I am very interested in real estate investing and flipping (I have a decent amount of construction experience) I was wondering what some good resources are to look at when evaluating a property, especially in the Dayton / Cincinnati area.  

These folks do not need to be licensed but there are limits on what they can and can't do, and they have to be salaried employees of the owner or report to a licensed property manager.

If you ask around, you likely know someone in CA investing out of state.If you evaluate a long term rental property from a micro view of let's say the Year 1 return, with interest rates where they are, and using conservative estimates for rent, you'll be hard pressed to find compelling cashflow without going into C or D class areas nationwide. 

You need someone to sit down and evaluate the entity from that standpoint, not just as it relates to income from the property after you got married (and Congrats on the recent wedding!)

Before purchasing a rental property carefully evaluate the appreciation potential.

However, evaluating your sentiment (and your wife's) on that will be important. 

I try to evaluate a unique property 2-3 different ways, then make a highly educated guess based on my knowledge of the market.

Regarding solo 401k, maybe this is slightly off topic, I use equity trust and they say you cannot have any employees other than a spouse.

I heard the servicing company laid off most employees and transferred the loans to another servicer (in some sort of agreement).
