I have also called the local hospital and largest local employers but no real response.

What happens when the tenant has an employment disruption and doesn't pay rent?

Especially, if you have 2 years of employment under your belt.

I plan to get a property later this year and employ the house-hacking strategy (I already have the funds for downpayment and closing).

You may need to employ a resident manager to help out in the beginning.

However I call one of them explained my situation, currently starting, getting to know the value and look for lenders, however his answer was not what i expected, he let me know they are looking for investors with money so they can help them...So I was wondering If you have any advise/opinion/comment on;Would the fist step  be get to know to what financing amount I have access to, based on my employment and credit score?

If I were in your position, I would either - Ask for the nurses contract or recruiter contact to verify employment and use this as the background and credit check (most travel assignments require you to get a background check prior to going to a hospital, and the contract would prove employment and term) - Offer the nurse a month to month rental with options to extend but require my cleaner to go in every month to clean and assess"

Self-employment tax will be required on the net gain, which will of course be 0 after property expenses and depreciation.

I see that makes it about 30 minutes from (for example) Redstone Arsenal, which I know is a major employer. 

@Raj MukherjeeYou are right in your analysis, Huntsville definitely has better schools and the employer profile is much better as well.
