since you might not know ( disclosure I am a realtor )
in reference to
A) Stronger protections for consumers, since you usually don't get to negotiate term-by-term of your insurance contract...
You can insure in the USA with Chubb, they are rather good at line by line. Also you'll pay more.
B) Overhaul our POS legal system so that most straight-forward civil matters can be resolved without any need for lawyers and unaffordable legal expenses...
Nope it does work, problem is the lag time from stupid laws created till it's removed. sometimes it takes years for the effects of a law to removed. Sorry I can not cite a case.
C) Require a bond or other security from your tenants to offset such potential losses...
Yes, it's called renters insurance, made payable to the landlord, which when a renter is willing to get themselves covered, you will have a corresponding decrease in rental income ( fair is fair since the liability offset and the tenant is paying this in full) . this is my personal preference, For home's yes it's worth it, condo's which are concrete all around with concrete block, electric stoves, and cook-top electric, the loss is minimal maybe 20K so not worth it, most likely covered under your own policy.
As for subletting, If I own the place, I base the revenue on the risk of a 1 year lease, it's all about wear and tear at the end. An asset has a specific life value ( carpets about 5 years, ceramic tiles about 7, wood floors need a full redo every 8 years or so depending ), so if more traffic ( wear and tear ) happens, I need to replace faster. so your little bit of subletting revenue won't offset the risk ( let's not even talk of being party to the sub-let with the insurance company ).
Subletting, while great, is high risk. and if the tenant that sublet to me, does not have a hotel license, I could stay in that place until eviction. ( rental rules are different from hotel rules )
