I am a very active realtor in both the Kansas and Missouri side of the CASEY metro, and I frequently work with local and out-of-state investors, helping folks find small multi as well as STR compatible homes.

Then you have Huntington Beach State Park, as well as Brookgreen Gardens. 

Quote from @Adam York: Contact your insurance provider and let them know you intend to rent out the home.

Providing a starter supply of items like laundry detergent, dryer sheets, and toiletries is common practice and works well for short stays.

I have 1 partner who provides up to 75% of the down payment, however, my goal has always been to live below my means, save money, and invest the saved money as a downpayment. 

Of course the high crime statistics cannot be ignored in these cites, however I'm planning to buy only in the nicer/low crime neighborhoods which hopefully eliminates most of the crime risk.I was wondering if any of you could provide feedback on comparing these 3 cities.

It looks like you are doing an affordable build based on the cost but hard to say since you didnt provide info on the build itself such as square footage and finishes.

Do you know the markets you threw out really well? 

It can be spouse friendly as well.😉.  

The home is in our partnership LLC name as well.
