I have a full-time job, so I'd prefer income-producing property rather than flipping, which would be a full-time job in itself.

@Joel Owens can confirm this as he does this regularly.

He has well over 100 of these units producing $500-$600/mo in income so purchasing another is never a problem.I'd say you either need to be able to buy with cash (or private financing) or utilize commercial loans.

Fivverr.com is one I use regularly. 

Since then I've worked to put my marketing company on auto pilot as much as possible so I can focus the majority of my time on note investing.We are working on a seller financing model with several top producing REO brokers and agents that I'm very excited about.I have a 15 year old son as well.

A fourth thing is the taxes on flipping and how much money you lose with profits versus regular investing.Many other risks but you might want to wholesale this as mentioned.

It all adds up...which might be ok for million/multi-million builds - but for the regular spec or flip, it can be costly percentage-wise. 

The best way to do this is to interact regularly in the forums!

The cash flow is great but we will soon be out of mortgages and left with cash purchases or private lending, which do not appear to produce the same cash on cash.I've looked for larger units: triplexes,fourplexes and at some smaller complexes but I can never seem to find any that provide the same return without being in some tough neighborhoods.

Depending on your credit and if you have a regular job you can look at personal loans.
