Age is not a barrier in this game. 

It seems that Brandon Turner mentioned in his YouTube video  Enid being the best cash flow city in the state of Oklahoma.

You should meet as many players in the game as possible.

I haven't done a deal yet but have began doing some marketing and have a game plan for when I arrive at my new destination. 

It's hit or miss, it really is a numbers game, you have to commit to doing it regularly for a long period of time, and not get discouraged when it seems that the only responses you're getting aren't really deals.But it can definitely pay off if you're willing to commit to that.

We had a super detailed letter from the dad-in-law on how the husband made a massive game changing contribution to the business, whole 9 yards, didn't cut it.We don't have all the details of your scenario, but when you mention dad as both employer AND cosigner, it starts to share elements -- "the dad obviously really wants you to get the loan or he wouldn't be co-signing, can we really trust those paystubs from said dad?" 

But there is a lot to consider of course, Brandon Turner sums it up very well in this video: https://youtu.be/9Ol2W8SE8b8This is a bit high level, but hope it gives you at least a starting point.

How would go about developing a game plan with them?

Again it only makes sense to invest out of state if you can scale to five properties in a couple of years since vacancies And maintenance repairs are part of the Game.

Now my husband is retired from Blizzard Entertainment Irvine CA after working in gaming for the past 25 years and I run and grow our property portfolio.
