I recommend you start by finding out what contingencies you removed.  

I would appreciate any help with getting started!

If the numbers makes sense, and you have (or can get) downpayment - the bigger you start the better (and easier). 

That was helpful in decision making and saved time. 

I’m sure there are more, but that’s a start.

As I transition to the civilian life I would like to utilize my VA home loan to start my real estate journey.

We have had really good months starting in June.

Save yourself some interest and time. 

Group insurance: Look for insurers offering discounts for insuring multiple rental properties or join a local landlord association to explore group insurance options.The key is to strike a balance between cost savings and maintaining adequate coverage to protect your quadplex investment.

Otherwise, I would start off from the goal - since you're looking to BRRRR down the line, what is an area you'd like to hold the most in the long run?
