Many a home owner that is trying to save a couple of bucks will find out the first time they file a claim.
A cheap insurance may not cover repairs 100%.
Many companies will "Pro-Rate" an issue.
Roofing for one. A new roof is worth "X" dollars. They may look at the life of a roof being say 20 years.
If it is 10 years old, you get paid only 50% if the replacement value.
This is very true on many issues.
I am all for saving money, but, I had replacement cost on my policy...when a fire destroyed a shed, Everything got replace new.
For about $100 we didn't have to put out any money to replace our property.
Cheap is not always thrifty.
