Currently there is one oil tank supplying fuel to two oil furnaces and I'm looking to convert it to two separate natural gas furnaces.There are already two separate gas meters running to the property, and each unit has a gas range and a gas water heater, so I believe the lines running to the property could handle two new high efficiency gas furnaces and tankless water heaters.Anyone have a good contractor in the Boston area who you'd recommend to do the work? 

You can take two routes, there are many more but these are the two I considered. 1) buy a rental that cashflows and helps you build up that savings account for another property and make that go faster. 2) What I did, is I bought a property that was under market rent that I knew I was going to live in and house hack.

The building used to guzzle home heating fuel and now it is heated by solar power through high efficiency heat pumps, which also provide efficient cooling for an added bonus.

Your living costs should go down if you are renting out rooms or part of the house giving you the extra money to pay the loans down faster. 

The 130 toll road built about 10 years ago has really helped spur faster development on that side.

If you go that route you may be able to expand a little faster, even if it requires some more cash. 

Helps me get my failures out of the way faster, versus learning new issues in different investment types. 

I would recommend buying a property or two of your own first so you will be able to learn what your doing faster.

Its a very expensive camera when you purchase the separate flash, total was around $1,100 but the picture quality it takes will help you sell homes faster as they will look better.

Shawn Clark, I happen to be of the same mind as you when looking for wholesaling to end buyers- cash offers faster close times & fewer financing issues.
