I feel like sometimes you can get a house with a neglected pool for cheaper than one without a pool.  

That said, we have also had tenants whose circumstances changed and couldn't make rent; they then had to move.

You essentially need to be analyzing the up front cost to acquire and renovate to be make-ready and divide by the projected cashflow to see your cash on cash return, hopefully beforehand to see if the needed renovations are worth the cash flow and how long it will take for you to break even, percent of return on your cash investment, etc. to see if its worth your time.Its a long winded way of saying, it depends on how neglected the unit has been beforehand and how well you estimated your maintenance costs.

Under no circumstances may investors use the exceptions described above to circumvent FHA's ban on loans to private investors and acquire rental properties through purportedly purchasing "principal residences". 

Tenant neglect?

They chose different personalities for each caller, they choose the motivation and circumstances, you can set the rest, property info for them.

Now with our new circumstances we figured it was time to look, plus with her not having any income and having animals, renting was no longer a viable financial option.So here we are today, looking at Single Family properties. 

They tend to not appreciate as consistently and as high as SFH in most circumstances, IMHO.

Based off the details below, what are my options and where should I go to start getting adequate information to take full advantage of my current home situation, considering the circumstances at hand?

Even neglecting the $15K second this is not a deal for a fix and flip.
