Other neighbor offers to build him something with it, and ends up building him this big blanket chest.

We use to rent with naked windows, but grew tired of tenants trying to hang their own blinds or curtains ... or using a blanket and push-pins.  

@William DavisI can't answer your question, nor can anyone else without knowing the process of accomplishing "a way to minimize your tenant's rent without losing money".I like the sound of "making our air cleaner without switching from gas vehicles" but not if the strategy is killing half the population of people who drive gas vehicles.People are "so quick to judge or make fun of the idea when you don't even know what is" because we don't know what it is and making blanket statements/ asking generic questions and saying "I cant say" when people ask what you're talking about - sounds sketchy.

@Gelbu Sherpa, Refi's do not impact tax or gain. 

A Blanket loan may be a good option and you might be able to pull some equity out right away on existing properties.

If you get sued with a "blanket" or "umbrella policy" they can get at ALL of your equity in ALL of your property as well as your personal bank accounts and private vehicles, etc. if the house that gets sued is in a different LLC from the rest, they can only go after what is in the LLC.

Every building is kinda unique and each carrier has their own appetite so it's hard to make a blanket statement. 

I don't play with hard money, blanket, cute, commercial or car loans, so I'm enjoying this time with my family. 

Seems to me that proves the point conclusively (certainly in my case it does), that LLCs amount to little more than a ridiculously expensive false security blanket for wildly overblown risks that can be addressed much more economically and convieniently by other means.Of course if you're seeking affirmation of your choice to utilize something from a class (i.e., many many attorneys) that stands to benefit from it, the answer will always be a fait accompli.

GH is almost entirely blanketed in single family homes.
