I found out job shadowing, interviewing others, and conducting market surveys in person were far more valuable tools than any of my beloved books (except maybe for the rent roll book).

Apart from falling under one of the very specific exceptions (e.g., relocating for a job, your family grew too large and your current property cannot accommodate it, etc.), I'm not aware of any "exit strategy" that would allow you to obtain an additional FHA loan apart from selling the property or refinancing into a conventional mortgage.

Pretty much everything looks good except property taxes.  

There are certainly exceptions, and those individuals are worth their weight in gold.  

If the credit scores are the problem give exceptions and look at the report not just the score.  

I have almost all the books there - with the exception of the book on flipping houses - love their content!  

It went well, except for the fact that I was not getting enough rent to cover the mortgages!

Not so much.... unless you're exceptionally good at multi-tasking and can negotiate with buyers / sellers / investors, etc. while doing demo, framing out walls, putting up drywall, painting, etc.You should also consider your own skills, licensure, etc. versus professionals in the skilled trades and other occupations (attorneys, accountants, property managers, etc.).My $0.02...

They don't seem to want to move and are not much of a pain with the exception of a more than frequently common septic flush (I do this about  every 6 months and I read it should be once a year). 

We have had good and bad posted here about the DF Act and SAFE Act, I did listen to any attorney seminar (D-F expert, but not really) that broke it down quite well for investors, except that he went on to employ trusts, business entities, family members and other types of convoluted exchanges to justify staying within the exemptions.
