The list of cities that I’ve come up with so far by my own rookie research is the following, but always open to other suggestions from members that have experience else where. 

For example, population growth in certain neighborhoods and increased investor activity have created opportunities for both long-term rentals and value-add deals.If you’re torn between wholesaling and holding long-term rentals, I’d suggest thinking about your long-term goals.

If you're looking for the all-in-one I'd go with a PM software (others have suggested some) and do what you can with it.Then, as you grow further, look at more sophisticated/expensive options.

Prosper averages a 3-4% default rate (I would suggest 5% to be conservative).I have been investing with Prosper since 2007 and their loans absolutely default.

Honestly if the property taxes are enough to make the rentals a bad deal I’d suggest selling.

Here are a few suggestions on how you can maximize the wealth of information available: Check out the blogs and podcasts, or take advantage of the search feature (magnifying glass).

That would be my suggestion.

I'll definitely check out Set For Life by Scott Trench and The Total Money Makeover by Dave Ramsey for more financial insights.Watching BiggerPockets podcasts and networking with local investors are great suggestions.

If you have lived in it for 2 yrs I would suggest renting it for 2 - 3 years and then selling it to avoid capital gains taxes. 

My suggestions would be in this order:(a) Determine the type of financing you qualify for - this will short cut the process considerably and save time on investment angles and next steps.
