This incident triggered every trouble I'm experiencing now. 1) The officer from LAHD is after me saying that I need to register the property as a rental property and evict her with relocation assistance, which cost about $9000. 2) The Building department is after me with the order to comply: which I believe it might be better of demolishing the house and rebuild it. 

It will likely cost you to get out of it.

I am just a person on an internet message board, but have known enough attorneys and seen second and third hand enough lawsuits to know you are getting dragged in no matter what.Just a few things to think about before you start spending money to transfer, just to learn that it will cost you a lot more to have things like commercial insurance, commercial mortgage, business utility account (not more expensive, but typically require a large deposit to remain on account), etc.

Scott’s “book on estimating rehab costs” and am having a hard time finding the bonus content.

While completely renovating an MH is cheaper than a SF, it can still be quite costly.

And don't get me started on grocery stores – building one in Worcester instead of Shrewsbury would cost the property owner an extra $220k annually.City councilors, can we please get some action here?

Land costs make it very inefficient to build 1-4 at a time.

After taxes and selling costs we should net roughly $700-850k depending on final sale amount. 

The neighbor's insurance will cover the cost to fix the damage.

And we can nitpick 1%, 2%, & 3% based on our own methods of calculation and what we are individually seeing.
