I'm sure fire code dictates that there needs to be at least two entrances/exits, and one of their exits would be into the back yard. 

I've searched a bit and have not come across a post that quite fits an investment opportunity I have been looking into.At the bottom I put a cliffs notes version of the building/surrounding area (probably could have shortened it up, and maybe I'm looking at too many external factors - however let me know)My thoughts - building would be good structurally/mechanically - located in the downtown core - building is already built out into 4 offices and reception area main floor with a kitchenette/half bath2nd floor has 7 offices, 2 baths, 2 storage rooms2 entrances into the building, street parking on 2 sides, building is located across from the local courthouse(Could potentially turn the upper floor into a couple of apartments or one large apartment - rent for 800-1k a mo for one large apt, however rehab $$ would climb - city would be more than willing to change zoning for this and encourages this type of arrangement in the historic buildings - ie office bottom floor, apt top floor)$60k Purchase Price$20k Rehab budgetPotential gross income $2800 per mo (7 offices $400 ea)Guesstimated Pro Forma--  $33600        Gross Income - 7 offices $400 ea       (5040)        15% Vacancy       (2400)        Property Tax       (2500)        Insurance       (6000)        Utilities - figured $500 per mo/gas/elec/water- think this is high though       (1680)        Cap Ex       (4980)        P&I Pmts $60k loan 5.5% interest - 20 year amortization       (4800)        Janitorial - $400/mo - this would probably be lower----------------------------------------------------------------------------------$      6200        Cash FlowI think I could improve on the above cash flow, not sure the Insurance is 100% accurate, could possibly increase gross income if I have more than 7 offices etc.  

She DEMANDS we come out and put poison in the entrances, and fill the hole back in...

I live in Milwaukee and there are a lot of "Polish Flats" where the older homes were raised to allow for egress and entrance into a lower level unit to accommodate a larger family size (inter generational living).  

Can you install a kitchen and bathroom in the renters' part of the house, and even have a separate locked entrance to their area, perhaps just the whole upstairs for example?

From my research so far Canary looks promising:https://canary.is/ Does anyone have experience with this cameras or other suggestions for outdoor monitoring of a front and back entrance and parking lot?

What I mean is, considerations like parking, separate and isolated patio areas, daylight basements, separate entrances, larger lots so your next door neighbor isn't right on top of you watching every move you make.

James,It looks as though all of the information is all about entrance to the deal.

The complex is an old school board building that has been turned into a 6 plex, all with there own entrance and parking.  

I find it difficult to believe a purpose-built 11-unit building - or even a converted warehouse - would not have separate entrances for each unit.
