Though accidents could happen, 99% of the time these issues that most people need to get policies for are due to the lack of common sense or for someone accepting responsibility for their actions. 

Or is it common knowledge?

I've heard from several people who thought they had an owner finance agreement signed at the kitchen table, assumed they were paying down equity only to have the house sold right out from under them.Ben,  How common is this that a seller is willing to give up their deed upfront in exchange for seller financing.  

Heck it’s common practice to make someone aware of an impending obligation.

A missed sewer line can be a 20-30k repair alone, but more commonly you are going to be over budget $500 here, $1,000 there, and when you add it all up, it becomes $20k very quickly.

We could sell that house by itself, but it would be sold under a land in common agreement and an HOA would need to be formed.I also confirmed with the Public Works department that a 2nd driveway can go in, with a septic designer that there's room for second septic tank, and with the public water company that they can tap into the main water line from one of the neighboring roads.I'm sure there are some more details that I would need to iron out that the code officer didn't bring up, but the high level answer I was looking for is that my town does allow selling off a second house under the LD 2003 legislation.

Hi Antonio,The most common way investors scale their portfolios is as follows:1) A cash-out refinance on their current investment properties.

This is clearly a shakedown, and while I'm not a lawyer and wouldn't know what law it violates, it certainly must violate one or more laws to purposefully conceal what the correct address is in an attempt to have the LL violate housing laws, and thus profit from it.I would request a freedom of information act request, and ask for all documents related to the previous 80 cases, as there are bound to be common themes, such as "attorney claiming to have sent a letter", but all 80 landlords mysteriously never got a letter. 

Common meter for water.

Like Michael said, I would use a cleaner once a month to clean or biweekly, restock the common area items (like TP, dish soap, etc), and sign up for routine lawn and snow services.
