I am thinking to use speedhome but havent explore with them yet.
at least using the one that protect your rent for the entire year. the premium package.

if tenant leave without paying, speedhome will blacklist them and also put a record in CTOS.
they can run but not forever cause they will need to take a loan in the future, but this has nothing to do with landlord as it is with speedhome.

i think to protect the owner ourselves, we need to look at the deal with speedhome, not the tenant.
in terms of electricity there must be a way to overcome this issue.
for aircond use, can always do a sub meter, not expensive or difficult. (easy monitoring)

but is a good sharing, how do you even prevent huge losses on electricity.
did you ask speedhome what kind of protection they give?
