Though, it is always better to be "safe than sorry".

Quote from @An Lan: I am not a professional real estate investor, I just invest in houses as a safe asset and do not choose to rent them out.

It is a tool, has it's place for sure, but a far cry from universal solution. 

HI, Is opening a LOC on my primary a good option to fund flips or is there a better solution to get the funding?

Prioritize tackling critical issues and beefing up security to keep your property safe and sound.

There are also a lot of foreign investors looking to park cash since US real estate is considered very safe on a global scale.

So while it's not as ideal as a multifamily property, it does present a solution for those that are in the personal situation where they can. 

To protect our rights, we would definitely deliver a formal 5 day notice (Wisconsin Legal Blank), but at the same time indicate that we are looking to collaborate to find a solution.

Personally, if your market tends toward the former condition (better/normal appreciation) I think it's a fairly safe deal looking at the long term, assuming infrastructure around you continues to support the idea of renting it.

It's not about being nit-picky—it’s about ensuring the property is safe for residents.
