An example is let's say you get $200/month for cash flow for 3 years so that's $7,200.

For example I know in many “flips” an investor invests 100% of the money and the other party manages/completes the rehab and then each party splits the profit.

And an example might be the difference between painting a wall and "touching up". 

For example there are pockets of Harrisburg where south of one street you have properties going for 180-220k range and north of that street properties are going for 35-55k and they are in rough shape with shootings/drugs nearby. 

Examples can go up or down depending on rehab and buying preferences.

Because that's still their lease and the lease you are taking over, even if they are month-to-month.For example, on a month-to-month tenant, I can serve a 30-Day Notice to change an item(s) on our lease. 

Your situation is a very good example of when NOT to do it yourself.

Owning and operating a property management company is a huge complement to owning a real estate; owning a bookkeeping or CPA company that serves real estate investors; a construction company is another great example of a small business.Again not sure where you're heading with your question, so hard to give a precise advise. 

Let's say, for example, I'm looking at a SFR with a market value of $300,000, but my numbers don't work above $250,000.Now, a $250,000 30 year mortgage at 4% would run a little less than $1,200/month, with total payments of almost $430,000!

For example: Say you, as an individual, can only spend $100/mo on marketing in a given zip code, you might get one lead per month, which leads to one new listing or sale per year (assuming an 8% conversion rate).Now, say you team up with two other people, and start spending $500/mo*, which leads to 8 leads per month.
