It may sound nice to pay a 5% management fee but the extra fees can add up to be more than the other company that charges 10% with no add-on fees.

If you haven't already, speak to the local planning and building department to find out what you can build on the land, what the process is for permits, and what is needed from you to submit for permits. 

If you can find someone like that, it is worth paying a bit extra for their expertise.

Make sure it’s enough profits to make it worth the extra costs/hassles. 

And I can charge them an extra $50 for the electric and water usage?

My prior experience in real estate investment is that I bought and sold a home, and while living there I rented out the extra rooms.

Third , you should go to the city and see what permits are needed , and if you can ,YOU get them

They will call you, harass you because...well... without a permit, they are illegal.

There are only so many buyers, and crossing state lines to sell carries extra risk.

Then when you move to MA you can purchase your primary residence with the VA loan (ideally a multifamily property) and your extra cash you can use to invest.Best of luck my man and let me know if you have any questions about you VA loan benefits.
