It is different if you are the owner as you have the risk, maintenance, cap expenses, etc.  

Even if you wanted to save that expense, you should "pay" yourself that amount by allowing for it as part of your expenses.The problem is: a bad Property Manager will cost about the same dollars as a good one - but your expectation of positive investment returns could be reliant on finding/being a "good one"!

Given that the north side is so expensive now.

Hi, I'm a 27 year-old engineer looking to learn about commercial real estate investing in order to acquire properties that will provide a steady source of cash flow that will allow me to continuously add to my potentially higher-return stock positions, as well as cover living expenses. 

One way or another, however, the investors must work to pay down loans, increase rents and decrease expenses wherever possible.

Does "everything" include the estimated expenses on a rental property.

There were some expenses which we could not predict because the former owner had stripped out all the appliances etc.  

There are other bonuses to hiring a spouse for your business such as the ability to open a Medical Expense Reimbursement Plan.

Just make sure your offer contract allows you an inspection period with the option to back out if your inspection comes back with any big ticket expenses that turn it into a bad deal.  

At least just to keep your monthly expenses covered for that property.
