However with that said, can you take square footage from somewhere else to create a hallway or create another entrance into the bedroom? 

nor is pesky repairs that don't show up until a few months or years of a tenant living in a property.i say all this not to discourage you but to arm you with facts. i don't want you to be surprised like so many others are.and: partnering, tapping into equity, anything else 'creative' just means expensive. 

You have to have some skin in the game or else why would anyone risk their money on you?

Yes, this is as niche as it gets, so odds are slim, but I'm curious to hear if anyone else lives on some acreage while boarding other horses on your property?

If it’s not, someone else will outbid you.  

The real estate agent I was assigned passed me off to someone else without explanation, and the general contractor stopped communicating with me once I had my first deal under contract.

Will you be stationed at NAS Pensacola the entire time or also somewhere else like Whiting Field for some of your time here?

It's only 3.5% down + closing costs and reserves.Work your day job, mow lawns, leaf cleanup, shovel snow, flip furniture, pick up night shifts waiting tables/bartending, stock shelves at home depot overnight if you hate talking to people or anything else.

Also, is there some prevision I can put in the lease to prevent the tenant from blocking the drive access to the ADU/Boat and from physically messing with my stuff, such as a fee.

But given that they are so much better at real estate accounting than anyone else, I think it's OK.
