Mike, My recommendation would be during due diligence for a potential purchase, ask for past 12 months of all utility bills, property taxes, and any other municipal requirements like rental permits, occupancy inspections etc. 

So utilities, roads, drainage, entries and other infrastructure costs are lower than in a suburban development.

These programs very commonly involve restrictions and conditions on use, refinance, or resale of the property. 

As Sean Wagner mentioned, the city of Chicago has adopted their own regulations on charging what's commonly referred to as a "security deposit" you need to do it another way.

Run an Opco/Propco model.If your business utilizes real estate as part of ongoing operations you can get all the tax benefits of active RE by having the building purchase and hold the RE.3.

The idea is they want to add more long term rentals to the market to help with affordability.The mid-term market is interesting but then you are covering utilities, internet, etc.

My advice is good advice, but it's common that most people new to wholesaling still think they are going to make a mil in a year and only want to hear the good stuff.

Some wholesalers utilize this strategy because the buyer does not see your wholesale fee. 

I feel in real estate if one is truly involved in it these are two of the most important sites utilized.
