I would imagine this will put a major strain on the insurance companies, which they always recover through higher rates.

If you’re investing in Dothan I would look to roll your free and clear home into a loan on a bigger property that could easily rent to the pilots that are constantly rotating through there.

Usually, if you have reason to believe you got a bad appraisal (i.e. got screwed...it's common), you can complain to the lender, and if you have facts backing it up, the lender MAY, throw out that appraisal, and go to the next person on their rotational list and get a new one.Rules say, you or the lender can't talk directly to the appraiser before the appraisal is done.  

If a couple of things break, you have to have an electrician look at something, a plumber look at something, or you have an unexpected repair, or a few months of not having a tenant, you'll be strained financially.

I'm about to move to a dayshift position with a saturday rotation once every two months, about as good a schedule as I will see in the clinical setting with my credentials. 

Be sure to look at items besides radios too - TNCs (radio modems), power supplies, antennas, rotators, towers, boxes of tubes - especially those the size of a tennis ball or larger - those can be expensive high-power tubes, which we still use in linear (power) amplifiers. 

I looked at lots of options before deciding that flipping was what really excites me, despite the strains it can put on my schedule.

Once you have enough properties you can just start rotating deadbolts between houses so you dont need to always buy new ones.

If I have time, I rotate the first 6 photos as well.

I will add that @Shane Lafleur has a monthly meet-up at the end of the month at rotating locations.
