We bought an apartment building last year, and it was next to a car dealership/auto repair shop which existed many years ago, and there is underground oil tank close to the vicinity of our property.

Charles Village area.

I use Cozy and it can be set up to auto pay by the tenant using the app.

You can find property in Fisk, Charlotte Park, Chestnut Hill, even Hillsboro Village with this type of zoning.

We are also about to test an leak detecting auto-shutoff valve.In a multi-unit building also remove - or place behind locking plates - any hose bibs to avoid tenants washing their vehicles or running sprinklers for their kids.I would be very surprised if you would be permitted to drill a well within the City.  

That may be a little aggressive if you want to buy something turn-key in an A+ area and go on auto-pilot asap.

Good areas are Sherwood Forest, University District, Indian Village, West Village, East Villiage, Woodbridge, Boston Edison, Corktown.

Also charles village is in walking distance.

If Buyer buy, they are covered.Like auto insurance, one at fault will be responsible.

That is with the .25% discount for having auto payments. 100K line.
