Some of these properties are unusually shaped, heavily over grown, but not necessarily in horrible locations (on a busy road, in a dangerous neighborhood).

Often they have so much work they drop your home flip and go the next smaller job and then come back.In most cases you are the general contractor coordinate different tasks and heavily involved on a daily basis to see it gets completed. 

As for the question of turn key versus doing it yourself, that will probably be heavily influenced by market. 

If I can buy a heavily discounted SFR and get a great yield then I just want to know what the yield is so I can decide whether to buy it.

@Adam Rothweiler so Real Estate is heavily focused on one of two things, sales or capital.

Due to this though, I believe a lot of fix and flippers who are not as well experienced are not as profitable or may not be profitable because bank owned and lower priced assets are not as heavily discounted 

Oil companies may also have a tie in with the equipment lease.The absolute best situation is to own the real estate, own the operating business, own the equipment, and have no long term contract with any gasoline provider, in a heavily trafficed location with no direct competition, and a high volume dealership.  

@Gary MontgomeryYour first year is going to be the most difficult because you will not have any tax returns as a SE investor, which is heavily weighted for bank underwriting. 

Bad part was that I was heavily involved. 

I think it depends heavily on your seller's situation.Cash offer to a seller not in a hurry with financing contingent offers in play?
