From the manufacturer these typically come with the pink insulation and then either a plastic or mesh "underbelly" to keep out rodents and serve as a barrier.In the south we don't like breathing between the underbelly and subfloor due to heat rising and to support ventilation, but in the north they have a mesh to allow for the opposite.  

., one quick thingy: concrete floor sound index should be around 25 by itself.i think residential you have to be around 55-65 as a sum/wholefor your own good (or kids if you have or plan to have little ones) if floor not including heating, use something with thermal isolation properties (cork, other thick-ish substrates).your comfy-cozy feet will thank you in the winter.or just add rugs all around needed areas. just careful with back material (not to scratch wood/laminate from repeated moving actions).oh and calling @Linda Liberatore (does the @ thing works on new BP?).

For $300,000 you will get an old little bungalow that doesn't even have heat.

Jeff at Simply AC and Heating is good. 

Pairing it with a heat tolerant ground cover will also mean no weeding.

He feels its better to have 1 roof, 1 heating system and 1 landscape and a whole bunch of zeros. 

Many of the log cabins come pre-fitted with electric/gas heating and modern fittings to retain heat.The reason I want to invest in log cabins is because they are cheaper than single/multi-family houses, and there are many log cabins situated within 5 Star resorts for as little as £50,000 ($70908.50).I am also a first time investor and it will take a few month before I feel confident enough to invest.Do you think that investing in log cabins would be a bad investment?

And, how is the building heated?

Has that baseboard heating unit been recalled?
