Thoughts on Vacant Lots

[Shawn Alexander]

So in my area there are a couple vacant lots, I have done some research on the forums and found some good questions to ask such as zoning and titles or liens. My main question is once I purchase the land what is a typical cost to build a duplex/triplex on that land. How much cash should I make sure I have. I know depending in areas ect, but was wondering if anyone had a rough number to see if even looking in lots for duplexs are even in my ball park.

Thanks!
