@Paul DentingerRecommend exploring as many sources as possible to get referrals AND cross-reference them to get as much accurate information as possible.Check out NARPM.com, BP’s Property Manager Finder (BiggerPockets: The Real Estate Investing Social Network), etc.Also, encourage you to learn from the mistakes of others - by reading posts here on BiggerPockets about owners not having their expectations met by their current Property Management Company.

I'd just make sure I invest for the right reasons.

I'm sure there's money to be made there in real estate, but it seems to be heavily reliant on one industry (Army) which is a red flag for me when it comes to evaluating markets. 

You can lookup the tax rate on the county assessor website - Make sure you are looking at or calculating the property tax WITHOUT any exemptions (since you’ll not get any as an investor). 

I was looking to see if anyone has some insight on some "must need" content that I make sure to cover as I am creating it.

- @Max Ferguson Definitely eager to start with something relatively simple to get some skin in the game and learn firsthand.

Not sure if it would make sense for you specifically, would need to know a bit more about your situation and everything, some people we help that are looking to consolidate debt consider refinancing to lump all their payments together since a primary residence lending option has lower rates than some of the alternatives. 

I'm learning about this field and I am not sure what sites to trust for gaining information on the estates and who are credible sources.

I have a team of 5 that spend the entire day sourcing deals for my investors.I would say you should connect with a good agent that can show you the ropes and provide you with the right resources to learn the market fast. 

Make sure you have enough room.
