Additionally, the property would make an excellent flip with retail values in the $140k-$190k range in the area.

Your story is excellent.

For myself I've been looking at temporarily relocating to a Midwestern neighborhood enabling me to manage some projects myself in a market where cost of entry is lower and cash more readily available.I think using family money on RE deals can be an excellent way to both increase the volume of deals you can take part in and also enable your family members to benefit from your REI knowledge and skill.

I've seen dozens of homes, I've ran almost hundred deals through paper math, on excel, and a few dozen through BPs rental calculator. 

@Ramesh Ramdatt, Excellent discipline on your part.  

I have read them multiple times and will read them again as they are worth the laughter and are filled with excellent tips.

Does anyone have a referral to an excellent, reliable property management company that is more affordable than the one I am currently with?

I work overseas and file tax returns ( excellent credit) but I find that lenders shy away from lending for investment properties or equity lines on investment properties especially when my overseas employer doesn't provide w2s.Do you think I should continue buying when I have cash, start flipping or look for lenders ?

If you listen to the excellent podcasts you will find that is a popular starting point for many investors. 

Excellent info.
