Canadian living in US, cross into Canada every day for work?

I am a Canadian and have a full time job in Canada but I am wanting to move just barely south of the border and then drive into Canada every day to work. Basically I want to take advantage of the lower house costs and lower cost of living (food, gas, etc) of the States while retaining my job in Canada. I will get a Nexus card to cut down on commuting time. So my question is that is type of scenario possible/allowed? What do I need in order to do this? Also I have some specific questions:

1) I can probably buy a house outright, but in case I can't, what's involved in getting a mortgage there? Can they look up my Canadian credit information?

2) Do I need any type of visa? I'm not working there at all.

3) Do I need to pay taxes? Maybe property tax?

4) There will never be a 6-month stretch where I am away from Canada, but if you add up the hours (9 hours per weekday plus maybe 10 per weekend) I'm only in Canada for like 120 days in a year. Is this a problem?

Thanks for any input you can provide!
