Another draw back is short term your expenses will be higher because you are paying the mortgage plus paying back the loan but that is a short term draw back until the loan is paid back.How it works: I have experience with my wife's company and mine, each is a little different. 

I operate out in Southern California.

In 2008 a friend of mine spend $300,000 to buy 100 houses in Detroit.  

Mine does not.

Those are not the most important parts of the operating agreement.

In some states, such as mine, you can do one assignment per year without a real estate license otherwise, you will be fined $25K per transaction. 2.

But my question is that if we consider other operating costs like maintenance, capital expenditure, vacancy, etc then this property won't cash flow, so is this a good deal?

Section 8 can be very profitable if done the right way, at scale, by an experienced operator, but I think it's one of the hardest strategies to start doing because of tenancies and government involvement.Most new people just think it's an easy government check and there is nothing that could be further from the truth.

If your leasing application process is thorough and well thought out, and if your lease agreement has been well drafted by your local attorney and if it includes clauses that permit you/your property manager enough latitude to maneuver and anticipate undesirable tenant behaviors, both actions and inactions, and you have operational processes which align with enforcement of your lease, then you've done all you can do to reduce this inherent risk of an undesirable tenant.
