I am from Windsor, just across the border.  

There is a thin line between confidence and cockiness, and I admit that I like to hug the border of this imaginary line.

I got a guy trying to sell me a duplex on the good/bad price hill border that could make close to $500 a month and I'd only have to put 4k up.

The municipalities in Genesee County that border Oakland and Livingston are very affluent.  

I have one duplex and am about 1.1% and it's working for me.Again, there are guys much more experienced than me on here, hopefully you will get an answer that you can run with.Good luckGB Oh and my duplex is in a Class B, border Class A location if that helps.

Below thee top floor I might cover the bricks with something or paint them a different color or add a border to define ground level.

However, tax liens on houses around the border of metro city of the state, is it as competitive as metro city tax lien bidding?

San Bernardino has a high crime rate compared to many of the bordering cities. 

We try to keep a lot of our properties in the borders.

I'm not an attorney or accountant so you both should talk to cross-border ones to make sure you each do what is best for your specific situation.
