I need assistance with SEO web development and social media presence, and I also need a VA for pre-screening calls to potential motivated sellers.  

Numbers give some idea, but being that there are so many factors (location, stability of job market, tenant selection (no matter what screening system you have, there is a degree of luck here), unforeseen maintenance expenses,and so on...in the end, if you're creative and keep learning, you can make "almost" any deal (within reason) a positive (financial and educational) experience.

@Dexter Ambroise Here is a good guide to screening tenants:http://www.biggerpockets.com/renewsblog/2013/01/27...For the lease... try googling your state + apartment lease or your county + apartment lease

be sure to read the posts on screening a tenant. 

It is all about screening your tenants.  

I'm plan on getting more consistent with it hence my introduction and ultimately active participation in the forums.I found bigger pockets a few years ago while looking for methods for Tenant screening and have been hooked on the podcasts ever since.Right now i'm seeking more knowledge in the Area of Tax Delinquent property acquisitions(Before they get to the Tax auction) and Also wholesalers who are in the Mesa area who may be able to provide some good deals for myself and my partners to flip.I look forward to much more knowledge and want to thank all of you active members for the huge knowledge base that bigger pockets has become just by having your conversations.Thanks, and Hello All!

However my target purchase price would need to be roughly 70% of ARV - rehab costs - assignment fee;  155k - 70% of ARV = $108,500$108,500 - $15k rehab$93,500 - assignment fee= MAO of $87,500Now doing the math and writing this all out, & seeing it on my screen - I have my answer. 

If you are able to find a tenant who is staying there for the long haul and not a nuisance to deal with that would be the ideal choice.If you really feel that you priced it way too low, then I would suggest maybe telling everyone that the unit is no longer available for some reason (construction, re-evaluation of the property, upgrades, etc). then repost it at a higher price and redo the whole screening process.  

Agencies don't bother with or know how to screen without the almighty FICO.   

So, I guess it is same as any renting ... you must screen the tenants very good.
