At various times during the past 25 years he “specialized” in oil and gas drilling, franchise sales, surgical center investments, office centers, start up incubators, vitamins, mobile washing equipment, cemetery syndications, residential mortgage brokerage, commercial mortgage brokerage, insurance as an investment, long term care insurance, and property development in Mexico.  

Tough to spend $50,000 or $500,000 on gas and groceries.   

Lawn, snow, electric, gas, water ???

That's three hours out of that manager's day, plus gas.

You would want to check local zoning to make sure you could build more than one as a lot goes into that beyond just being close to plumbing, electric, and gas.When you mention "a lot goes into that beyond just being close to plumbing, electric, and gas," what are the top things people tend to overlook when preparing to build ADUs?

People think it's inexpensive to install a Washer & Dryer, but getting the gas, electrical, water, and drain/vent there is usually quite expensive.Here in Chicago, we always want to be at the top of the market regardless of the competition, so we almost always install a W/D when we renovate our properties, even in some of the less desirable neighborhoods.

he has also asked for each electrical panel to be labeled and also gas meters to be labeled.

Fortunately I was able to add a 30” model...so I got to spend $400 on a nice whirlpool stainless gas range that looks decent too!
