As part of the application process, do I need to prove to the lender that based on typical rents for similar properties in that geographic area, I would be getting such and such amount of income from tenants?

@Jingru SuiThat does seem high although it might be geographical differences in price.

So there's some factor you're leaving out in your description. 

If the description doesn't say it is included, why expect it and be mad that it is not there?

Are you buying most within a small geographical radius. 

Pick a geographic area to do it by.

Bro that is in no way the proper description of what a turnkey seller should be doing.

The closer geographically the better.People always say that appraisals are "half art, half science". 

Ask the locals their favorite geographic locations to invest, who the players in the area are, recommendations for PM's/Contractors/Realtors/Lenders/etcWhat is drawing you to these markets?

As @Brie Schmidt mentioned, Chicago is a huge market so figure out where your daughter needs to be geographically close to and I am sure there are some neighborhoods around there too.Happy to connect to talk Chicago real estate and help you all anyway I can.
