Even with the selloff in rates the last few days, we're still near all time lows for cheap money. 

@Dorothy PangI haven’t seen their stuff in a while, but some of their homes uses to be in low Income neighborhoods.

I'd do a search on low cost of living growth (GDP and/or population) markets, if I was you Jerry. 

I'm a Engineer working full time in New York and I'm interested of how people go about investing out of state in a state that has very low or no cash flow.

It sounds like you have very nice tenants, and it is understandable that they would like to keep their housing costs as low as possible.

If you start asking around, a lot of people try the strategy of “buy every time you move” but this only give you some benefits (0% or low money down, low interest rates, etc).

It sounds like it would be a great opportunity to buy low and make a profit, but is it worth it?

Conventional loans require as low as 5% down depending on your credit score and other factors.

Is there anyone you can trust that is in the lowest tax bracket, preferably living in a no or low income tax state?

I personal had insulation redone in my house and low and behold when I sold it it was worth a percentage of that amount higher than I thought because of the way it adds value.If you have any further questions please tag me.
