Electric or propane?

[Big Flounder]

I am in the the process of getting my house plans drawn up and I have to mak a decision between gas or electric soon. The problem is the property I am building on doesn't have natural gas so if I do go with gas I have to get a tank. I don't like cooking on electric and I am going with a tankless hot water heater. Gas fired water heaters will produce higher flow rates than electric. My question is do any of you guys have propane tanks and how much do you burn a year and what size tanks do you have? Thanks.
