Did add extra insulation in between walls for better sound barrier. 

Out of the industry for 3 years, have been doing sales for an insulation company now starting my own edible landscaping and construction business! 

They insulated the outside walls with plywood (so the outside door is now covered), put down a ratty carpet, and have an electric space heater in there with their bedroom furniture.

Not saying don't, but if you are repairing damage and want to permit after the fact you better be sure you don't have to remove stuff, like drywall to show the correct r value insulation was installed, they want r15 in walls here.

An LLC is very cheap insurance and insulates your asset(s).

The window, which was a non-insulated utility window was removed and the sheathing and siding replaced.The house also had a sketchy overhead electric service.

The demand to live here, coupled with the lack of supply will govern housing prices for the next decade, and insulate the region from a larger drop, even if other parts of the country drop (which I don't believe will happen, at least not like 2008)An investment property should be looked at as a long-term investment, one that lasts through many economic cycles.

Insulation.8.

My flip was taken down to the studs and then re-built with insulation, new electric, plumbing, drywall etc.

Typically the investor should be insulated by not only the preferred position but the buffer of income above this preferred position which belongs to the general partner.
