More importantly I looked at how technology could not only improve lifestyle but cashflow:(These are general numbers not associated to a specific product, please price your own product and charge +/- accordingly)30 Unit Apartment$150 deposit per 2 "smart keys" (returned if 2 undamaged keys are returned - kept if not returned)= $4,500 on deposit at capacity$75 replacement - This will bring in a few hundred a year minimum on this property(Make sure your replacement cost to the tenant is more than your key cost for the hassle of reprogramming and to be paid for your time and cashflow, consider it like a contractors markup for services)If I pay $200 a lock I am in for $6,000. however in year 1 I receive $5k+in deposits or replacement fees that could be realized.

The Cook County Human Rights Ordinance: This ordinance prohibits people in Cook County (including employers, landlords, property managers, real estate agents, store and restaurant owners, bankers, lenders and Cook County government officials and employees) from unlawfully discriminating against or harassing other people on the basis of that person's race, color, sex, age, religion, disability, national origin, ancestry, sexual orientation, marital status, parental status, military discharge status, source of income (including use of a housing choice voucher), housing status, or gender identity.

You might lose some money but hopefully it pale's in comparison to what you are able to accomplish.I have seen a few investors come my way who were really- I mean really smart people.
