It will depend on the state but typically in order for a lien to be valid they will need to show a contract with the owner as well as properly name the owner in the suit.

In my area a typical transfer to a new buyer would use a Special Warranty Deed where the seller guarantees the title for issues that happened during the seller's ownership of the property.

that's valid, but that's also the point of a house hack. 

It is likely outside the warranty period, but worth a call to the company. 

Airbnb & VRBO require a valid Boston registration number in order to list your Boston property on either of their platforms.Airbnb has a pretty easy to read help page for Boston hosts.

You can check the documentation, permit info, warranty etc. or often there is an owner’s manual inside the home and also a plaque on or near the inverter or one of the switch boxes with the company name and contact info.

I want to get opinions from seasoned RE investors about home warranties.

I'm talking modest cashflow and wealth-building over time, and my strategy is valid for that.

Save and wait unless you can find a killer seller financed deal.And by relative willing to lend  you $2000 - you will want to ensure it is a gift (a true one).There is a difference between lend and gift and it can have a meaningful impact on if those funds are valid for financing sake.
