Background for the question: My husband and I live way below our means.

@Maria LunaLink below is to a free excel spreadsheet template.

I am planning the structures to be low-end to mid-end duplexes, triplexes or fourplexes that have a unit size of 900 square feet to 1,000 square.Any input is appreciated.

Also, high property tax in Chicago.The below link gives top 100 markets forecast for 2018, and can't go wrong with top ten.

@Danny MallerNext time, and as you build your empire use the link below to look up any City of Chicago code violations. https://www.cityofchicago.org/city/en/depts/bldgs/...And if you cant remember this link just google "Chicago Building Violations". 

Pricing your unit at or just below market rents will get you your pick of tenants.

If you have any of the below contractors in your network and wouldn't mind providing a referral we would appreicate it greatly!

They send out mailers and pretty much acquire plots for bottom dollar, and go for the quick sale below market value ("land wholesalers").My question: How do I keep myself safe if I were to proceed with this seller financing?

Currently getting $1150 for rent, which is at least $150 below what it should be.
