.- 2000 sq ft townhouse in Marina Del Rey (upscale CA beach neighborhood)- Good condition, but cosmetically everything is older- Need to upgrade a powder and guest bath where everything stays in the same spot but is replaced- Upgrade master bath, same things as above AND add a clawfoot tub where there is a closet now - 3 feet from nearest water connection (don't have to move walls).

Needed a lot of TLC cosmetically, and did the work ourselves.

The other kind of insurance Canadian banks routinely offer, even if you have 20% or greater downpayment, is credit insurance in case you are unable to make payments due to illness, disability, accident, etc.
