Now , plowing isnt expensive in Md , its just cheap in Maine .  

Make sure you focus on brand quality and sustainability over how cheap it is.For example 2 different brands dent and ding and one is 70 bucks cheaper initially but is very inefficient and breaks down quickly and is a no name brand.

In the big scheme of things in Massachusetts you're getting off cheap.  

Don't be cheap.

Show me a cheap market with "good" price to rent ratios and mostly renters, and I will show you a neighborhood that is going nowhere fast appreciation wise (or backwards after inflation), where CapEx and inflation will erode away your profits over time, turn overs will be more frequent and more difficult to fill, and the class of tenant will be more management intensive, and if that market is out of state you will be 100% reliant on others to acquire and manage it all for you without ripping you off.

A trailer might be selling for dirt cheap but first check if there is any back lot rent owed.

Sediment can be flushed out.For stuff like this I keep cheap spares on hand - it's oh so easy to find a ~1 year old water heater on craigslist for 50 bucks.

It is free to the landlord and cheap for the tenant.  

@Dennis Cuocci  very true... there is cheap money but not the combination of limited experience and capital and poor credit.. those 3 simply do not go together..

Installing a 80% furnace, natural gas is not doing your tenant an injustice as cheap as natural gas is, especially the smaller the house is.
