I want to create a GMB profile for a market I invest in, but I don’t have a physical office address in that state.I’ve been looking into virtual address services like iPostal1, but I’m concerned it won’t be approved by Google since they seem to have strict rules about virtual or P.O. box-style addresses.

Your nightly rate will be influenced by proximity to the beach, interior design and amenities (ex game options, fire pit, pool, etc).

Make sure your listing highlights proximity to the base, schools, and other conveniences.Lastly, a personal tip: When renting near a military base, be prepared for quick turnarounds.

Rather then focusing on a market because it is closer in proximity to you. 

They aren't looking for 10% returns and they probably love the idea of getting some cash legally out of Canada.I got into Costa Rica because of the country (it's awesome), what's happening to real estate prices there and in the US (they are nuts here) and the amount of development that's happening around Potrero, the technology advancements in the STR industry, proximity to the beach etc.

I actually have a fee in my lease if a tenant wants me to physically pick up a payment.

In my opinion (I'm definitely bias now, but invested here long before becoming an agent) people are still sleeping on the area with the proximity to Northern CA. 

However, a larger home may consider another can or two in certain locations based on proximity to the kitchen or bathroom.

How is physical occupancy?  

It was vital that the house be in close proximity to the one who knew how to do the repairs, because of the technology of our current time theoretically Id be able to monitor and track progress with a trust worthy foreman whos on the job, performing repairs, managing subs, and moving the needle.
