraine because it is very easy in use because you can use the already adjusted configurations as for selling or for stocks it is the complete solution for automatization of accounting and tax accounting in organizations engaged in any commercial activity.

IMO, need to segregate LOW-END from the configuration (DUPLEXs).
