If you are in an area with hundreds or thousands of listings, it is also impossible to compile the data for houses listed on multiple sites.  

Look for a great existing home, a new build is very expensive and will make it very difficult if not impossible to cash flow unless you buy in a very high rent area.

Its impossible to say from that information.

However, it is not impossible. 

If you don't have a track record of management it may be difficult to pull together but I would not say impossible.

That's not to say they're impossible to find. 

Basically you're best move is likely to buy a 2 unit property (because the FHA guidelines make it near impossible to fit the numbers on 3-4 units in this area) and FHA will loan up to $930k in this area on a duplex which is a $32,550 down payment @ 3.5%.

But almost impossible to even speculate without seeing the property. 

Again without seeing it, it is impossible to say. 

It's tough to accomplish what you want with low income, but it's not impossible.
