I over exaggerate but you get the drift.. if it was a prime property in CA or even here in Oregon and I was 300 a month neg I would hold but not in a market that does not demonstrate any real upward movement

Not only is there a lot wrong but many of the conditions demonstrate amaturish work and dangerous conditions. 

There is no specific holding period required other than you be able to demonstrate that you had the intent to hold for rental/investment should you be audited. 

There are several things you can do to demonstrate your intent.  

Your Business Plan not only needs to motivate you to success, but it needs to demonstrate to your partners and investors that you actually understand the market.  

There are many ways for the LLC to demonstrate that it is separate from an individual (tax ID, checking accounts, books and records, how documents are signed, separate credit cards, business address, etc).Note also that if you ask a corporate attorney about this you will get lots of different answers.

The demonstrated performance is only about 50% lethality.

I had a sub-500 credit score and no money in the bank.So I did what @Chris Seveney suggested to you...I brought on a partner to fund the purchase/rehab of my properties.But here's the thing...you MUST have deals worth consideration and be able to demonstrate how they are profitable to this partner.

I imagine having documented criteria helps demonstrate you're objective, but it also ties your hands as soon as somebody makes the cut.

There are quite a few threads here dealing with the different "classes", but here is a little multi family example to demonstrate the difference .
