Especially if there are stated reporting requirements in the docs that are not being adhered to, you could provide a notice of default.  

Sounds like the Buy here pay here car dealers that get a large down payment , wait for the customer to default , repo the car and sell it again . 

No headaches of property management and if they default we get the property back (after a foreclosure of course), but it's gone perfect so far.

And of course the HML wont or should not allow them as a default will cause the first position lender to have to run through a full default/foreclosure to wipe out the lien. 

Lenders may have subsets of rules or guidelines for areas that have very high default rates such as increased min property values or experience being required, but other than LTV's going down for a while by 5% in late 2022 I haven't seen anything crazy.

And if the buyer defaults The seller can foreclose and take title back.Thanks.

Subject-to can have more risk if the buyer defaults or doesn't make payments, whereas a wrap provides a bit more security for the seller.

However, due to it being:1) In the state of California2) A shared home, rather than an outright external property being rented...the default insurance company on offer advised that many carriers are pulling out of CA and that I should go to a local insurance agency.My current insurance for home policy does not offer a "home-sharing endorsement" but only a separate renter's insurance, which would complicate things, since it's for traveling professionals, and they're not going to be booking for 12 straight months.

Down PaymentTypical Down Payment: 10% is a common down payment for seller financing, though you can set this anywhere between 5% and 20%, depending on the buyer's creditworthiness and how much risk you want to take on.Advantages of a Higher Down Payment: The more a buyer puts down, the more equity they have in the property, which can reduce your risk of default.
