Most other sources of private money do require that 2 month seasoning period, unless you have a partner with already seasoned money that is on the loan. 

That being said, I’ve made my biggest profits off these houses.

Zillow pre-foreclosures are going to be quite an unreliable source of information, until foreclosed on you will still be dealing with the homeowner. 

whats the biggest red flag ect..

Actually its rated by several sources as a top city to invest in real estate for several factors I'm sure you are aware of.

With a deal this good, I finally decided to look into Hard Money Loans as a potential source of Financing and the lender told me that one of the requirements is that the borrower (or a partner of theirs) must own their Primary Residence.

But the biggest thing i then look for is the cash flow i receive after moving out.

Try places like Fiver and other online work sources

Killeen is the biggest town between Austin and Dallas, and part of the Texas Triangle that I don't see a lot of instability in anytime soon.I love the strategy of buying a multi-family with the VA loan, btw.

Read lots of great stuff from many sources there often.
