So, go to this link and scroll all the way to the bottom where you see "LawLine":http://www.nhpublaw.org/nh.law.about/law/24 wow,  you are like a blood hound when it comes to finding information online!  

Unfortunately you cant get blood from a stone.

Their main exports Iron, Petroleum, Sugar cane, and soybeans. 

As Baron Rothschild says "when there's blood in the streets, buy!" 

Just an old RE investor and entrepreneur that can smell blood in the water, just like you.

Like they say when there is blood in the streets.  

Just my two cents, I want to buy when their is “blood in the streets.”

The lease may also include charges for non-emergency issues (changing a light bulb for example).The risk of this is that tenants may not report repair issues they have caused until there is greater damage to your property.Some landlords require that all repair issues that don't involve fire, floor or blood MUST be provided in writing (NOT phone calls, NOT texts) and will be handled in the order they are received.    

It took two years to become cash flow positive on that property, and there was ample blood, plenty of sweat, and no shortage of tears.

See if you can identify the species and read up on the best methods for tackling the issue (see link below).In the meantime (before move in), I would get the over counter traps (little black ones) designed for roaches and put them under cabinets, appliances, etc (blue tape can hide them on the near walls of cabinets or back side of appliances).Then I would get the peanut butter type product designed for roaches that is in a syringe and inject a small dab into nooks, crannies, even inconspicuous places (like inside wall plates).Sprinkle some boric acid based powder (often with a sugar/flour or pheremones) under appliances, behind them, around the hot water heater, etc.
